HIGH POLYMER CONTENT SILICONE EMULSIONS

摘要

HIGH POLYMER CONTENT SILICONE EMULSIONS A polydiorganosiloxane emulsion having a combination of high polymer content and low viscosity can be produced by blending a high polymer content polydiorgano -siloxane macroemulsion, having a polymer content of greater than 60 percent by weight and an average particle size of greater than 0.14 micrometers ant a high polymer content polydiorganosiloxane microemulsion, having a polymer content of from 20 to 30 percent by weight and an average particle size of less than 0.14 micrometers, with the ratio of the average particle size of the macroemulsion to the average size of the microemulsion of from 5 to 15.
