Edging material for application to the edges of substrates
Abstract
Abstract A DECORATIVE, FUNCTIONAL EDGING MATERIAL FOR APPLICTION TO THE EDGES OF PANELS OR SUBSTRATES. THE EDGING MATERIAL IS A POLYESTER RESIN IMPREGNATED PAPER SHEET COATED ON THE BACK SIDE WITH A HIGH VISCOSITY THERMOSETTING HOT-MELT GLUE. THE BASE OF THE EDGING MATERIAL IS A SINGLE SHEET OF PAPER, PREFERABLY AN ALPHA CELLULOSE OR KRAFT SATURATING PAPER HAVING A BASIS WEIGHT OF AT LEAST 65 POUNDS, IMPREGNATED WITH A POLYMERIZABLE UNSATURATED POLYESTER RESIN. THE HOT-MELT GLUE IS AN ETHYLENE-VINYL ACETATE COPOLYMER, HAVING CERTAIN DEFINITE CHARACTERISITCS WHICH ENABLE THE EDGING TO ECOME PERMANENTLY BONDED TO THE EDGE PANEL SURFACE UNDER TEMPERATURE AND PRESSURE. THE SHEET, IMPREGNATED WITH A POLYMERIZABLE POLYESTER RESIN, IS SUITABLY CURED TO GIVE A NON-CRACKING EDGING MATERIAL, COATED WITH THE HOT-MELT GLUE, AND CUT INTO STRIPS OF SUITABLE WIDTHS AND WOUND INTO ROLLS.
