Abstract

Machine elements having Release Coatings that are Electromagnetic Wave Energy Cured, Highly Abrasion Resistant, Flexible, Low Friction, Release Coatings for Compliant Elastomeric Substrates used on Bowed Rolls and Press Rolls. 100% solids, highly abrasion resistant release coatings which are polymerization cured with electromagnetic wave energy in the wave length range of 5500 .ANG. to 0.006 .ANG.. These coatings will bond securely to commonly used structural and elastomeric, rigid and flexible, substrates; including metallic and non-metallic materials. The coatings are compositions of varying percentages of 2-Phenoxyethyl Acrylate, Tetraethylene Glycol Diacrylate, Isobutyl Benzoin Ether, 1,6 Hexanediol Diacrylate, Cycloaliphatic Bis A Epoxide, Polyurethane Acrylate, Methyl Methacrylate, Polysiloxane and other Acrylics, Tertiary Amines, Epoxidized Novolac, Fluorinated Alkyloxylate, Electromagnetic Wave Energy sensitive Photoinitiators, and Electromagnetic energy absorbers. Multiple coating layers and multiple frequencies of wave energy are employed to cure the coatings in order to achieve optimum adhesion to substrates combined with optimum release, flexibility, hardness, low friction, and abrasion resistance of coatings. The useable electromagnetic wave lengths range from long wave ultraviolet down to short wave gamma rays (i.e. 5500 .ANG. to 0.006 .ANG.). Electron beam bombardment can also be used without photoinitiators.
