Improved silicone foam control agent.

摘要

There are disclosed improved silicone foam control agents comprising (A) a high viscosity dimethylsilicone; (B) a low viscosity dimethylsilicone; (C) a silicone resin composed of (CH3)3SiO<1>/2 units and SiO4/2 units; and (D) amorhous silica. The improved foam control agents provide more foam (suds) controlling than silicone foam control agents previously known.
