The said urea silicate is mixed with an aqueous formaldehyde solution in the ratio of 1:1 mols, heated to 70° to 100° C. while agitating, for 20 to 60 minutes, or until the desired viscosity is reached, thereby producing poly (formaldehyde urea silicate) resin, which is clear in color and may be produced as a thick liquid or as a solid.
