Curable compositions, especially suitable for use as adhesives, contain (A) an anaerobically polymerizable mixture which is stable in oxygen but polymerizes when oxygen is excluded, comprising (i) a free radical polymerizable 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 polymerization (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 araerobic curing mechanism and then develop high strength by cure of the epoxide resin. |
