  • Patent number: 5919856
    Abstract: A water-based thermosetting coating composition comprises a polyester resin having a number of pendant carboxyl groups and a crosslinker for the resin both dispersed in an aqueous medium containing a neutralizing base. The polyester resin contains as polyester-forming polyhydric alcohol reactants from 1 to 40% by weight of the entire polyester-forming reactants of a polyalkadienediol or a hydrogenated products thereof and from 2 to 50% by weight of the entire polyester-forming reactants of a 2,2-bis(hydroxymethyl)alkanoic acid. The coating composition is useful for forming a multilayer coating film on metallic substrates such as automobile bodies by applying the coating composition as an intermediate coating layer between an electrodeposition coating layer and a top coating layer.

  • Patent number: 5830943
    Abstract: The invention relates to a process for the preparation of a modified polymer by reaction between a reactive polymer and at least a compound containing two or more functional groups. The polymer, which is solid at room temperature, is mixed, at a temperature at which the viscosity of the polymer is lower than 10000 dPas (measured according to Emila), with a compound containing two or more functional groups in a mixing means for achieving a homogeneous product and the mean residence time and the residence time distribution being chosen so that more than 50% of the reactive groups of the polymer has reacted.As means to make the composition homogeneous use is made of a static mixer.The functional groups of the compound containing two or more functional groups have different reactivities.The invention also relates to a binder composition, which comprises the modified polymer thus obtained and a crosslinker.

  • 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.
