CA 2289310
A system and method for substantially permanently bonding decorative laminates to a polymeric or other alternative substrate material are disclosed. A preferred embodiment of the present invention utilizes a corona treater to increase surface tension of surfaces of a substrate material in order to provide for improved adhesive bonding. Thereafter, a film of adhesive is applied to the surfaces to be mated with laminates, the laminates are mated with the substrate surfaces having the adhesive film, and pressure is applied during curing of the adhesive. Precise control of parameters such as the thickness of the adhesive, the amount of catalyst introduced, the amount of pressure applied during curing, the duration of the application of pressure, the amount of heat present during curing, and the like, allows operation of the present invention to provide a suitably permanent bond between dissimilar materials such as high pressure decorative laminate, ABS polymeric substrate, and high pressure laminate backer.
