<p>The scuff-resistance of a high-pressure laminate is improved by incorporating in or very near the surface thereof, finely divided polyethylene wax preferably having a particle size of about 1-25 microns and a melting point of 220 DEG -230 DEG F. The wax is incorporated as part of a coating mixture applied to the face of an unimpregnated decor paper sheet in an ultra-thin layer, which layer is dried at atemperature below the wax melting point and then impregnated with conventional melamine-formaldehyde resin. The impregnated sheet is placed onto a sheet of convention phenolic resin impregnated core sheets and consolidated in the conventional way under heat and pressure. During consolidation, the wax particles "bloom", or migrate to the surface. The finished laminate surface has greatly improved scuff-resistance.</p> |
