摘要: A particulate foam control agent comprises 1 to 30 parts silicone antifoam, 70 to 99 parts zeolite carrier, 1 to 60% of the antifoam of an organopolysiloxane polyoxyalkylene copolymer, deposited onto the zeolite carrier not later than the antifoam and 1 to 40 parts by weight of a polycarboxylate-type binder or encapsulant. This combination give good release in early stages, storage stability and powder characteristics.
