  • Patent number: 4332701
    Abstract: There are disclosed thermosettable polyester resins which are the reaction products of specified amounts of a benzenedicarboxylic acid component (e.g.: 1,3-benzenedicarboxylic acid), a trihydroxy alkyl component (e.g.: 2-ethyl-2-(hydroxymethyl)-1,3-propanediol), a short chain alkylene diol component having four or fewer carbon atoms in the primary carbon chain between the hydroxyl moieties (e.g.: 2,2-dimethyl-1,3-propanediol), a dihydroxy alkyl constituent having four to ten carbon atoms in the primary carbon chain between the hydroxyl moieties (e.g.: 1,6-hexanediol), and a monocarboxylic acid component (e.g.: benzoic acid). Such polyesters, having a number average molecular weight of from about 400 to about 1600 and a combined acid and hydroxyl number of about 50 to about 250 milligrams of KOH per gram of polyester, are found to be especially useful in high solids content coating formulations.

  • Patent number: 4229555
    Abstract: Linear thermosettable polyester resin compositions are prepared from benzenedicarboxylic acid, an alkyl dicarboxylic acid, (e.g. 1,6-hexanedioic acid), and a short chain alkylene diol component (e.g. 2,2-dimethyl-1,3-propanediol), the resin having a number average molecular weight of about 1,500 to about 5,000 and combined acid and hydroxyl values of about 20 to about 60 mg of KOH per gram of polyester. When these polyesters are combined with an aminoplast and an acid catalyst they form coating compositions which, when applied to a substrate and cured, provide a coating having an outstanding combination of hardness, adhesion, extendability, flexibility and dry heat resistance.

  • Patent number: 4212776
    Abstract: Water reducible self crosslinking epoxy ester-acrylate polymers are prepared by partially esterifying the epoxy groups of a polyepoxide with an ethylenically unsaturated fatty acid or a saturated fatty acid and copolymerizing the ester product with monoethylenically unsaturated monomers including methacrylic acid and an alkoxymethylacrylamide or alkoxymethylmethacrylamide, to afford a self crosslinking acid copolymer. This copolymer is solubilized in water with a volatile base, e.g., ammonia, trimethylamine, or dimethylethanolamine. Formulations based on these polymers are useful as metal coatings.

  • Patent number: 4140819
    Abstract: Linear polyester resins, terminated with carboxyl groups, and suitable for inclusion in heat-curable fluid coating compositions, are advantageously modified by capping a minor fraction of the carboxyl groups with a hydrocarbyl glycidyl ether. The capped resins produce water-reducible formulations that exhibit a fast curing rate and excellent adhesion when formulated with hexamethoxymethylmelamine, for example. Such fluid coating compositions may be used as industrial coatings and coil-coatings.
