耐火性シーラント組成物
Document Type and Number:
Japanese Patent JP4615732
Kind Code:
B2
Abstract:
Curable liquid silicone rubber compositions that are curable to form silicone elastomers which are useable as fire resistant sealants. These compositions have low heat release and form hard chars on burning, and comprise:(A) a liquid polyorganosiloxane polymer described by the formula where each R1 is independently selected from the group consisting of alkyl, alkenyl, aryl, and halogenated alkyl groups having from 1 to 18 carbon atoms, each R2 is independently selected from the group consisting of hydroxyl, alkoxy, alkenyl, and alkynyl groups, and x is an integer having a value of from about 10 to 1500,(B) a cross-linking organosilicon compound having at least 3 silicon-bonded reactive groups,(C) a catalyst capable of promoting the reaction between the silicon-bonded R2 groups of Component A and the silicon-bonded reactive group of Component B,(D) wollastonite, and(E) an optional reinforcing filler.
