Abstract

PURPOSE: To obtain a compsn. for an antifoaming agent having an excellent antifoaming effect and its sustaining characteristic by mixing organopolysiloxane having specific viscosity, an org. silicon compd. having a specific nitrogen-contg. substituent and fine powdery silica.
CONSTITUTION: Three components; for example, dimethyl polysiloxane (1,000cs viscosity having a hydroxyl group at both terminals of molecular chains as a component A, dimethyl bis(N-methyl acetamide) silane as a component B and fine powdery silica as a component C are mixed by an optional method, whereby a compsn. for an antifoaming agent is obtd. In the stage of use, in case a foaming system is oil type, it is diluted with an org. solvent, and in the case of aqueous type, it is emulsified with a surfactant and water or is used as a powdery antifoaming agent by using a surfactant and a protective colloid agent.
