Abstract
A process for producing a shelf-stable catalyst component for a room temperature vulcanizable silicone rubber composition comprising (a) mixing a organopolysiloxane fluid with first from 1 to 15 percent by weight of the total amounts of the following ingredients (1) an alkyl silicate cross-linking agent (2) a catalytic promoter which is a tin salt and (3) a self-bonding additive which is nitrogen-functional self-bonding additive until there is a uniform mixture; (b) adding to the mixture from 10 to 250 parts of filler and mixing the ingredients to a uniform mixture wherein the mixture is heated at a temperature of at least 100.degree. C. for at least 1 hour so as to drive off moisture and form a stable base mixture and then adding to the stable base mixture the rest of the cross-linking agent, the catalytic promoter and the shelf-bonding additive to form a self-stable uniform mixture.
