STORAGE STABLE ORGANOSILOXANE COMPOSITION AND METHOD FOR PREPARING SAME
摘要
STORAGE STABLE ORGANOSILOXANE COMPOSITION AND METHOD FOR PREPARING SAME Storage stable and gel-free organosiloxane compositions in the form of flowable powders are prepared by blending a high consistency polydiorganosiloxane into a quantity of fluidized reinforcing filler that is heated to a temperature of from 100 to 200.degree.C. prior to or immediately following introduction of the polydiorganosiloxane. When silica is the reinforcing filler, the filler is typically treated with an anti-creping agent either prior to or during this blending process. The resultant mixture is heated while being subjected to shearing forces that reduce its average particle size to achieve a flowable powder.
