Abstract
Abstract Amine silicate compounds are formed by the chemical reaction of hydrated silica with an amine compound in the presence of a suitable alkali catalyst at a suitably elevated temperature, and then by reacting the resultant compounds with aldehydes, epoxys, organic dicarboxylic anhydrides, polycarboxylic acid compounds or carbon disulfide, thereby forming a resinous condensation product.
