Abstract
A method for making a cured rubber sheet, the method comprising providing an uncured rubber sheet, where the uncured rubber sheet includes opposing planar surfaces, applying a curable coating composition to one planar surface of the sheet to form a layer of curable coating composition, subjecting the curable coating composition to curing conditions that cure the coating composition and thereby form a cured coating layer on the uncured rubber sheet, rolling the uncured rubber sheet having a cured coating layer onto itself to form a roll, and subjecting the roll to curing conditions that cure the uncured rubber sheet and thereby forms a roll of cured rubber sheet.
