  • Patent number: 11807782
    Abstract: A novel method of improving the water and leaching resistances and durability of a fire retardant-treated wood product by using a chemical fire retardant composition in which crosslinking polyvinyl acetate (XPAVc or X-PVAc) is applied as a protective coating on wood over the fire retardant layer. An additional crosslinking polyvinyl acetate coating layer or one or more layers of acrylic, alkyd, epoxy, lacquer, polyester, polyurethane, silicone coatings, vinyl ester, or the like may further cover the cured crosslinking polyvinyl acetate primer and then dried or cured.

  • Patent number: 11046370
    Abstract: An example reinforced wood flooring for use in forming a truck trailer or container floor may include a wood member. The wood member may include a plurality of wood strips that are attached together. The wood member may also have a top surface and a bottom surface. An essentially water impermeable fiber-reinforced thermoplastic underlay may be adhered to the bottom surface of the wood member.

  • Publication number: 20200217010
    Abstract: A natural strip or strip-based weaving or weave fabric product or a natural strip or strip-based woven product is coated and protected with a crosslinking polyvinyl acetate (XPVAc or x-PVAc) adhesive. Said adhesive is applied and cured on the exterior surfaces of said product as a first coating layer or a primer in combination with a coating layer of acrylic, alkyd, asphalt, epoxy, latex, polyurethane, silicone coatings, urethane, vinyl ester, etc. coated over the cured adhesive as a second coating layer or a topcoat. Said product is woven or fabricated with stalks, stakes, staves, stems, sticks, strands, shoots, splints, straws, strings, twigs, bark, branches, laths, leaves, rods, roots, whicker, etc. of a fiber plant, a tree, or a crop, or the combination thereof.

  • Publication number: 20190309173
    Abstract: A natural fabric or textile product is coated and protected with a waterproofing composition comprising a crosslinking polyvinyl acetate (XPVAc or x-PVAc) emulsion polymer or adhesive applied and cured as a first coating layer or a primer and a coating layer of acrylic, alkyd, asphalt, emulsion polymer isocyanate, epoxy, lacquer, latex, polyurethane, urethane, or vinyl ester coated over the cured crosslinking polyvinyl acetate as a second coating layer or a topcoat. The natural fabric product is fabricated by weaving, knitting or felting the fibers, yarns or threads of vegetable or plant fibers from cotton, sisal, kenaf, hemp, jute, flax, reed, sugarcane, ramie, henequen, raffia, nettle, milkweeds, palm, coir, grass, Spanish moss, New Zealand flax, kapok, sugarcane, bamboo, or wood, or those of the protein fibers from wool, silk, spider threads, sea silk, or the combination thereof.

  • Patent number: 10174179
    Abstract: The invention provides a novel product and method to coat wood and wood composite products and improves their durability and service life in outdoor conditions. The method comprises coating a Type I waterborne adhesive, crosslinking polyvinyl acetate (XPVAc or x-PVAc), on wood and applying sufficient heat to dry and cure the coating to form a durable bond on wood or wood composites. The above paint system consists of at least two coating layers, in which both layers are crosslinking polyvinyl acetate coating. Alternatively, crosslinking polyvinyl acetate can be used as a primer, while the second or the third layer uses an acrylic, alkyd, or other water resistant coating. This coating approach results in a durable wood or wood composite product due to the excellent bonding with the wood substrate and the excellent water blocking by crosslinking polyvinyl acetate.

  • Patent number: 10119034
    Abstract: A crosslinking polyvinyl acetate (XPVAc or X-PVAc) adhesive is applied as a primer (i.e., a basecoat) or an exterior coat (i.e., a top coat) on a wood preservation product which is mainly treated with a water-based preservative. By sealing the exterior wood surfaces, the new coating system not only effectively prevents the leaching of the preservative by bonding and chelating with the unfixed preservative compounds or complexes at the surface layer, but it also significantly reduces surface aging of wood, maintains effective preservation functions, and provides a longer service life to the wood preservation product.
