Method of producing a silicone defoamer composition |
摘要 |
Foam control compositions are prepared by reacting a mixture of components which include a polyorganosiloxane fluid bearing one or more hydroxyl and/or hydrocarbonoxy groups, a resinous siloxane or a silicone resin-producing silicon compound, a finely divided filler material and a catalyst to promote the reaction of the listed components. The compositions can optionally contain a polyorganosiloxane fluid which is substantially free of reactive groups and/or a polyorganosiloxane fluid bearing two or more hydroxyl and/or hydrocarbonoxy groups.
