Procedure
The said urea disilicate is added to an aqueous solution of formaldehyde, containing about 1.5 mols of formaldehyde, mixed, heated to 70° to 110° C. while agitating for 20 to 90 minutes or until the desired viscosity is obtained, thereby producing poly (formaldehyde urea disilicate) resin.
