Abstract: Coating compositions are formulated using a polyol with a hydroxyl functionality of at least three modified by reaction with a glycidyl ether in proportion of about 0.1 to about 4, preferably from about 0.2 to about 2 moles of glycidyl ether per mole of polyol, with which is combined, as curing agent, a compatible aminoplast resin. When the polyol is trimethylol ethane, for example, and is so modified with allyl or butyl glycidyl ether, for example, and is so modified with allyl or butyl glycidyl ether, for example, and the compositions contain a methylated melamine formaldehyde condensate as curing agent, they are especially suitable for clear top coating surfaces of wood or flat woodstock containing printing inks to simulate woodgrain, to provide a durable coating highly adherent to the inks as well as the cellulosic materials. The compositions may contain high solids content yet they are stable on storage without development of crystallization and are reducible or thinnable with water.

Abstract: Quaternary ammonium hydroxide-containing polymers and their use in coating applications are disclosed. The quaternary ammonium hydroxide-containing polymers are prepared from reacting a polyglycidyl ether of a cyclic polyol with a tertiary amine in the presence of a sufficient amount of water for the formation of quaternary hydroxide groups.The quaternary ammonium hydroxide-containing polymers are particularly good as electrocoating resins in that they electrodeposit without generating acid counterion. They are also good in other conventional coating applications such as dip, flow, spray and roll coating in that the resulting coating can be baked without the generation of corrosive acid.

Abstract: Cured coatings having a high degree of extensibility, gloss retention, good sprayability and other desirable properties are obtained from compositions comprising (A) an interpolymer of a hydroxyalkyl ester of an ethylenically-unsaturated carboxylic acid and a copolymerizable material; (B) an organic polyisocyanate; (C) a polymeric polyol of low glass transistion temperature; and (D) a curing agent, present either externally and/or as a part of the interpolymer. These compositions, when used as coatings, are durable, adherent and highly extensible. The coatings are particularly useful on resilient and rubbery substrates such as EPDM rubber, foam rubber, polyurethane foam and vinyl foam and on soft metal surfaces such as steel and aluminum.

Abstract: Thermosetting resins containing hydroxyl groups which can be cured with aminoplast resins are stabilized by the addition of 1,4-diazo[2,2,2]-bicyclooctane. This method is particularly useful in stabilizing the gloss retention of extensible coatings formed by curing a hydroxyl-containing urethane product with an aminoplast resin. Such coatings can be applied to virtually any solid substrate and are especially useful on rubbery, resilient substrates such as polyurethane or polyethylene foam, natural or synthetic rubber or rubber foam, and various elastomeric plastic materials. They are also particularly useful on other substrates such as mild steel or aluminum.

Abstract: A water-diluted, ungelled, non-sedimenting polyurethane and a process for preparing such a polyurethane in an aqueous medium is disclosed. High molecular weight thermoplastic products are obtained by chain extending in aqueous medium an NCO polymer having a salt group equivalent weight of 6000 or less and substantially free of reactive hydrogen. The average functionality and equivalent ratio of the polyisocyanate and active hydrogen-containing materials used in making the NCO polymer, as well as the functionality of the chain extender, are carefully controlled so as to get high molecular weight ungelled products. Thermosetting compositions can be made by adding curing agent to the chain extended material. Curing agents can also be incorporated into the polymer molecule either in the making of the partially reacted NCO-containing prepolymer or by further reaction with the partially reacted NCO-containing prepolymer. The water-dispersed polyurethanes of the present invention are excellent film formers, capable of making coatings with a wide spectrum of desirable properties. In addition, they can be added to other water-compatible compositions to improve flexibility, hardness, drying and other coating properties.
