Patent ID: 7803358

Claim:
A siloxane resin composition obtained by mixing: A) a MQ resin comprising at least 80 mole % of siloxy units selected from (R 1 3 SiO 1/2 ) a and (SiO 4/2 ) b units, where R 1 is independently an alkyl group having from 1 to 8 carbon atoms, an aryl group, a carbinol group, or an amino group, with the proviso that at least 95 mole % of the R 1 groups are alkyl groups, a and b has a value greater than zero, and the ratio of a/b is 0.5 to 1.5; B) a propyl silsesquioxane resin comprising at least 80 mole % R 3 SiO 3/2 units, where R 3 is independently an alkyl group having from 1 to 8 carbon atoms, an aryl group, a carbinol group, or an amino group, with the proviso that at least 40 mole % of the R 3 groups are propyl, and optionally; C) a volatile siloxane or organic solvent, wherein the weight ratio of component A to B is from 90:10 to 10:90.
