ABSTRACT:
The present invention relates to a novel composite adhesive used to adhere coating materials onto a substrate wherein the substrate material and the coating material have significantly different expansion properties, e.g., thermoplastic coating materials onto cellulose based substrate materials. The composite adhesive comprises both a rigid adhesive such as an epoxy or acrylic and a laminating adhesive such as a rubber based contact cement. In a preferred embodiment of the invention, a spline material is also rigidly adhered to the coating material so as to reinforce the bond between substrate and coating, especially where two pieces of coating material are attached at a seam. In another preferred embodiment the composite adhesive and/or spline material is used in preparing composite articles such as counters, sinks, furniture, profile edging, chemical resistant lab tops, showers, etc.
