  • Publication number: 20100069533
    Abstract: The present invention provides wood adhesive binder compositions comprising a naturally occurring protein component, e.g. soy flour, and an oxazoline-functional group containing polymer or resin component, the two components in a solids weight ratio of from 60:40 to 98:2. As formulated, the compositions may comprise from 40 to 98 wt. % of the naturally occurring protein component, preferably, 50 wt. % or more. Preferably, the wood adhesive binder further comprises lignins or lignosulfonate. Where the wood adhesive binder compositions comprise lignins or lignosulfonates, they remain more fluid and workable at a higher pH such as, for example, 4.5 or more. Any of the compositions may be formulated with one or more in situ acid generator compound to insure more rapid cure on heating or pressing. The binder enables the provision of mechanically sound, low cost and biodegradable composites, such as, medium density fiberboard (MDF).

  • Patent number: 7579289
    Abstract: According to the present invention, water repellant curable compositions comprise: (i) one or more polyacid; (ii) one or more polyol comprising at least two hydroxyl groups; (iii) one or more reactive waterproofing agent chosen from a C5 to C30 alk(en)yl monocarboxylate of a (poly)ethoxylated trihydric polyol, C5 to C30 alk(en)ylamine (poly)alkoxylate, C5 to C30 alk(en)yl diamine (poly)alkoxylate, C5 to C30 alk(en)ylamine (poly)alkoxylate containing an ether or thiother group in the alk(en)ylamine group, and mixtures thereof. The compositions are dilutable with water to make thermosetting aqueous binder compositions. The present invention also provides methods of treating or contacting substrates chosen from a non-woven, woven and a composite, such as glass fiber substrates, with the thermosetting aqueous binder compositions, and drying and curing, and the water resistant products produced thereby.

  • Publication number: 20090156078
    Abstract: The present invention provides flexible binder compositions comprising one or more polycarboxy emulsion copolymer has a measured Tg of 40° C. or less, such as from ?45° C. to 25° C., and a polyol crosslinker. In one embodiment, the binder compositions comprising the polycarboxy emulsion copolymer can be used in making pultruded composites, such as sheets, for example, flexible gypsum board facing sheets, and flexible non-woven articles such as, for example, carpet backing.

  • Publication number: 20080114132
    Abstract: The present invention provides powder compositions for making coatings or films comprising one or more film-forming polymer or resin and one or more ?-hydroxyalkyl amide curing agent chosen from ?-hydroxyalkyl amide curing agents made from the reaction of one or more lactone or lactide with one or more alkanolamine compound containing one or more ?-aminoalcohol, oligomeric ?-hydroxyalkyl amide curing agents made from the reaction of one or more mixture of aromatic anyhydride with aliphatic anhydride with one or more alkanolamine compound containing one or more ?-aminoalcohol, mixtures thereof, and mixtures thereof with one or more tetrafunctional ?-hydroxyalkyl amide curing agent. The present invention enables the reduction of defects in coatings and films, especially in the case of coatings and films 75 ?m or thicker, and, further, provides coating powders that are less expensive than coating powders that are cured solely with tetrafunctional ?-hydroxyalkyl amides.

  • Patent number: 5534310
    Abstract: A latex binder suitable for producing high gloss coating on weathered substrates and a method for producing such coatings. The binder includes a low molecular weight and low acid number latex polymer having an acid functional and an enamine functional moiety that results from the reaction of ammonia or amine with an acetoacetyl functional pendant moiety on the latex polymer. A film containing the latex binder is applied on a substrate and then exposed to ambient light and air to produce a high gloss highly adherent film on difficult to adhere surfaces, such as weathered chalky substrates.

  • Patent number: 5385960
    Abstract: Coatings compositions including stable composite latex-pigment particles are prepared by dispersing titanium dioxide pigment particles in a first aqueous medium and preparing a dispersion of selected polymeric latex particles, which have at least one dihydrogen phosphate functional group, in a second aqueous medium. The media are mixed and the selected polymeric latex particles adsorb on the titanium dioxide particles. Dibasic phosphate is then provided to the mixture to stop adsorption and stabilize the composite particles. The coating composition gives a coating with improved hiding.

  • Patent number: 4019576
    Abstract: This invention relates to the recovery of oil from an oil well which normally produces a mixture of oil and water. The invention is carried out by determining the potential free water level in the well bore, draining the oil gravitationally from a point above the predetermined water level, and withdrawing the drained oil.
