Abstract
A combination comprising a substrate and cured coating composition formed of the hydrolysis product of an epoxy functional alkoxy silane in combination with one or more monoaromatic (mono- or di) glycidyl ethers, the cured coating providing improved adhesion as compared to previous known UV curable coatings. The coating composition includes at least one monoaromatic di- or monoglycidyl ethers, and most preferably includes resorcinol diglycidyl ether.
Claims20
A combination comprising a substrate having a cured coating formed by the application of ultraviolet radiation to an organofunctional silane composition that comprises a monoaromatic mono- or diglycidyl ether, wherein the cured coating exhibits acceptable adhesion resistance, as determined by crosshatch adhesion testing under conditions of deionized water and humidity testing.
