Reaction Steps
About 120 parts by weight of a 37% aqueous solution of formaldehyde is added to said granules of melamine silicoformate and melamine metasilicate and then heated to 70° to 120° C., while agitating, for 20 to 120 minutes, thereby producing a white resin, poly (formaldehyde melamine silicoformate and metasilicate). The said resin is soluble in acetic acid, softens with heat, and may be molded into useful objects.
