  • Patent number: 11273623
    Abstract: A composite panel includes a mold surface, a layer of gel coat applied to the mold surface, a wet laminate containing a resin applied to the layer of gel coat, a substrate of lauan or another moisture-carrying or moisture-absorbing material placed on the wet laminate, and a layer of a bonding promoter provided at the interface of the substrate with the wet laminate, additional to any amount of promoter(s) present in the resin of the wet laminate. Without previously curing or drying the layer consisting essentially of the bonding promoter in the solvent, each of the wet laminate, the bonding promoter, and the gel coat are simultaneously cured.

  • Patent number: 8232347
    Abstract: A high-quality oxygen-absorbing resin composition which is obtained without suffering resin scorching. Also provided are pellets for the oxygen-absorbing resin composition which comprise a thermoplastic resin (A) and an oxidation catalyst. After the pellets are mixed with a trigger resin and a thermoplastic resin (C), the trigger resin functions as a trigger to cause the oxidation of the thermoplastic resins (A) and (C) to proceed. As a result, the resultant composition absorbs oxygen.

  • Patent number: 5773531
    Abstract: A modified acrylic urethane prepolymer composition and an unsaturated polyester resin composition to which the prepolymer has been added. The prepolymer composition includes an acrylic urethane prepolymer prepared by the reaction of diisocyanate, like MDI, with an hydroxyl-containing acrylate monomer, such as a pentaerythritol triacrylate, which prepolymer composition may contain a styrene monomer and an inhibitor, such as benzoquinone, to retard the reaction of the prepolymer and styrene monomer prior to the addition of the prepolymer composition into the polyester resin composition. The employment of the modified urethane prepolymer composition provides for the reduction in the amount of styrene monomer used in the unsaturated resin composition and also provides for improved chemical and physical properties of the cured, unsaturated resin composition, such as a reduction in glass roll-out when the resin composition is employed with fiberglass.

  • Patent number: 4321332
    Abstract: This invention relates to a process of preparing aqueous slurries of vesiculated granules of crosslinked polyester resin wherein the granules have a maximum shrinkage on drying of 5% of the granule diameter. Previously-known processes for the preparation of granules of this type have utilized polyamines; this has led to odor and color problems. These problems may be eliminated or substantially reduced by the use of bases which are metal oxides, hydroxides or salts wherein the metal cation is selected from Ca, Mg, Ba, Ti, Zn, Pb, Sr and Co and, when a metal salt is used, the pKa value of the conjugate acid of the anion is greater than 2. The resulting granules are useful at matting and opacifying agents in, for example, paint compositions.

    Abstract: Gel-time drift may be reduced in promoted polyester resin systems by incorporation of an amine salt in accordance with the disclosed compositions and methods. The amine salt is a salt-like reaction product of an amine and a carboxylic acid-containing moiety. For free-amine type promoted resin systems, an amine salt may be substituted for the amine promotor to provide a low-energy curable polyester resin system having the advantages of a promoted system as well as being stabilized against gel-time drift. Comparative data show suppression of gel-time drift of resin samples containing an amine salt to as low as 7 percent of gel-time drift of counterpart free-amine promoted resin system samples.
