Abstract: A method for using an ambient-temperature-drying aqueous elastomeric coating composition is provided. The coating composition comprises at least two mutually incompatible water-insoluble polymers, with at least one of the polymers comprising N-methylol functionality. The coating composition is used, for example, for high gloss elastomeric wall coatings or for sports surface coatings.

Abstract: Disclosed are aqueous acrylic thermosetting resinous compositions having an alkaline pH and containing a specific rheological modifier in critical amount, and application to metal sheets, curing the same, and in a preferred embodiment shaping the metals to achieve metal decoration. By "decorating" is meant applying synthetic resinous coatings to the metal followed by a mechanical forming operation such as the formation of can bodies or screw-threaded bottle caps. The compositon is thermosettable and comprises (A) a water-insoluble addition copolymer of certain monomers in latex form, (B) a water-soluble urea-formaldehyde or triazine-formaldehyde reaction product or a water-soluble methanol or ethanol ether thereof, or a combination of the aminoplast products, and, as an essential component, (C) a water-soluble polyethylene glycol having an average molecular weight of from about 400 to about 100,000.

Abstract: This invention discloses a polymer composition for the coating of substrates, comprising an aqueous alkaline blend having a binder consisting essentially of two components. Component A) is an addition copolymer of (1) about 3% to about 30% by weight of an olefinically unsaturated monomer containing a carboxyl group or mixture thereof, (2) at least one ester of acrylic or methacrylic acid, and, optionally, (3) other olefinically unsaturated monomers, the total of (1), (2) and (3) being 100%. The weight average molecular weight of the copolymer is between 10,000 and 500,000, and it is in the form of a solution or a colloidal solution in an aqueous phase. Component B) is an oligomeric addition copolymer of (1) at least one ester of acrylic or methacrylic acid, (2) 9% to about 50% of an olefinically unsaturated monomer having at least one carboxyl group, and, optionally, (3) other olefinically unsaturated monomers, the total of (1), (2) and (3) being 100%.

Abstract: Aqueous resinous compositions having an alkaline pH for application to metal sheets and curing the same prior to shaping the metals to achieve metal decoration are disclosed. By "decorating" is meant applying synthetic resinous coatings to the metal followed by a severe mechanical forming operation such as the formation of screw-threaded bottle caps. The composition is thermosettable and comprises (A) an addition copolymer of certain monomers and (B) a water-soluble urea-formaldehyde reaction product or a water-soluble methanor or ethanol ether thereof. The copolymer contains small amounts of carboxyl and amide and/or hydroxyl functionality. The weight ratio of (A) to (B) is from 35:65 to 65:35, and the solids content is between 40 and 80 percent.

Abstract: Low molecular weight copolymers (1) acrylic acid esters or methacrylic acid esters of alcohols such as methanol with (2) esters of bicyclic alcohols such as isobornyl alcohol and unsaturated acids such as methacrylic acid, as contrasted with high molecular weight copolymers of such monomers (1) and (2) (see U.S. Pat. No. 3,485,775) and as contrasted to other acrylic polymers, are found to be exceptional in compatibility with practically all types of polyesters and alkyds and with many other types of lacquer film-forming materials. The modifiers, particulary for alkyds, need not be selected on the basis of the oil length or solvent (aromatic or aliphatic), the modifiers being compatible with long oil alkyds, medium oil alkyds, and short oil alkyds. When small amounts of unsaturated amine-containing monomers or unsaturated carboxylic acids, or other polar monomers and combinations thereof, are incorporated in the polymer solutions, they become improved pigment dispersants.
