Abstract
An anaerobically curing composition is comprised of (i) a silicone fluid formed as the reaction product of at least one first silane of formula I: EQU R.sub.n Si(X).sub.4-n (I), wherein the R groups are the same or different and selected from the group consisting of hydrogen, C1-C12 alkyl, C6-C12 aryl, C7-C18 arylalkyl, C7-C18 alkylaryl, haloalkyl, haloaryl and monovalent ethylenically unsaturated radicals excluding (meth)acryloxy functional groups, X is a hydrolyzable functionality, and n is an integer of from 0 to 3, and at least one second silane of formula II: EQU R.sup.1.sub.m R.sup.2.sub.p Si(X).sub.4-(m+p) (II), wherein R.sup.1 is a (meth)acrylic functional group and R.sup.2 can be the same or different and is selected from the group consisting of monovalent ethylenically unsaturated radicals, hydrogen, C1-C12 alkyl, C6-C12 aryl, C7-C18 arylalkyl, and C7-C18 alkylaryl, X is a hydrolyzable functionality, m is an integer from 1 to 3, and m+p is an integer from 1 to 3; (ii) a polymerizable organic (meth)acrylate monomer; and (iii) polymerization initiator.
