CURABLE COMPOSITIONS ABSTRACT Curable compositions, especially suitable for use as adhesives, contain (A) an anaerobically polymerisable mixture which is stable in oxygen but polymerises when oxygen is excluded, comprising (i) a free radical polymerisable compound, such as an acrylate or methacrylate ester, (ii) an organic free radical initiator, such as a peroxide or hydroperoxide, and (iii) an organic accelerator of free radical polymerisation (B) an epoxide resin, and (C) a curing agent for epoxide resins that is a basic curing agent, a polymercaptan, or a polyhydric phenol. These compositions cure rapidly by an anaerobic curing mechanism and then develop high strength by cure of the epoxide resin.
