ABSTRACT:
A melamine-aldehyde resin is disclosed of a composition of melamine-aldehyde, a water-soluble, aliphatic diglycidyl ether, and water. The composition is cured to the A-stage and an absorbent sheet is impregnated with the resin which is then cured to the B-stage. At least one B-staged sheet is stacked with a postformable core stock and heated and pressed to form a C-staged postformable laminate. The laminate can be heated and pressed to postform it. The postformed laminate can be adhesively bonded to a substrate to form a counter top or other article.
