Abstract
A process to prepare a glass run channel composite of the type utilized in vehicle applications for sealing against window glass, includes a cured elastomeric substrate having one or more sealing surfaces, and a polyolefin compound having a low melt index and a high density, and optionally containing a softening compound and other additives. The polyolefin compound is solvent-free and substantially melted when contacted with the sealing surfaces of the elastomeric substrate prior to cure, and upon cure of the elastomeric substrate, the polyolefin compound adheres to the substrate and provides a solid, low-friction abrasion-resistant coating on the sealing surfaces of the substrate for sealing against a window introduced into the glass run channel.
