  • Silicone foam-suppressant compositions
    Patent number: 4486336
    Abstract: Silicone foam suppressant compositions are disclosed consisting essentially of a low viscosity polydimethylsiloxane and a high viscosity polydimethylsiloxane, a certain siloxane resin, and amorphous silica. These foam suppressant compositions can be used to suppress foam in both aqueous and hydrocarbon liquids. Advantageously, these foam suppressant compositions employ less of the resin and less amorphous silica than are normally found in silicone foam suppressants.
