Abstract (en)
Release coatings are provided which 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 usable electromagnetic wave lengths range from long wave ultraviolet down to short wave gamma rays (i.e. 5500 ANGSTROM to 0.006 ANGSTROM ). Electron beam bombardment can also be used without photoinitiators. <IMAGE>
