Title:
STORAGE STABLE ORGANOSILOXANE COMPOSITION AND PREPARATION THEREOF
Document Type and Number:
Japanese Patent JP3149997
Kind Code:
B2
Abstract:
PURPOSE: To provide a storage stable and gel-free organosiloxane composition in the form of flowable powders.
CONSTITUTION: A desired composition is prepared by blending a high consistency polydiorganosiloxane into a fluidized reinforcing filler heated to 100-200°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 the blending process. The resultant mixture is heated while being subjected to shearing forces which reduce its average particle size to achieve a flowable powder.
