Method of painting polyolefin substrate

Abstract

Abstract AN IMPROVED METHOD OF COATING A SOLID SUBSTRATE OF POLYOLEFIN WITH AN ADHERENT COATING OF A COPOLYMER OF ACRYLIC MONOMERS CROSSLINKED WITH VINYL MONOMERS WHICH COMPRISING APPLYING TO THE POLYOLEFIN SUBSTRATE A FILM-FORMING SOLUTION WHICH, ON A PIGMENT AND PARTICULAR FILLERFREE BASIS CONSISTS ESSENTIALLY OF 8A) ABOUT 15 TO ABOUT 45 WEIGHT PERCENT ACRYLATE SELECTED FROM THE GROUP CONSISTING OF DIACRYLATES AND DIMETHACRYLATES OF A C2-C12 A ALKANE DIOL, DIACRYLATES AND DMETHACRYLATES OF A C4-C12 POLYETHER DIOL, AND TRIACRYLATES AND TRIMETHACRYLATES OF A C6-C12 TRIOL, AND (B) 55 TO 85 WEIGHT PERCENT OF A VINYL RESINCOMPRISING COMPONENT CONSISTING OF 0 TO ABOUT 85 WEIGHT PERCENT MONOVINYL MONOMERS AND ABOUT 15 TO 100 WEIGHT PERCENT OF AN ALPHA-BETA OLEFINICALLY UNSATURATED COPOLYMER OF ACRYLIC MONOMERS CONTAINING BETWEEN ABOUT 0.5 AND ABOUT 5 UNITS OF ALPHA-BETA OLEFINIC UNSATURATION PER 1,000 UNITS MOLECULAR WEIGHT AND CROSSLINKING THE LIQUID COATING ON THE POLYOLEFIN SUBSTRATE BY EXPOSING THE COATING TO A BEAM OF POLYMERIZATION EFFECTING ELECTRONS HAVING AVERAGE ENERGY IN THE RANGE OF ABOUT 100,000 TO ABOUT 500,000 ELECTRON VOLTS.
