Abstract: The invention relates to a coating composition comprising at least one binder and a multipurpose additive obtainable by reacting a vegetable oil with a diol or by transesterifying a vegetable oil lower alkyl ester with a diol, both reactions in the presence of a catalyst. The multipurpose additive is used to replace partly the solvent of the coating composition and/or to replace partly the binder thus reducing the VOC content and the viscosity.

Abstract: The present invention pertains to the uses of HiOmega flax (linseed) oil, a naturally occurring flax (linseed) with higher than normal alpha linolenic acid content in the production of stronger, more scratch and solvent resistant industrial products such as alkyd resins, epoxidized oils, epoxies, inks, coatings such as paints, enamels, varnishes and films and anti-spalling concrete preservatives.

Abstract: The quantity of dust generated by a sandable wall repair compound is reduced by adding a dust reducing additive to the compound. Dust reducing additives include oil, wax, and mixtures thereof. Dust reducing additives containing oil may include rheological and polar additives to minimize the bleeding of the oil into substrates to which the wall repair compound is applied.

Abstract: Mirror resin backings containing antioxidant pigments which are cyanamide derivatives of metals, are protective backing coatings for glass substrates and mirrors. The resin backings are melamine based resin coatings which provide anti-corrosion protection for the metal layers with metal cyanamide antioxidant pigments.

Abstract: A corrosion inhibitor pigment composition is based a solid solution of (Ni.sup.2+ +Co.sup.2+)-bis-hydrogen cyanamide.

Abstract: Soluble salt-free, contaminant-free antioxidant pigments which are cyanamide derivatives of metals, are provided in combination with organic resin polymers, as protective mirror backing coatings.

Abstract: Amine-complexed zinc salts of organic diacids selected from the group consisting of (i) dicarboxylic acids, (ii) diphenols, and (iii) phthalic acids. Specifically disclosed compounds include C.sub.2 -C.sub.3 alkylene diamine-complexed zinc salts of thiodiphenol and sulfonyldiphenol, and ethylene diamine-complexed salts of phthalic, isophthalic and terephthalic acids. Such amine-complexed zinc salts have utility as corrosion inhibitors in coating compositions for metallic substrates, e.g., paints based on alkyds, latexes or linseed oil. Also disclosed are anticorrosion additives, comprising the aforementioned amine-complexed salts distended on mineral fillers such as kaolin, and a method of making same by reaction of zinc oxide, amine, and organic diacid, at elevated temperatures, in an aqueous slurry of the mineral filler. At least the dicarboxylic acid and diphenol derived salts also display utility as inhibitors of marine growth (algae and barnacles) on substrates.

Abstract: An anticorrosion pigment suited for paints and lacquers and consisting of CaZn.sub.2 (PO.sub.4).sub.2 . 2H.sub.2 O crystallizing in the Scholzite lattice and having a specific surface according to BET of from 0.1 to 50 m.sup.2 /g is produced by a process wherein(a) (i) a salt solution containing calcium and zinc cations in a ratio of about 1:2 is normally, inversely or simultaneously precipitated in air at temperatures of up to about 100.degree. C. with an equivalent or substantially equivalent quantity of a solution containing an alkali metal or ammonium phosphate ion; or (ii) compounds of calcium and zinc, which can be decomposed with relatively strong acids or neutralized with acids, in a ratio of about 1:2, have phosphoric acid or ammonium phosphate added to them in approximately the quantity which is required for decomposition or neutralization, or in a slight excess of that quantity, at temperatures of up to about 100.degree. C.

Abstract: The zinc salts of 5-nitroisophthalic acid and of mononitroterephthalic acid inhibit the corrosion of steel when applied in otherwise conventional organic coatings.

Abstract: A diglycidyl ether of a diphenol, such as a diglycidyl ether of bisphenol A, is reacted with bisphenol S to form a chain-extended epoxy resin. This chain-extended epoxy resin is then esterified with a fatty acid derived from a drying oil, such as linseed oil fatty acid. The resulting epoxy resin ester is cut with a solvent for use as a rapid drying coating material. A primer using this material is also disclosed.
