  • Weatherable building materials
    Patent number: 6589660
    Abstract: Weatherable building materials particularly well suited for entry door skins and other exterior building components are prepared by compression molding lignocellulosic fibers digested under conditions such that partial breakdown of hemicellulosic and other components produces an in situ binder, together with a secondary phenol/formaldehyde binder resin, followed by impregnating the product with a non-fugitive tertiary binder.
    Type: Grant

  • Weatherable coating and stain system for thermoset or thermoplastic composite surfaces
    Patent number: 6475615
    Abstract: A stain/topcoat system for non-porous thermoset and/or thermoplastic articles comprises a pigmented stain, and a topcoat comprising one or more non-siloxane film-forming polymers, an emulsion of one or more curable organopolysiloxanes, a weatherability agent having a functional group that is reactive with carboxylate functional sites and water. The topcoat displays exceptional adhesion and weatherability to pigmented stained surfaces.

  • Weatherable coating for stained composite thermoset or thermoplastic surface plastic building products
    Patent number: 6358614
    Abstract: A stain/topcoat system for non-porous thermoset and/or thermoplastic articles comprises a pigmented stain having substantially only a single binder resin which promotes adherence of a topcoat, and a topcoat which is an aqueous dispersion of a film forming polymer and a curable organopolysiloxane microemulsion. The topcoat displays exceptional adhesion and weatherability to pigmented stained surfaces.
