Abstract:
1. An anaerobically curable composition comprising: (a) a cyanate ester compound having the structure of formula I: wherein m is from 2 to 5 and R 1 is an aromatic nucleus-containing residue; (b) a (meth)acrylate monomer; (c) one or more maleimides, nadimides or itaconimides selected from the group consisting of the following structures: wherein m=1–15, p=0–15, R 2 is independently selected from the group consisting of hydrogen and lower alkyl, and J is independently selected from the group consisting of a monovalent or a polyvalent moiety comprising organic or organosiloxane radicals, and combinations thereof; and (d) an anaerobic cure-inducing composition comprising peroxide and saccharin, wherein said curable composition is free of added metallic catalyst and cures at room temperature when placed between two surfaces such that an anaerobic environment is created in the area between the two surfaces, at least one of which surfaces having an active metallic surface.
