ABSTRACT:
The present invention is an improved release coating for use on a variety of elastomeric structures, such as printer rollers and belts. The coating of the present invention is a thin expanded polytetrafluoroethylene skin that has a porous surface attached to a substratum and an impermeable surface exposed as the contact surface. This use of dual surfaces on a single thin coating provides both an excellent bond to substratum materials, such as a silicone elastomer layer, as well as being highly wear resistant and resistant to chemical attack.
