Abstract
A curable composition comprises a mixture of a polyamide, a primary aromatic diamine and an epoxy resin, said polyamide being derived from a polymeric fatty acid and an aliphatic polybasic amine. Specified polymeric fatty acids are the polymerization products of oleic, linoleic, linolenic, eladic and ricinoleic acid. Specified aliphatic polybasic amines are those of the general formula: <FORM:0872381/IV (a)/1> where R is an alkylene radical and x is an integer less than 6, e.g. ethylene diamine, diethylene triamine, triethylene tetramine, tetraethylene pentamine, 1, 4-diaminobutane, 1, 3-diaminobutane, hexamethylene diamine, 3-(N-isopropyl-amino) propyl amine and 3, 31-imino-bis-propylamine. Preferred aromatic primary diamines are those of the structure H2NR1NH2 where R1 is an arylene radical containing at least one and less than five aromatic nuclei, e.g. m-phenylene diamine, p, p1-methylene dianiline, p-phenylene diamine and 1, 4-diaminonaphthalene. The polyamide and the primary aromatic diamine may be blended by heating at 80 DEG -100 DEG C. Specified epoxy resins are the reaction products of polyhydric phenols, e.g. bis-phenol A with halohydrins and/or glycerol dichlorohydrin, preferably having an epoxy equivalent weight of 125 to 400. In the examples, an epoxy resin derived from bis-phenol A and epichlorohydrin is blended with a blend of polyamide made from a dimerized fatty acid and triethylene tetramine with (1) and (2) m-phenylene diamine and (3) p, p1-methylene dianiline. Specification 726,570, also U.S.A. Specifications 2,379,413, 2,450,940, 2,585,115 and 2,589,245 are referred to.
