  • Weatherseal having a contact layer with thermoplastic particles in a thermoset carrier
    Patent number: 6406785
    Abstract: A weatherseal for repeatedly and releasably contacting a panel to provide a weather resistant seal therebetween. The weatherseal includes a substrate having a contact layer on the portion of the substrate that contacts the panel. The contact layer includes a multitude of surface treated ultra high molecular weight olefinic particles, such as ultra high molecular weight polyethylene, in a thermoset material such as cross linkable urethane, wherein some of the embedded particles define the area of contact between the weatherseal and the panel.
