LOW TEMPERATURE LAMINATION OF WOOD

摘要

Storage stable and nonblocking adhesive films and processes for adhering decorative overlays such as wood veneers, high pressure laminates, and thermoplastic overlays to wood substrates. The adhesive films contain a base adhesive comprising an ethylene polymer having carboxylic acid functionality or an ethylene polymer capable of being modified to have carboxylic acid functionality. Preferred adhesive films further comprise a crosslinking agent such as an epoxy. The adhesive films may further comprise compatibilizers and/or curing agents. The adhesive films allow decorative overlays to be laminated at lower temperatures than prior art adhesive systems and demonstrate superior melt strength. The adhesive films and processes of the present invention can be advantageously utilized in applications such as furniture laminates, cabinet door laminates, flooring laminates, residential and architectural door skin laminates, store fixtures, high pressure laminates for countertops, veneer laminated sheet, and plywood fabrication.
