An oil-resistant gasket material and packing material.

摘要

A product obtained by mixing the following ingredients is useful for gasket material or packing material with improved hot hydrocarbon oil resistance and improved adhesion: a linear polyorganosiloxane terminated with hydroxyl radicals or silicon-bonded organic moisture-hydrolyzable radicals, at least 0.5 percent on the average of the organic radicals being alkenyl radicals, and having a viscosity at 25 DEG C on the average of 0.0001 to 0.1 m<2>/s, filler, a silane or siloxane having per molecule at least one aminoalkyl radical bonded to silicon atoms through a silicon-carbon bond and at least one radical selected from alkoxy and aminoalkoxy, and a silicon-compound having per molecule at least three silicon-bonded organic moisture-hydrolyzable radicals, and optionally a curing-acceleration catalyst.
