Patent ID: 7737082

Claim:
A siloxane composition, comprising from 70 to 99 parts by weight of a solid particulate having a median particle size of from 0.1 to 3000 μm and from 1 to 30 parts by weight of a binder having a median particle size of from 5 to 250 μm, wherein the composition is a powder and the binder comprises a siloxane resin having the formula: (R 1 3 SiO 1/2 ) w (R 1 2 SiO 2/2 ) x (R 1 SiO 3/2 ) y (SiO 4/2 ) z , wherein each R 1 is independently selected from hydrogen, hydrocarbyl, substituted hydrocarbyl, —O═NR 2 R 3 , —OR 2 , —O—R 4 —OR 2 , and an epoxy-substituted organic group, wherein R 2 is C 1 to C 8 hydrocarbyl, R 3 is R 2 or —H, R 4 is hydrocarbylene, w+x+y+z=1, y/(w+x+y+z) is at least 0.67, at least 70 mol % of the groups R 1 in the siloxane resin are aryl, and the siloxane resin has a softening point of from 30 to 115° C.
