Novel thermosetting plastic compositions containing certain resins and of the epoxidized fatty guanamines

摘要

A heat-curable composition comprises a poly-epoxide derived from epichlorohydrin and bis(p-hydroxyphenyl) sulphone and a guanamine of the formula FORM:0969257/C3/1 FORM:0969257/C3/2 FORM:0969257/C3/3 or FORM:0969257/C3/4 where R1 is a phenyl, benzyl or aliphatic hydrocarbon radical containing up to 21 carbon atoms, R2 is an aliphatic hydrocarbon radical containing from 4 to 22 carbon atoms and R3 is a divalent hydrocarbon radical derived from a dimerised unsaturated fatty acid. Fillers e.g. glass fibres, clays, asbestos and metallic powders may be present in the compositions which may be partially reacted to a gB-stagea resin. In the examples, an epoxy resin derived from epichlorohydrin and bis(p-hydroxyphenyl) sulphone is cured with (1), (3), (4) and (6) a guanamine derived from coconut oil acid fractions; (2) benzoguanamine and (5) stearoguanamine. Specification 969,256 is referred to.
