Patent GB-914778-A (GB)
Title: Coating composition
IPC: C09D155/04
Filed: 1960-07-27
Abstract: A coating composition consists of 10-50% of a polymethyl ether of a polymethylol melamine blended with 50-90% of the ammonium salt of either the dimer of an unsaturated fatty acid or the adduct of such an acid and a polymerizable styrene such as styrene, o-, m-, or p-methyl- or chloro-styrenes; 2,4-, 2,5-, or 3,4-dimethyl styrenes; 2,4-dichlorostyrene; or a -methyl- or chloro-styrenes, singly or in mixtures.  Divinyl benzene may also be added in amounts of 10-12% by weight of total vinyl compounds. The composition may be used in a water dispersion, with or without pigments.  In the examples, hexamethyl ether of hexamethylol melamine was blended, in the presence of water and sufficient ammonia to neutralize the acids, with (1) dehydrated castor oil fatty acids -o-methyl styrene adduct; (2) as in (1), but post bodied by addition of di-tertiary butyl peroxide; (3) dimer of dehydrated castor oil fatty acids and adduct of styrene and dehydrated castor oil fatty acids; (4) the post-bodied adduct of dehydrated castor oil with vinyl toluene and divinyl benzene; (5) adduct of doubly-distilled tall oil fatty acids and vinyl toluene with 10% divinyl benzene.ALSO:An adduct of an unsaturated fatty acid and a polymerizable styrene is made by heating the acid to about 120 DEG -about 160 DEG C. with stirring and adding in small portions a mixture of the styrene and a peroxide catalyst, followed by heating for 10 minutes-4 hours, at 120 DEG -160 DEG C. This procedure is said to reduce dimerisation of the acid and homopolymerization of the styrene, and yield a product wherein only one molecule of styrene adds to each double bond in the acid.  From 0.5 to 2, preferably 1, mole of styrene per mole of acid is used. Suitable acids are: myristoleic, palmitoleic, oleic, linoleic, linolenic, elaeostearic, licanic, ricinoleic, erucic, cetoleic, petroselic, nervonic, clupadonic, stearolic, behenolic, and brassidic, or mixtures thereof, particularly those from glyceride oils, e.g. dehydrated castor, linseed, soya, and fatty acid portion of tall. Suitable styrenes are: styrene; o-, m-, p-, and a -methyl or -chloro styrene; 2,4-, 2,5- or 3,4-dimethyl styrene; 2,4-dichloro styrene, or mixtures.  10-12% by weight, based on the styrene, of divinyl benzene may also be added.  Suitable catalysts are benzoyl peroxide, cumene hydroperoxide, and t-butyl hydroperoxide.  The adduct is converted to its ammonium salt by adding ammonium hydroxide, and this salt is used to prepare coating compositions.

Abstract: 1344390 Cooling moulds PONT-A-MOUSSON SA 19 April 1971 [17 April 1970] 26399/71 Heading B3F [Also in Division G3] In a casting apparatus where moulds are sequentially presented to at least two waterspray cooling stations, a first station sprays the moulds with a predetermined constant rate of flow while a following station sprays the moulds intermittently or at a rate as determined by a device measuring the temperature of the moulds. Centrifugal casting moulds 2 rotating about horizontal axes are presented sequentially to a cleaning station I, coating station II, casting station III, cooling stations IV, V, VI and extracting station VII by clockwise rotation of a turntable 1. At cooling stations IV and V water is sprayed on the moulds from pipes 8a at a rate determined by setting a flow regulator 10. At cooling station VI the spray water flow in conduit 8b is controlled in accordance with the temperature of the mould in station VII measured by a pyrometer 17 which feeds a signal to a pneumatic or electronic control device 15. The control device 15 operates an electrically actuated cut-off valve 14, through a line 19 such that when a predetermined low mould temperature is detected the cooling spray is stopped and when a predetermined high mould temperature is detected the cooling spray is recommenced. Alternatively the cut-off valve 14 can be replaced by a flow rate controller 13 which is operated by controller 15 in dependence on the measured mould temperature through a line 19a. The mould temperature can be indirectly measured by determining the temperature of the castings P just after ejection from the moulds at station VII.
