HIGH RELEASE COATINGS FOR PRINTING AND COATING ROLLERS

摘要

Coated rollers (10) with a hard, high release, non-marking, coating with excellent non-stick properties are disclosed for use as idler rollers, or as laminating, coating or printing rollers. The release coating comprises an outermost coat (15) which includes a silicone-epoxy emulsion in a water-based curing system that is sprayed or brushed on a roller core and then allowed to cure at room temperature. The release coating further comprises a primer coat (16) of silicone-epoxy in a water base that is also sprayed or brushed on the roller to form a coat and then allowed to cure at room temperature. Methods for making such rollers are also disclosed.
