A process for making a silicon resin includes the steps of substantiallyncontinuously polymerizing sodium silicate in an aqueous medium and in thenpresence of acid to form a silica hydrosol, substantially continuouslynquenching the silica hydrosol with alcohol and substantially continuouslyncapping the quenched silica hydrosol in a reaction mixture comprising waternand an organic solvent, siloxane fluid or mixture thereof with an organosiliconncapping compound to form the silicon resin. |
