ABSTRACT:
Compositions comprising certain acrylate-containing polyorganosiloxanes and a hydroperoxy polymerization initiator are anaerobically curing sealant compositions. For example, a composition comprising a polyorganosiloxane consisting essentially of 42 mole percent trimethylsiloxane units and 58 mole percent methacryloxypropyl silsesquioxane units and cumene hydroperoxide remained uncured for several days in the presence of oxygen but cured to a solid, insoluble sealant when placed on the threads of an iron bolt and a nut was threaded onto the bolt.
