Abstract:
A resin-reinforced silicone composition curable by exposure to radiation in the electromagnetic spectrum, exposure to moisture and combinations thereof, comprising:(a) a polyorganosiloxane with reactive groups selected from the group consisting of photocurable groups, moisture curable groups, and combinations thereof; (b) a silicone resin selected from (i) those formed from at least one silane within the formula R1mR2pSi(X)4âˆ’(m+p) I, where R1 is a (meth)acrylate functional group or a hydrolyzable group, and R2 may be the same or different and may be selected from the group consisting of monovalent ethylenically unsaturated radicals, hydrogen, C1-12 alkyl, C6-12 aryl, C7-18 alkylaryl, and hydrolyzable groups, X is a hydrolyzable group, m is an integer from 1 to 3, and m+p is an integer from 1 to 3; (ii) those formed from at least one silane within the formula R3qSi(X)4âˆ’q II, where R3 may be the same as or different from R2 above and may be selected from monovalent ethylenically unsaturated radicals, hydrogen, C1-12 alkyl, C6-12 aryl, C7-18 alkylaryl, and q is an integer from 1 to 3, reacted with at least another silane within the formula of R4rR5sSi(X)4âˆ’(r+s) III, where R4 and R5 may be the same or different and may be selected from monovalent ethylenically unsaturated radicals, hydrogen, C1-12 alkyl, C6-12 aryl, C7-18 alkylaryl, r is an integer from 1 to 3, and r+s is an integer from 1 to 3, provided the silicone resin formed contains at least some hydrolyzable group, X; and combinations thereof; and (c) a cure catalyst selected from the group consisting of a photoinitiator component; a moisture curing catalyst, and combination thereof.
