Abstract
The invention provides a novel organopolysiloxane-containing aqueous emulsion composition which, upon removal of water by drying at room temperature, can give a cured rubbery elastomer having excellent mechanical properties and exhibiting strong adhesion to the substrate on which it has been cured. The inventive composition is prepared by blending (A) an aqueous emulsion of an organopolysiloxane having silicon-bonded hydroxy groups and emulsified in water by use of an anionic surface active agent, (B) a mixture of a reaction product of a carboxylic acid anhydride with an amino-functional organosilane and a colloidal silica in the form of an aqueous suspension and (C) a curing catalyst in limited proportions.
