Patent ID: 7994261

Claim:
A curable silicone composition which, when cured, exhibits an elongation of at least 150% and is capable of being painted without formation of fish eyes, the composition comprising a) about 50 to 95 wt % based on total polymer of at least one reactive organopolysiloxane polymer having a weight average molecular weight of about 10,000 to 200,000; b) about 1 to 10 wt % based on the weight of the organopolysiloxane of at least one silane functional crosslinker; and c) about 5 to 50 wt. % based on total polymer of a semi-compatible polymer component comprising one or more of the following polymers and oligomers: a silylated polyurethane, an MDI-terminated polyurethane, a reactive silylated polyol in which the polyol is at least one of polyester, polybutadiene and polycarbonate, a non-silylated acrylic polymer, and a silylated or unsilylated butyl functional polymer selected from styrene butadiene, polybutadiene and butyl rubber.
