Abstract:
A radiation and moisture-curable silicone composition, comprising:(A) a first silicone fluid, said first silicone fluid comprised of a monovalent ethylenically unsaturated functional group endcapped silicone, said endcapped silicone being the product of a reaction between a silanol terminated silicone and a silane crosslinker having joined directly to a silicon atom thereof a monovalent ethylenically unsaturated functional group and at least 2 hydrolyzable groups; (B) a second silicone fluid, said second silicone fluid comprised of a (meth)acryloxy-functional capped silicone fluid capable of UV curing, said (meth)acryloxy-functional capped silicone fluid being formed as a reaction product of: (i) a silyl di(meth)acrylate compound of the formula: â€ƒwherein R1, R2, R3, R4, R5, R6, R7, R8, R9 and R10 are independently selected from the group consisting of hydrogen, halo, and organo radicals; and n is an integer having a value of from 1 to 4; and (ii) a silicone having at least one functionality which is reactive with a (meth)acryloxy functionality of said silyl di(meth)acrylate compound (C) a photoinitiator component; and (D) a moisture curing catalyst.
