Dispersed particles of a fluorine rubber composition containing silicone material cured.

摘要

PURPOSE:To obtain a fluororubber composition having excellent rolling workability before curing and excellent adhesiveness to various substrates after curing by blending fluororubber with specific amounts of a specific cured silicone material and a specific organoalkoxysilane. CONSTITUTION:(A) 100pts.wt. fluororubber is blended with (B) 0.1-30pts.wt., preferably 1-15pts.wt. cured silicone material having =100mum average particle diameter, (C) 0.1-30pts.wt., preferably 0.5-15pts.wt. (preferably 0.01-2pts.wt. based on 100pts.wt. component B) epoxy group-containing organoalkoxysilane (e.g, gamma-glycidoxypropyltrimethoxysilane) or partial hydrolyzate there of and (D) a curing agent.
