ABSTRACT:
A flexible, fully cured, resin-impregnated sheet material useful as a surface-covering laminate product, particularly on particle boards, and the process of preparing such sheet material and the laminate product, which sheet material is prepared by providing a thin, fibrous sheet material impregnated with a curable, thermosetting resin; applying onto one surface of the resin-impregnated sheet material a layer of a compatible resin adhesive material; and subjecting the resin-impregnated coated sheet material to high pressures of over about 20 kilos per centimeter square at a resin-curing temperature for a period of time to provide a thin sheet material characterized by a nonporous, cured, resin-rich, face surface free of adhesive, and an adhesive-rich back surface, the sheet material being flexible and capable of being handled without fracture thereof. The flexible sheet material is secured by adhesively bonding the material to a substrate, such as a particle board, for use as a surface covering.
