Abstract

A heat curable composition comprises an epoxidized novolac resin and a guanamine of the formula (A)#cB where A is <FORM:0965588/C3/1> #c is 1 or 2 where possible and B represents an aliphatic hydrocarbon radical containing up to 21 carbon atoms, R2NHCH2.CH2-, -CH2CH2.N(R2)CH2.CH2- (where R2 is an aliphatic hydrocarbon radical having from 4 to 21 carbon atoms) or a hydrocarbon radical derived from a dimerised unsaturated fatty acid. Specified epoxides are the epichlorohydrin derivatives of novolacs derived from formaldehyde, acetaldehyde, chloraldehyde, butyraldehyde or furfuraldehyde and cresol, butyl phenol, t-butyl phenol, t-amyl phenol, hexyl phenol, 2-ethyl hexyl phenol, nonyl phenol, decylphenol or dodecyl phenol. Fillers e.g. aluminium oxide may be included in the compositions. The compositions may be partially cured to the storable, curable "B"-stage resins. The examples disclose compositions comprising an epoxidised novolac resin and:-(1) a guanamine of the formula A: <FORM:0965588/C3/2> where R1 has 11 carbon atoms; (2) cocoguanamine; (3) the guanamine of (1) and aluminium oxide; (4) a glycidyl ether of tetraphenol ethane, a guanamine of formula A where R1 is the aliphatic group from hydrogenated tallow oil acids and kaolin; (5) the guanamine of (1) and finely divided mica; (6) the guanamine of (1), flake glass, finely divided walnut shell flour and nylon flock; (7) the guanamine of (1) and shortfibred asbestos; (8) the guanamine of (1) and surface activated kaolin and (9) and (10) the guanamine of (1) and finely divided mica.
