Patent number: 10174179Abstract: 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.Type: GrantFiled: October 24, 2014Date of Patent: January 8, 2019Inventor: Ziqiang Lu

Patent number: 10119034Abstract: 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.Type: GrantFiled: October 6, 2016Date of Patent: November 6, 2018Inventor: Ziqiang Lu

The composition can also be used in water-based paint and coating systems. The composition according to the invention exhibits a synergistic improvement of the properties and, when used in relatively small amounts, constitutes highly effective water retention agents in such construction and paint systems, which also achieve outstanding air pore stability and tack.Type: GrantFiled: March 16, 2005Date of Patent: August 10, 2010Assignee: Construction Research & Technology GmbHInventors: Michael Schinabeck, Stefan Friedrich, Uwe Holland, Peter Gâberlein, Manfred Schuhbeck

Patent number: 7728055Abstract: An object of the present invention is to provide a new granulating process which can recover desired coagulated latex particles with a significantly excellent yield, and can suppress secondary coagulation under the condition having a higher temperature than a softening point of a polymer, without deteriorating the original quality of the polymer itself. A process for producing coagulated latex particles which can suppress the secondary coagulation under the condition having the broad temperature range, without deteriorating the original quality of the polymer itself by spraying or dropping a polymer latex into a gas-phase containing an inorganic salt and/or an acid, and a dispersant in an aerosol form, and dropping or feeding the droplets of the polymer latex into an aqueous phase containing a dispersant.Type: GrantFiled: July 12, 2006Date of Patent: June 1, 2010Assignee: Kaneka CorporationInventor: Takashi Ueda

Patent number: 7678456Abstract: An aqueous coating composition including a polyurethane polymer which contains carboxylic acid groups, a crosslinking agent, a wetting agent, a slip aid, and a UV stabilizing agent is provided. Coatings prepared from the aqueous coating composition are durable and have low surface friction, flexibility at low temperatures, and adhesion to low surface energy substrates. A method of preparing a substrate coated with the aqueous coating composition and an article containing the coated substrate are also provided. The aqueous coating composition is useful for providing a protective coating with a low friction surface for automotive weatherstrip.Type: GrantFiled: January 25, 2006Date of Patent: March 16, 2010Assignee: Rohm and Haas CompanyInventor: Donald Thomas Robertson

Publication number: 20090306254Abstract: Paint formulations that exhibit improved performance characteristics due to the presence of a combination of a cellulose ether (carboxymethylcellulose and/or hydroxyethylcellulose) and a network building polymer (gellan gum, carrageenan, etc., as examples) as a thickening system therein are provided. Such a combination permits long-term shelf stability of the paint formulation while simultaneously according effective flow, leveling, and other important properties to the final paint formulation. The combination of the cellulose ether and a network building polymer allows for a lower viscosity cellulosic compound to impart the desired rheological behavior therein while also permitting the other desirable characteristics noted above. Such paint compositions also exhibit improved atomization for spray applications with such a thickening system.Type: ApplicationFiled: August 17, 2009Publication date: December 10, 2009Applicant: CP KELCO U.S., INC.Inventors: Maarten van der Wielen, Phil Winston, John Swazey, Ross Clark, Maarit Lahtinen
