Abstract
A low friction wear resistant coating for the base of a glass run channel and method. A thermoplastic powder is applied to a thermoset rubber substrate. The combination is heated to form free form shaped domains of thermoplastic on the thermoset rubber.
Claims9
A glass run weatherstrip comprising:
- a glass run channel having at least a portion thereof made of an ethylene propylene diene rubber;
- a discontinuous thermoplastic coating formed by a powder, high density polyethylene material having a molecular weight of from about 60,000 to about 200,000 heat fused directly to said ethylene propylene diene rubber material of said glass run weatherstrip for presenting spaced apart surfaces to a glass panel such that a low friction wear resistant surface having a coefficient of friction of from about 0.100 to about 0.200.
A glass run weatherstrip comprising:
- a glass run channel comprising an ethylene propylene diene monomer rubber and a discontinuous coating of a melted high density polyethylene material powder having a molecular weight of from about 60,000 to about 200,000 heat fused to said ethylene propylene diene monomer rubber thereof for forming free formed domains, thereby providing spaced apart surfaces on said weatherstrip for low friction wear resistant engagement with a glass window, thereby providing a surface having a coefficient of friction of from about 0.100 to about 0.200.
