摘要:A defoamer composition is obtained when a mixture of certain siloxane-containing components, a finely divided filler, a reaction catalyst and at least onecompound having in each molecule at least 1 group expressed by ≡COR⁵, -COOR⁶ or -(OR⁷)- is heated. R⁵ and R⁶ are the hydrogen atom or saturated or unsaturatedmonovalent hydrocarbon groups, R⁷ is a divalent hydrocarbon group having two to sixcarbon atoms, and the average value of is ≧1. The siloxane-containing componentscomprise resinous polyorganosiloxanes and typically, polydiorganosiloxanes. The heatedmixture is useful for defoaming anionic systems.
