Primerless Edge Banding

摘要

The present invention pertains to bonding an edge banding to the edge of wood or wood composite furniture by using a co-extruded dual compound polypropylene edge band that contains a main body of polypropylene and a primerless EVA backing layer. The edge of the wood or wood composite material is bonded to a polypropylene edge band by an EVA-based glue applied by an edge banding machine at the point of furniture manufacture. Bonding between the edge band and composite wood material is achieved without the use of a primer.

1. A method of applying an edge banding to a support surface without primer, comprising:
coextruding an edge band layer and an ethylene-vinyl acetate (EVA) backing layer such that a bond forms between the edge band layer and the EVA backing layer, forming a primerless edge banding; and applying an EVA-based glue to a support surface such that a bond forms between the EVA-based glue layer and the support surface; wherein the bonding between the EVA-based glue layer and the support surface is achieved without the use of a primer
