  • Patent number: 6657002
    Abstract: The present invention is directed to a polyester carboxylate polymeric pigment dispersant to be used as a grind resin to incorporate inorganic pigment into a pigment dispersion for a coating composition. The polymeric pigment dispersant is the reaction product of pentaerythritol, hexahydrophthalic anhydride, glycidylneodecanoate, and dimethylethanolamine. The present invention is also directed to a method of preparing the polymeric pigment dispersant. In this method, the pentaerythritol and the hexahydrophthalic anhydride are polymerized to form an intermediate compound. Next, an epoxy group of the glycidylneodecanoate reacts with the intermediate compound, and then the dimethylethanolamine neutralizes the intermediate compound to form the completed polymeric pigment dispersant. The polymeric pigment dispersant is utilized for efficient wetting and grinding of the pigment.

As a result, the plastic is melt-extruded and mixed with the coloring agent and subsequently subjected to solid stating wherein the base polymer is accorded an increase in molecular weight and the coloring agent becomes integrated therein. Such a method permits avoidance of introduction of a coloring agent to the polymerization reaction chamber that results in extensive staining (particularly upon a change of desired colors for the next batch of plastic). Such a method also permits avoidance of the introduction of a coloring agent to an injection molding process that results in uneven color dispersion and sub-optimal physical properties within the ultimate article.

    Abstract: By combining alkali earth oxide aluminate phosphors with an alkyd base, a rheology improver, another pigment, an anti-skin additive, and other ingredients, one can achieve a luminescent paint that has characteristics including tintability, applicability, viscosity, appearance and coloration comparable to a non-luminescent paint, with adequate protection from moisture and at a relatively reasonable cost. An alkyd base formulation is the preferred formulation that will allow for the highest amount of loading without compromising the quality of the paint with respect to appearance or applicability. The appearance of the paint in daylight has minimal orange peel or pockmark affects because of the ability of this formulation to suspend and diffuse the large luminescent particles effectively while applying the product. In addition because of the effectiveness of this formulation the appearance of the glow is even, consistent and undisrupted in a properly installed scenario.

  • Patent number: 6333370
    Abstract: A binder for a coating composition is obtainable as the reaction product of a carboxyl-terminated fatty acid ester with an ethylenically unsaturated carboxylic acid and an ethylenically unsaturated carboxylic acid ester. The carboxylic fatty acid ester is produced by reaction of an autoxidisable fatty acid and a polyol, with modification to introduce at least one terminal carboxyl group. The reaction is optionally effected in an organic solvent which is substantially removed at the end. The material is neutralized with a base to render it water-soluble. Thixotropy can be endowed by an amine/(poly)isocyanate final reaction stage to prior neutralization.

  • Patent number: 6306956
    Abstract: The present invention is directed to an aqueous dispersion of a polyester salt and polymeric vehicles which include the aqueous dispersions of a polyester salt. The polymeric vehicle is particularly effective for providing coating binders in cured primer coatings. The primer coating compositions are useful for multilayer paint coating films which have at least two layers of paint film including the cured primer coating composition film. The use of the primer polymeric vehicles of the present invention in conjunction with one or more additional overlaying top coating film layers provide a multiple layer coatings having improved adhesion and chip resistance.
