Abstract: A composite substrate includes first and second substrate layers with a polyurethane foam layer there between. The foam layer preferably penetrates into the first and second substrate layers to form very strong bonds without the need for intervening adhesives. A component of the foam material formulation is natural oil. The resultant composite substrate thereby has excellent load-bearing properties. It can also be manufactured with lower cost capital equipment and a reduced impact on the environment relative to substrates using more conventional foam formulations and bonding processes.

Abstract: The present sprayable decorative coating material is composed of acrylic chips or gel coat chips that are mixed with polyurea and acrylic aqueous resins with special thixotropic material to produce a sprayable decorative coating for a solid surface. The present sprayable decorative coating material may be mixed with acrylic chips or gel coat chips. Different colored chips or mixtures of chips may be used to produce a wide array of finished decorative coating materials. The specific gravity of the resin of the chips is similar to the resin of the present sprayable decorative coating material, thus they are effectively suspended during mixing, spraying, and hardening, and may be applied to horizontal or vertical surfaces. The present sprayable decorative coating material uses a thixotropic compound that enables the resin mixture to be thin on shear when sprayed out of a low-pressure hopper gun, and the like.

Abstract: Low viscosity methacrylic-urethane oligomers useful as a styrene monomer substitute in unsaturated resin compositions, are prepared by reacting a hydroxy ethyl or propyl methyl methacrylate monomer with an elastomeric urethane prepolymer having free NCO groups.

Abstract: The invention features a polyamine epoxide adduct, prepared by admixing a source of epoxy group with a polyamine, and allowing the epoxy groups to react with the terminal amino groups of the polyamine so as to form the polyamine epoxy adduct. The polyamine epoxide adduct of the invention can be used as a component for preparing a polyurea polymer, thereby providing the resulting polyurea polymer with improved adhesiveness and greater chemical resistance to acidic conditions. Polyurea polymer coatings prepared from polyamine epoxide adducts demonstrate better chemical resistance and adhesion when applied to substrates than do conventionally prepared polyurea formulations.

Abstract: An 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, such as MDI, with an hydroxyl-containing acrylate monomer, such as a pentaerythritol triacrylate. The prepolymer composition contains 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 and a photoinitiator to promote the polymerization of the resin by exposure to radiant energy. The employment of the 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 photocured, unsaturated resin composition.
