SILICONE FOAM CONTROL COMPOSITIONS AND PROCESS FOR MAKING THEREOF

摘要

A silicone foam control composition comprises a finely divided filler, an organosilicon compound that contains at least two silicon-bonded hydroxy groups in each molecule, an organosilicon compound having at least two silicon-bonded aminoxy groups in each molecule, and optionally an inert fluid. At least (B) and (C) react so the silicone foam control composition has a viscosity of from 1,000 mPa·s to 1,000,000 mPa·s at 25° C. An oil-in-water silicone emulsion composition comprising the silicone foam control composition, a process for making the silicone foam control composition, and a method of using the composition, are also disclosed.
