UV curable elastomer composition

A thermally stable, UV curable elastomer composition comprising

• A) 70 to 99 weight percent of a fluoroelastomer having at least one cure site selected from the group consisting of 1) copolymerized brominated olefins, chlorinated olefins and iodinated olefins;
• 2) copolymerized brominated unsaturated ethers, chlorinated unsaturated ethers, and iodinated unsaturated ethers;
• 3) copolymerized non-conjugated dienes and trienes and 4) iodine atoms and bromine atoms and mixtures thereof that are present at terminal positions of the fluoroelastomer chain;
• B) 0.5 to 20 weight percent of a multifunctional crosslinking agent selected from the group consisting of multifunctional acrylic crosslinking agents, multifunctional methacrylic crosslinking agents, multifunctional cyanurate crosslinking agents, and multifunctional isocyanurate crosslinking agents;
• and
• C) 0.1 to 10 weight percent of a UV initiator wherein the weight percentages of each of components A), B), and C) are based on the combined weight of components A), B), and C).
