Patent ID: 7452937

Claim:
A room temperature vulcanizing silicone polymer composition, which includes: a) as part of the silicone polymer, a segment comprising a silicone polymer of Formula (I): wherein n is about 20 to about 2,400; R in each occurrence may be the same or different and is a C 1 to C 10 hydrocarbon radical; R 1 in each occurrence may be the same or different and is a C 1 to C 10 hydrocarbon radical; and X is a member selected from the group consisting of O, NR 3 , S(O) m , and P(O) r , wherein m is 0, 1, or 2, r is 1 or 2; R 3 is a member selected from the group consisting of C 1 to C 4 alkyl, C 1 to C 4 alkenyl, and C(O)R 6 , wherein R 6 is a member selected from the group consisting of C 1 to C 4 alkyl, C 1 to C 4 alkenyl, and C 1 to C 4 alkoxy; and b) an inorganic filler present in an amount of at least about 15% by weight of the total composition, wherein: i. at least about 90% of the inorganic filler has a diameter less than 2 microns; ii. at least about 65% of the inorganic filler has diameter less than 1 micron; and iii. the inorganic filler has an average particle diameter from about 0.2 to about 2.0 microns.
