Precautions

See Material Safety Data Sheets for hazardous ingredients, flammability, disposal, and related handling

information. Adcote 1740 resin can react or interact with other components of the structure. Retained

solvents, slip additives, antiblock agents, and contaminated solvents are some of the components that may

cause property changes of the substrates and/or Adcote 1740 resin.

General Information

The initial color and clarity of Adcote 1740 resin will remain unchanged after outdoor exposure. In addition,

Adcote 1740 resin is resistant to attack by dilute acid and alkali solut ions. When mixed with coreactant, the

tensile strength and resistance to chemical plasticizers, solvents and water are noticeably improved. The

melting temperature range will also increase. With some substrates, the addition of a coreactant may

improve adhesion.

High molecular weight polyester adhesives like Adcote 1740 have a tendency to form a reversible

structure in solution with time. This structuring is accelerated when the adhesive is exposed to

temperatures below 50°F. The structuring is revers ible if heat and shear are applied to the adhesive. We

recommend placing the container of adhesive in a steam cabinet, allowing venting of the container and

heating to 110

– 140°F. After the adhesive reaches the proper temperature, mix the adhesive in the

container for 1

– 3 hours under moderate shear. Use of a disperser or “Cowles” type blade will shorten the

time needed.

Caution must be taken because of the flammability of the solvents used in the adhesive. Please

review MSDS for hazards associated with the adhesive.

Attempting to redisperse without heat may reduce the apparent viscosity, but not result in a

homogeneous mix. Before using the adhesive, check, to make sure that all resin has returned to a true

solution and no gels remain.

Directions For Use

Apply Adcote 1740 resin by any of the conventional methods, including gravure coater, reverse roll coater,

knife and spraying. Dilution may be necessary. Apply enough wet coating to deposit 0.1

- 0.3 dry mils (or

approximately 2

– 6 dry lbs. per 3000 squ are feet) and completely remove the solvents. Laminate with

heated nip rolls to provide a minimum glue line temperature of 140°F.

The preferred method for bonding is to coat the more stable substrate, heat the glue to a temperature above

140°F, and lamin ate. A heated press can be used for general purpose bonding by employing enough

pressure to insure intimate contact between the adhesive and both surfaces, and holding this pressure until

the glue line reaches 140°F.

When using Coreactant, use the amount shown in the Suggested Coreactants section as a guide. The

optimum level of coreactant should be determined experimentally for each particular end use. Coating with

coreactant is handled in the same manner as without. Curing begins after solvent remova l and continues

slowly at room temperature. Approximately 7

– 14 days are necessary to complete the cure at room

temperature, but a post cure at elevated temperatures can reduce this time.Adcote 1740 December 2006 P age 3 of 5

Pot Life

It is best not to mix more Adcote 1740 resin and coreactan t than will be used in 8 hours. Any mixed solution

that is left over should be stored in tightly closed containers and should be used within 3 days. When

reusing, we recommend that you combine the old mixed solution with newly mixed solution in the ratio of

25% old and 75% new, and mixed thoroughly.

Safety Precautions

Adcote 1740 resin contains somewhat toxic and/or flammable solvents and suitable handling precautions

should be observed. Do not inhale the fumes. Avoid prolonged and repeated contact wit h the skin. Eye

contact must be prevented. Synthetic gloves, face shields, and aprons impermeable to these solvents

should be worn when there is possible skin contact. Use NIOSH approved respirators to avoid fumes.
