Abstract

Method for obtaining hydrolyzed ethyl silicate solutions used as a binding agent characterized by comprising a solution prepared by mixing an ethyl silicate with a silica content of the order of 39 to 43 percent by weight with 8 to 9 percent by weight of water in a mutual solvent and in the presence of a sufficient amount of an acid that is a catalyst for the hydrolysis of ethyl silicate, to give the final solution a pH of 1 to 3.
