ABSTRACT:
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: (R13SiO1/2)w(R12SiO2/2)x(R1SiO3/2)y(SiO4/2)z, wherein each R1is independently selected from hydrogen, hydrocarbyl, substituted hydrocarbyl, —O═NR2R3, —OR2, —O—R4—OR2, and an epoxy-substituted organic group, wherein R2is C1to C8hydrocarbyl, R3is R2or —H, R4is hydrocarbylene, w+x+y+z=1, y/(w+x+y+z) is at least 0.67, and the siloxane resin has a softening point of from 30 to 115° C.; an agglomerate, and a method preparing the agglomerate.
