ABSTRACT:
A method is provided for top-coating a veneered substrate. Heat-activated urethane adhesive layers are placed on opposing sides of a veneered substrate, and Lexan films of equal thickness are placed adjacent the two layers of adhesive. A polyethylene sheet is placed adjacent each Lexan film to act as a release masking. A silicone pad is laid on the lower platen, and a 5 mil polycarbonate sheet is placed on top of the stack for contacting the top platen of the laminating press. The laminating press then applies heat and pressure for a predetermined period of time to produce a hard-coated veneered substrate, and the polyethylene sheets are discarded.
