Abstract
A one package, stable curable composition contains: PA0 (a) a nonfunctional polydiene; PA0 (b) a polyepoxide; PA0 (c) a sulfur and zinc containing vulcanization system adapted to cure the polydiene and the polyepoxide; and PA0 (d) an anhydride containing material effective to promote adhesion of the curable composition to metal, wherein the anhydride containing material remains essentially unreacted with the epoxide and is combined in a manner to obtain dissolution of the anhydride containing material in the epoxide. The aforesaid curable composition is suitable for use as an adhesive or sealant.
