Abstract
A heat-curable composition comprises a guanamine containing the grouping <FORM:0965828/C3/1> and a glycidyl ester of a polymeric fat acid. Specified guanamines are those of the formulae: <FORM:0965828/C3/2> <FORM:0965828/C3/3> <FORM:0965828/C3/4> <FORM:0965828/C3/5> wherein R1 is hydrogen, a phenyl group or an alkyl radical containing up to 21 carbon atoms; R2 is an aliphatic hydrocarbon radical containing from 6 to 22 carbon atoms and R3 is a dimeric hydrocarbon radical derived from a dimerized unsaturated acid. Many conventional polymeric fat acids are specified as being suitable for use in the preparation of the glycidyl esters. The compositions may also contain conventional epoxy resins e.g. the reaction products of epichlorohydrin with bis-phenol-A or resorcinol. The compositions may be partially cured to storable, curable "B-stage" resins. Example 5 describes the preparation of a glycidyl ester from epichlorohydrin and dimerized unsaturated vegetable oil acids and the admixture of this ester with an epoxy resin derived from bis-phenol-A and epichlorohydrin and cocoguanamine. In examples (1), (2), (4), (6), (7) and (8) a glycidyl ester of dimerized tall oil acids is mixed with:-(1) a guanamine of the formula A where R1 is a hydrocarbon radical of the C12 fraction of coconut oil fatty acids; (2) cocoguanamine and black iron oxide; (4) an epoxy resin derived from epichlorohydrin and bis-phenol-A and cocoguanamine; (6) an epoxy resin derived from epichlorohydrin and bis-phenol-A and a diguanamine of formula D where R3 is the hydrocarbon group of dimerized tall oil fatty acids; (7) the guanamine as in (6); (8) an epoxy resin derived from epichlorohydrin and bis-phenol-A and a guanamine of formula C where R2 is a dodecyl group and (9) the guanamine as in (8).ALSO:In Example 3 a layer of an adhesive composition comprising a glycidyl ester of dimerized tall oil acids mixed with cocoguanamine and finely divided black iron oxide is poured on to a steel can lid and cured by the application of heat.
