Abstract: An automotive refinish coating composition having a volatile organic content not exceeding 3.0 pounds per gallon contains a hydroxyl functional polyester and a polyisocyanate curing agent. The hydroxyl functional polyester is prepared from reactants containing:A. from about 15 percent to about 50 percent of a polyol or mixture of polyols, each having a formula molecular weight from about 50 to about 2,000;B. from about 15 percent to about 50 percent of a long chain monocarboxylic acid or mixture of such acids, each having from about 6 to 24 carbon atoms; andC. from about 15 percent to about 30 percent of 1,4-cyclohexane dicarboxylic acid; the percentages based on the total weight of reactants used in preparing the polyester. The refinish coating composition is particularly suitable as a clear topcoat over a pigmented basecoat.

Abstract: Disclosed is a curable filler composition which resists absorption into a porous substrate, particularly one derived from wood, comprising: (1) a liquid, ungelled binder of an unsaturated polyester resin having number average molecular weight of from 500 to 3,000 derived from an ethylenically unsaturated carboxylic acid or anhydride thereof, the unsaturated polyester resin having been reacted with a hydroxyl-containing amine selected from the group consisting of an alkanol amine having a secondary amino group, an alkanol amine having a primary amino group and a mixture thereof, (2) one or more ethylenically unsaturated compounds different from and cocurable with the unsaturated polyester resin, (3) pigment, (4) a free radical initiator, and (5) optionally a carrier solvent for the filler composition.Disclosed is a method of minimizing absorption of a filler composition into a warm or hot porous substrate.

Abstract: A liquid, ungelled composition of matter composed of a graft copolymer prepared by the free radical initiated polymerization in an organic medium of a vinyl monomer component which contains at least 0.5 weight percent of an epoxy group containing vinyl monomer in the presence of an acid group containing polymer having an acid value greater than 10 mg KOH/g. One means of graft formation is the condensation reaction between the acid groups of the acid group containing polymer and the epoxy groups of the vinyl monomer component.

Abstract: Coating compositions which may be applied by conventional techniques as well as by electrodeposition are provided by reacting a polyglycidyl ether of a polyphenol with an amino acid containing at least one amine group and one carboxyl group, wherein the amine group of the acid is preferentially reactive with the epoxy groups of the polyglycidyl ether. The resultant product can then be solubilized by neutralizing at least a portion of the acid functionality thereof with an amine or other base. Especially useful amino acids are the aminobenzoic acids.

Abstract: Metal containers suitable for packaging beer and other beverages have as the internal sanitary liner a film of a water-based coating composition prepared by dissolving or dispersing in aqueous medium an at least partially neutralized reaction product of a polyepoxide having a 1,2-epoxy equivalency greater than 1.0 and an amino acid containing at least one amine group and at least one carboxyl group, wherein the amine groups of the amino acid are preferentially reactive with the epoxy groups of the polyepoxide, and a curing or cross-linking agent. These compositions provide containers with cured liners which do not impart undesirable turbidity or taste characteristics to the beer, soft drinks or fruit juices packaged therein.

Abstract: Esters of glycidyl polyethers of saturated phenols are especially useful in coating compositions having a low organic solvent content. The esters are the reaction products of from about 0.5 to about 1.5 equivalents of a saturated monocarboxylic acid with each epoxy group in a diglycidyl polyether of phenols where the aromatic rings of the phenols are saturated.
