  • Siloxane composition, agglomerate, and method of preparing
    Patent number: 7737082
    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 ?m and from 1 to 30 parts by weight of a binder having a median particle size of from 5 to 250 ?m, 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 R1 is independently selected from hydrogen, hydrocarbyl, substituted hydrocarbyl, —O?NR2R3, —OR2, —O—R4—OR2, and an epoxy-substituted organic group, wherein R2 is C1 to C8 hydrocarbyl, R3 is R2 or —H, R4 is 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.
