Abstract (en)

[origin: WO9710102A1] 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 (PTFE) skin (18) that has a porous surface (20) attached to a substratum (16) and an impermeable surface (22) exposed to the contact surface, in which the PTFE is filled with a particulate filter. This use of dual surfaces on a single thin coating provides both an excellent bond to substratum materials, such as silicone elastomer layer, as well as being highly wear resistant to chemical attack.
