LUBRICANT AND SURFACE CONDITIONER SUITABLE FOR CONVERSION COATED METAL SURFACES

Abstract: An excellent lubricant and surface conditioner layer on formed metal surfaces, particularly aluminum cans that have been previously provided with a chromium oxide conversion coating, can be formed by contacting the cans with an aqueous lubricant and surface conditioner forming composition that contains at least one oxa acid or methyl ester thereof corresponding to the general formula (I): CH3(CH2)nO(CH2CH2O)xCH2C(O)OR, where each of n and x, which may be the same or different, is a positive integer and R represents H or CH3 and at least 20 weight % of the total content corresponding to the general formula (I) does so when x is at least 8, and then drying the thus-treated cans.

Description: Description LUBRICANT AND SURFACE CONDITIONER SUITABLE FOR CONVERSION COATED METAL SURFACES BACKGROUND OF THE INVENTION Field ofthe Invention This invention relates to improvements in processes and compositions which ac¬ complish at least one, and most preferably all, of the following related objectives when applied to formed metal surfaces, more particularly to the surfaces of cleaned and con¬ version coated aluminum and/or tin plated cans: (i) reducing the coefficient of static friction ofthe treated surfaces after drying of such surfaces, without adversely affecting the adhesion of paints or lacquers applied thereto; (ii) promoting the drainage of water from treated surfaces; and (iii) lowering the dryoff oven temperature required for dry- ing said surfaces after they have been rinsed with water. Discussion of Related Art The following discussion and the description of the invention will be set forth primarily for aluminum cans, as these represent the largest volume area of application of the invention. However, it is to be understood that, with the obviously necessary modifications, both the discussion and the description ofthe invention apply also to tin plated steel cans and to other types of formed metal surfaces for which any ofthe above stated intended purposes ofthe invention is practically interesting. Aluminum cans are commonly used as containers for a wide variety of products. After their manufacture, the aluminum cans are typically washed with acidic cleaners to remove aluminum fines and other contaminants therefrom. Recently, environmental considerations and the possibility that residues remaining on the cans following acidic cleaning could influence the flavor of beverages packaged in the cans have led to an in¬ terest in alkaline cleaning to remove such fines and contaminants. However, the treat¬ ment of aluminum cans with either alkaline or acidic cleaners generally results in dif- ferential rates of metal surface etch on the outside versus on the inside of the cans. For example, optimum conditions required to attain an aluminum fine-free surface on the inside of the cans usually leads to can mobility problems on conveyors because of the increased roughness on the outside can surface. Aluminum cans that lack a low coefficient of static friction (hereinafter often abbreviated as "COF") on the outside surface usually do not move past each other and through the trackwork of a can plant smoothly. Clearing the jams resulting from fail¬ ures of smooth flow is inconvenient to the persons operating the plant and costly be- cause of lost production. The COF of the internal surface is also important when the cans are processed through most conventional can decorators. The operation of these machines requires cans to slide onto a rotating mandrel which is then used to transfer the can past rotating cylinders which transfer decorative inks to the exterior surface of the cans. A can that does not slide easily on or off the mandrel can not be decorated properly and results in a production fault called a "printer trip". In addition to the mis- loaded can that directly causes such a printer trip, three to four cans before and after the misloaded one are generally lost as a consequence of the mechanics of the printer and conveyor systems. Thus, a need has arisen in the can manufacturing industry, particu¬ larly with aluminum cans, to modify the COF on the outside and inside surfaces of the cans to improve their mobility. Past improvements in this respect have led to still fur¬ ther increases in conventional can processing speeds, so that only the lower part of the range of previously acceptable COF values is now acceptable in many plants. An important consideration in modifying the surface properties of cans is the concern that such modification may interfere with or adversely affect the ability of the cans to be printed when passed to a printing or labeling station. For example, after cleaning the cans, labels may be printed on their outside surface, and lacquers may be sprayed on their inside surface. In such a case, the adhesion ofthe paints and lacquers is of major concern. It is therefore an object of this invention to improve mobility with¬ out adversely affecting adhesion of paints, decorating inks, lacquers, or the like. In addition, the current trend in the can manufacturing industry is directed to¬ ward using thinner gauges of aluminum metal stock. The down-gauging of aluminum can metal stock has caused a production problem in that, after washing, the cans require a lower drying oven temperature in order to pass the column strength pressure quality control test. However, lowering the drying oven temperature resulted in the cans not being dry enough when they reached the printing station, and caused label ink smears and a higher rate of can rejects. One means of lowering the drying oven temperature would be to reduce the amount of water remaining on the surface ofthe cans after water rinsing. Thus, it is ad¬ vantageous to promote the drainage of rinse water from the treated can surfaces. In summary, it is desirable to provide a means of improving the mobility of aluminum cans through single filers and printers to increase production, reduce line jams, minimize down time, reduce can spoilage, improve or at least not adversely affect ink laydown, and enable lowering the drying oven temperature of washed cans. In the most widely used current commercial practice, at least for large scale op¬ erations, aluminum cans are typically subjected to a succession of six cleaning and rins¬ ing operations as described in Table A below. It is preferable to include another stage, usually called "Prerinse", before any of the stages shown in Table A; when used, this stage is usually at ambient temperature (i.e., 20 - 25 °C) and is most preferably supplied with overflow from Stage 3 as shown in Table A, next most preferably supplied with overflow from Stage 1 as shown in Table A, and may also be tap water. Any of the rinsing operations shown as numbered stages in Table 1 may consist of two or preferab- ly three sub-stages, which in consecutive order of their use are usually named "drag- out", "recirculating", and "exit" or "fresh water" sub-stages; if only two sub-stages are used, the name "drag-out" is omitted. Most preferably, when such sub-stages are used, a blow-off follows each stage, but in practice such blow-offs are often omitted. Also, any ofthe stages numbered 1 and 4 - 6 in Table A may be omitted in certain operations. It is currently possible to produce a can which is satisfactorily mobile and to which subsequently applied inks and/or lacquers have adequate adhesion by using suit¬ able surfactants either in Stage 4 or Stage 6 as noted above. Preferred treatments for use in Stage 6 are described in U. S. Patents 4,944,889 and 4,859,351, and some of them are commercially available from the Parker Amchem Division of Henkel Corpor- ation (hereinafter often abbreviated as "PAM") under the name "Mobility Enhancer™ 40" (hereinafter often abbreviated "ME-40™"). However, it has been found that when a conversion coating, particularly a highly preferred conversion coating formed by treating the can surfaces with an aqueous liquid composition containing simple and complex fluoride ions along with phosphoric, nitric, and gluconic acids, is used in step 4, without any additional material to promote the formation of a lubricant and surface conditioning Table A STAGE ACTION ON SURFACE DURING STAGE NUMBER 1 Aqueous Acid Precleaning 2 Aqueous Acid and Surfactant Cleaning 3 Tap Water Rinse 4 Mild Acid Postcleaning, Conversion Coating, or Tap Water Rinse 5 Tap Water Rinse 6 Deionized ("Dl") Water Rinse layer on the substrate surface, ME-40™ sometimes does not produce satisfactory results when used in Stage 6 as shown in Table A. DESCRIPTION OF THE INVENTION Object ofthe Invention A major object of the present invention is to provide a lubricant and surface conditioner forming composition (hereinafter usually abbreviated as "LSCFC") that will achieve satisfactory COF reduction when used as the last aqueous treatment before drying the cans ("final rinse"), even on can surfaces already coated with a conversion coating by an earlier treatment stage. An alternative and/or concurrent objective is to overcome at least one of the difficulties with the prior art noted above. Other objects will be apparent from the further description below.

Materials according to general formula (I) may be used to¬ gether with other surfactants, including some constituents of previously known lubri¬ cant and surface conditioner forming compositions, and in some but not all instances, a further improvement in properties can be obtained in this way. Polyalkylene oxide block containing ethers and esters are particularly useful auxiliary surfactants when used together with compounds according to formula (I), which may be denoted hereinafter as the "primary lubricant and surface conditioner forming component". Other optional and conventional materials such as biocides, antifoam agents, and the like may also be included in the compositions according to the invention without changing the essence ofthe invention.

Any conversion coating which is contacted with a lubricant and surface condi¬ tioner forming composition according to this invention preferably has been formed as described in U. S. Patent 4,148,670 of April 10, 1979 to Kelly, the entire specification of which, except to any extent that it may be inconsistent with any explicit statement herein, is hereby incorporated herein by reference. The effective fluoride activity ofthe conversion coating forming aqueous liquid composition for purposes of this description is measured by use of a fluoride sensitive electrode as described in U. S. Patent 3,431,182 and commercially available from Orion Instruments. Fluoride activity was specifically measured relative to a 120E Activity Standard Solution commercially available from the Parker Amchem ("PAM") Division of Henkel Coφoration by a procedure described in detail in PAM Technical Process Bulletin No. 968, Revision of April 19, 1989. The Orion Fluoride Ion Electrode and the reference electrode provided with the Orion instrument are both immersed in the noted Standard Solution and the millivolt meter reading is adjusted to 0 with a Standard Knob on the instrument, after waiting if necessary for any drift in readings. The electrodes are then rinsed with deionized or distilled water, dried, and immersed in the sample to be measured, which should be brought to the same temperature as the noted Standard Solution had when it was used to set the meter reading to 0. The reading of the electrodes immersed in the sample is taken directly from the millivolt (hereinafter often abbreviated "mv" or "mV") meter on the instrument. With this instrument, lower positive mv readings indicate higher fluoride activity, and negative mv readings indicate still higher fluoride activity than any positive readings, with negative readings of high absolute value indicating high fluoride activity. The fluoride activity of the conversion coating forming com- position preferably is not more than, with increasing preference in the order given, -50, -60, -70, -80, -85, or -89 mv and independently preferably is at least, with in- creasing preference in the order given, -120, - 1 15, -1 10, - 105, -100, -95. or -91 mv. The temperature at which the conversion coating composition is contacted with the metal substrate being treated, before being contacted with a lubricant and surface conditioner forming composition according to the invention, preferably is at least, with increasing preference in the order given, 25, 30, 35, 38, or 40 °C and independently preferably is, primarily for reasons of economy, not more than, with increasing prefer¬ ence in the order given, 70. 60, 55, 50, 45, 43, or 41 °C, and the time of contact at these temperatures preferably is at least, with increasing preference in the order given, 1 , 3, 5, 7, 9, 1 1, 13, 15, 17, 19, 21, 23, or 24 sec and independently preferably is, primarily for reasons of economy, not more than, with increasing preference in the order given, 600, 300, 200, 180, 150, 120, 100, 80, 70, 60, 50, 40, 35, 32, 29, 27, or 26 sec. Before conversion coating, the metal surface to be treated should be well cleaned, preferably with an acid cleaning composition, more preferably one that also contains fluoride and surfactants. Suitable cleaners are known to those skilled in the art. The invention and its advantages may be further appreciated by consideration of the following working examples and comparisons.

Cleaner Solutions: The cleaning solutions were prepared using Ridoline® 123 concen- trate, ammonium bifluoride, aqueous hydrofluoric acid (Reagent Grade at 52 %), sul¬ furic acid (66° Be), and aluminum sulfate as described in the PAM Technical Process Bulletin No. 1580 dated January 3, 1994 for the Ridoline® 123 Process. The Free Acid, Total Acid and Fluoride Activity of the cleaner solution were checked as 5 described in this Technical Process Bulletin. It addition to the five components listed above, ammonia was added if the Free Acid of the initially prepared solution was higher than desired. Four different cleaner solutions were used to prepare cans for these examples; these solutions consisted of water, the ingredients specified below, and amounts ofthe o other ingredients listed above to produce the characteristics listed below, in the manner described in the Technical Process Bulletin. Cleaner Solution #1 ("CS#1 ") contained 1.132 weight/volume %' of Ridoline® 123 concentrate and had Free Acid at 8 points, Total Acid at 18 points, and a Fluoride Activity of +30 mV, measured as described above for the conversion coating composition. Cleaner Solution #2 ("CS#2") had the s same characteristics as CS#1, except that the Fluoride Activity was 0 mV. Cleaner So¬ lution #3 ("CS#3") was the same as CS#2 except that it also contained 1000 parts per million in total ofa lubricant mixture which consisted of 26.75 % of LTC CL 300 Cup¬ ping Lubricant and 73.25 % of LTC DF 50 bodymaker coolant. Cleaner Solution #4 ("CS#4") contained 1.698 weight/volume % of Ridoline® 123 concentrate and had Free 0 Acid at 12 points, Total Acid at 32 points, and a Fluoride Activity of 0 mV. Conversion Coating Solutions: A 0.5 or 0.25 volume/volume % solution of Alodine® 404 concentrate was prepared. Aqueous ammonia was added as required to adjust the pH ofthe solution to the desired value. Aluminum nitrate solution was added to adjust the Fluoride Activity to -90 V. The temperature of this solution was maintained at 5 40.5 °C as it was sprayed onto the cleaned cans. Lubricant and Surface Conditioner Forming Compositions: These compositions were prepared by adding to deionized water the surfactants to be tested. Specifics are report¬ ed in tables below. Apparatus and Procedure All cans were prepared on a laboratory carousel can washer "'Weight/volume %" means that the weight ofthe material so specified contained within a given volume is equal to the weight ofthe stated percentage of the same given volume of pure water. Thus, 10 weight/volume % = 100 grams per liter, 1 weight/volume % = 10 grams per liter, etc. which has been designed so that, in most respects 2 , it closely simulates commercial large scale operations. Each run used fourteen cans. The procedure used to prepare cans was that given in Table 1 unless otherwise noted below.

The interior coating used for all the cans was Glidden 640C552, a water¬ borne coating supplied by the The Glidden Company (Division of ICI Paints), Westlake, OH. The interior coating weight was 135 - 140 mg/0.35 liter (12 fluid ounces) size can. Various labels were applied to the exterior ofthe cans. They all The time periods for rinsing, standing, and blowing-off operations are higher in the laboratory apparatus, because it has only a single spray chamber, which must be used for all stages ofthe process. As a result, longer draining, rinsing, and blowing-off times are required in the laboratory apparatus to avoid contamination. In commercial scale apparatus, there are separate chambers for each spraying and blowing-off step, so that much shorter times can be used. Extensive experience, however, has established that this difference between laboratory and commercial practice does not normally affect the results achieved. consisted of inks supplied by INX, Inc., Elk Grove Village, IL. All labelled cans were then coated with PPG 2625XL Overvarnish, supplied by PPG Coφ. in Delaware, OH. Test Procedures Coefficient of Friction of the Exterior Sidewalls ("COF"): The cans were evaluated for this property, after completion of the steps shown in Table 1 , with a laboratory static friction tester. This device measures the static friction associated with the outside side¬ wall surface characteristics of aluminum cans. This is done by using a ramp which is raised through an arc of 90° by using a constant speed motor, a spool and a cable at¬ tached to the free swinging end of the ramp. A cradle attached to the bottom of the ramp is used to hold two cans on their sides in horizontal position approximately 13 millimeters apart, with their domes facing the fixed end of the ramp and restrained from sliding along the ramp as it is raised by the cradle. A third can is laid on its side upon the first two cans, with the dome of the third can facing the free swinging end of the ramp, and the edges of all three cans are aligned so that they are even with each other. The cradle does not restrain the movement of the third can. As the ramp begins to move through its arc, a timer is automatically actuated. When the ramp first reaches an angle at which the third can slides freely from the two lower cans, a photoelectric switch shuts off the timer. The elapsed time, recorded in seconds, is commonly referred to as "slip time" . The coefficient of static friction is equal to the tangent of the angle swept by the ramp at the time the can begins to move. This angle in degrees with the particular apparatus used is equal to [4.84 + (2.79*t)], where t is the slip time. (The angle at which the can begins to slip is sometimes reported alternatively or additionally to characterize the mobility of the cans tested.) Dome Staining: The domes were removed from the cans to be tested. They were im- mersed in a solution which consisted of 0.2 gram per liter of sodium tetraborate decahy- drate and 0.1 gram per liter of potassium chloride in deionized water. The pH of this solution was adjusted to 9.2 using either sodium hydroxide or hydrochloric acid. It was heated to 68.3 ° C. The can domes were immersed in the hot solution for 30 minutes. (Each batch of this solution was used for only one test.) The can domes were then re- moved, rinsed with deionized water and dried. The following scale was used to report the dome staining performance of the domes: 5 = Best, no discoloration to 0 = com¬ plete dark discoloration, equivalent to the performance of a can without a conversion coating. Adhesion Testing: The domes of the cans to be tested were removed from the side¬ walls. The sidewalls were straightened. The can sections were immersed in a boiling solution consisting of 0.33 g/l of magnesium sulfate heptahydrate. 0.33 g/l of calcium chloride dihydrate, 0.17 g/l of calcium carbonate and 0.7 % by volume of liquid deterg- ent in deionized water for 15 minutes. In those tests described as with "US detergent" in the following text and tables, a concentration of 7 ml/1 of Dawn™ Free detergent from Proctor and Gamble was used. A Chilean detergent which was obtained from Reynolds in Chile was used in examples noted to be with "Chilean detergent". This Chilean detergent was a green viscous liquid with a citrus odor. Its manufacturer, chemical characteristics, and name are not known. The can sections were removed from the test solution, rinsed with deionized water and dried with a paper towel before testing. The areas to be tested, which were the center of the interior dome, the interior sidewall and the exterior sidewall, were scribed in a pattern consisting of two sets of five parallel scribes which intersected at right angles. Two areas, one near the open end of the can and one near the dome end, were scribed on each of the interior and exterior sidewalls. Scotch® Brand No. 610 adhesive tape was applied to the scribed area and removed in a smooth motion. No loss of coating from the taped area, reported as a rat¬ ing of 10, the highest rating possible in this test, was observed in any case reported be- low where the adhesion was measured. Specific Examples Comparative Examples Group 1 : These examples were designed to test the effect of the Fluoride Activity of the cleaner and the pH of the Alodine® 404 conversion coating solution on the COF and organic coating adhesion of cans which have received a final rinse with an aqueous solution of Ethox™ MI- 14. The effect of the concentration of the Ethox™ MI-14 was also investigated. The results of these examples are reported in Table 1.1.

"High" means pH 3.1; "Low" means pH 3.4. The cleaning composition used was CS#1 or CS#2 as defined above. Statistical analysis of the data in Table 1.1 indicates that the Fluoride Activity of the cleaner has no significant effect on the COF of the cans. The COF becomes lower as the concentration of Ethox™ MI- 14 increases. The application of a conversion coat¬ ing to cans prior to the final rinse increases their COF. The higher pH conversion coat- ing solution, "AL 404-Low", does not increase the COF of conversion coated cans as much as the more active conversion coating solution with pH = 3.1 , "AL 404-High." None of the variables tested had any effect on the adhesion of organic coatings or the dome staining performance of the conversion coated cans. When the concentra¬ tion of Ethox™ MI- 14 was greater than 0.2 g/l, there were noticeable deposits of dried white residue in the exterior dome, at the contact marks (the region where adjacent cans touch), at the low point of the interior dome and along the cut edge (open end) on the can. (Cans are dried with their open ends pointing down.) There was no loss of adhesion of the organic coatings in the areas where the white deposits were observed. There were, however, voids in the decoration on the ex- terior of the cans where the ink was not transferred to the can in these areas during the printing process. These voids in the ink are objectionable to users. Thus, although fully acceptable COF values below about 0.65 can be achieved when the concentration of Ethox™ MI- 14 is high enough, the cans would fail to meet many customers' quality requirements because of the missing ink. Examples and Comparison Examples Group 2: This Group was designed to determine the ability ofthe SF series oxa acid methyl esters and Trylox® 5922 to reduce the COF of aluminum cans which have been conversion coated by an Alodine® 404 process, relative to the reduction in COF achieved with Ethox™ MI- 14. Some of the experi¬ mental solutions consisted of equal parts by weight of the oxa acid methyl esters and either Ethox™ MI- 14 or Tergitol™ Nonionic Detergent Min-foam IX. The cleaning solution used was CS#4 as described above. Results are reported in Table 2.1. Three of the four materials tested, SF 7063, SF 71 12 and Trylox® 5922, gave lower COF's than Ethox™ MI- 14. The addition of Ethox™ MI- 14 to the SF 71 12 , SF 7147 and Trylox® 5922 lowers the observed COF. However, only the cans which were rinsed with the solution of SF 7063 had a COF below 0.65. Only these cans were dec¬ orated and tested for adhesion. The adhesion test results are in Table 2.1.

Example and Comparison Example Group 3: The ability of Neodox™ 23-6 and Neo¬ dox™ 25-1 1 to reduce the COF of cans which have been conversion coated with Alo- dine® 404 was tested in this Group. The effect of lower solution pH and of Ethox™ MI- 14 and Triton™ N-l 01 additives to solutions of the Neodox™ materials on water- break, COF and coating adhesion was also tested. The results of these tests, in all of which the cleaning solution was CS#3 as defined above and the pH and Fluoride Activ¬ ity of the conversion coating forming composition were 3.1 and -90 V respectively, are reported in Table 3.1, parts A and B — the identification numbers in both parts of Table 3.1 indicate the same example, with some results reported in part A and others in part B.

The values of 0.43 and lower are among the lowest ever observed on clean cans. At the lowest concentration, both Neodox™ materials gave extensive water-break, par¬ ticularly on the exterior sidewalls of the cans. Neodox™ 23-6 gave water-break free cans at only the highest concentration, 0.8 g/l. With Neodox™ 25-1 1 the cans were water-break free at 0.2 g/l. The addition of sulfuric acid to the solution of Neodox™ 23-6 to give a pH of 2.95 reduced the extent of the water-break. This solution had a very high conductivity of 500 μSiemens. According to past experience, a Stage 7 lubri¬ cant and surface conditioner forming composition with a conductivity of greater than 50 μSiemens usually results in adhesion failures. The addition of either Ethox™ MI- 14 or Triton™ N-l 01 to Neodox™ 23-6 reduced both the amount of water-break and the COF of cans. The addition of 0.05 g/l of Triton™ N-l 01 to a solution which contained 0.05 g/l of Neodox™ 25-1 1 gave cans which were water-break free and which had a low COF. Cans from these examples were decorated on a commercial can processing line and then tested for adhesion. No adhesion loss was observed on any of the cans tested. The use of a Stage 7 lubricant and surface conditioner forming composition which con¬ tained Neodox™ surfactant did not reduce the dome staining resistance of the cans which were conversion coated with Alodine® 404 — domes from every instance shown in Table 3.1 , except Comparison Example 3.15 which had no treatment according to the invention, were rated perfect for this characteristic. Voids in the ink application were observed when the concentration of either Neodox™ surfactant in the Stage 7 lubricant and surface conditioner forming composition was greater than 0.4 g/l, but not at lower concentrations. Example and Comparison Example Group 4: These examples were performed to in¬ vestigate the following: (1) the ability of Neodol™ 25-7, a compound somewhat similar in structure to Neodox™ 23-6, differing only in the distribution of the carbon chain lengths in the base alcohol and the functional group on the terminal carbon in the polyoxyethylene chain, which is an alcohol for the Neodol™ material and a carboxylate for the Neodox™ material, to function as a Stage 7 lubricant and surface conditioner forming composition when applied over an Alodine® 404 conversion coating; (2) the ability of 1 : 1 mixture of Neodox™ 25-1 1 and Triton™ N-l 01 to function as a Stage 7 lubricant and surface conditioner forming composition when applied to cans which have not been conversion coated; and (3) the effect of drying oven temperature and drying time on the COF of cans which have been conversion coated by an Alodine® 404 process and contacted with a 1 : 1 mixture of Neodox™ 25-1 1 and Triton™ N-101. The cleaning solution used was CS#3 as defined above. Results are shown in Table 4.1.

Although Neodol™ 25-7 is more effective than Ethox™ MI- 14 in reducing the COF of cans which have been conversion coated with Alodine® 404, it does not pro¬ duce cans with COF values of no more than 0.65 unless the concentration is raised to the usually uneconomical level of 0.8 g/l. The mixture of Neodox™ 25-11 and Triton™ N-l 01 also gives a very low COF when it is applied to cans which have not been conversion coated. Increasing the tem¬ perature of the drying oven to 200 °C (392 °F) gives a higher COF than does a drying oven temperature of 150 °C (302 °F). Prolonged exposure to the higher drying temper¬ ature (10 minutes vs 5 minutes) gives a large increase in COF. 0 Example Group 5 : A very suitable concentrate composition according to the invention consists ofthe following ingredients: 25 parts of Neodox™ 25-1 1 ; 25 parts of Triton™ N-100; 0.0025 parts of Kathon™ 886MW; and water to a total of 1000 parts. Other ex¬ cellent concentrate compositions according to the invention may be conveniently pre¬ pared from a base stock material that incorporates antifoam agents together with highly concentrated active ingredients for formation of a lubricant and surface conditioner coating on substrates. This base stock consists of 36 parts of Neodox™ 25-1 1 and 54 parts of Triton™ N- 101 surfactants, and 5 parts each of Colloids 999™ and GP 295™ antifoam agents. Typical concentrates according to the invention contain 25 to 60 parts of this base stock together with 0.025 parts of Kathon™ 886MW biocide with the balance to 1000 parts being water. Deionized water is normally preferred for versatility and quality control, but in some locations tap water is also satisfactory. Example and Comparison Example Group 6: CS#2 cleaning solution as described above was used for this group. Other pro¬ cess characteristics were as shown in Table I . The active ingredients of the lubricant and surface conditioner forming compositions used, the resulting angles of first slip, which are related to the COF values as described above, and statistical parameters relat¬ ed to the average first slip angle values are all shown in Table 6.1 . All of the cans prepared using the LSCFC's tested in this experiment were 100 % water-break free after the final rinse. The simultaneous procedure of RS/1 ® Release 4.3, (Bolt Beranek and Newman, Inc., Software Products Division, Cambridge, MA), was used to simultaneously compare the mean COF values of all the experimental runs to determine where significant differences between the groups exist. The Student-Newman-Keuls multiple range test was used to compare each group of COF values with every other group, with the following conclusions: Aluminum cans that had been conversion coated with Alodine® 404 had a sig¬ nificantly lower mean COF when an LSCFC which contained both Neodox ® 25-1 1 and a nonionic surfactant was applied than when the LSCFC contained only Neodox ® 25- 1 1. The COF of cans that were treated with LSCFC's which consisted solely of Neodox ® 91 -7 or Neodox 91 -5 were not significantly different from the COF of cans to which no LSCFC was applied.

When LSCFC's which contained Neodox ® 25-1 1 and one of the nonionic sur- factants Plurafac ® D-25, Neodol ® 25-7, Tergitol ® TMN-6, Tergitol ® 15-S-9, Tergitol ® Min-Foam IX, Surfonic LF-17, Ethox ® MI- 14, Ethal OA-23, Pluronic ® L-61 and Pluronic ® 31R1 , was applied to cans which had been conversion coated with Alodine ® 404, the mean COF did not differ significantly at the 95 % confidence level from the mean COF obtained when an LSCFC consisting of Neodox ® 25- 1 1 and Triton ® N-l 01 was applied to a conversion-coated aluminum can. The LSCFC which contained Car- bowax™ 350 was the only one tested which gave a significantly higher COF than the LSCFC which contained Triton ® N-l 01. Example and Comparison Example Group 7: This group was especially designed to in- vestigate more varied ratios between the primary and auxiliary surfactants than had been tested in Group 6. All procedures for this group were the same as for Group 6, except that (i) some cans that had not been conversion coated were tested along with cans that had been conversion coated as in Group 6 and (ii) the particular LSCFC's used were as shown in Table 7.1 below for cans that had not been conversion coated and in Table 7.2 for cans that had been conversion coated. In other experiments, the percent water-break-free surface produced on cans without conversion coating was measured, and these results are given in Table 7.3. All conversion coated cans produced completely water-break-free surfaces in these tests. If the cans have not been conversion coated and water-break-free surfaces are desired as usual, the ratio of nonionic auxiliary surfactant to oxa-acid surfactant should be at least 1.5: 1.0 when all of the oxa-acid surfactant includes blocks of at least eight oxyethylene groups in each of its molecules.
