Abstract: A method of applying a coating composition, which preferably has a high solids content, to a workpiece. The method is one wherein a coating composition is atomized into liquid particles, an electrical charge is imparted with an induction charging electrode means on the particles substantially simultaneously with their formation, and the charged particles are directed to an electrically-receptive workpiece, and includes the improvement comprising heating the coating composition to adjust its conductivity and to enhance the induction charging of the particles formed from the heated coating composition. In a preferred embodiment, the charged particles are cooled before they reach the workpiece.

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 an hydroxyalkyl ester of an ethylenically-unsaturated carboxylic acid and a copolymerizable material; (B) an organic polyisocyanate; (C) a polymeric polyol of low glass transition 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: High solids, aqueous solvent-thinnable compositions are prepared by combining relatively low molecular weight, hydroxyl-containing organic materials with aminoplast resins. In general, the hydroxyl-containing materials are characterized by a room temperature water thinnability of 3 or more parts of water per 100 parts of organic material. The compositions can be used in a wide variety of different applications, and find particular utility in the formulation of unique coating compositions.

Abstract: Cured coatings having a high degree of extensibility and other desirable properties are obtained from compositions comprising a hydroxyl-containing, urethane reaction product containing a polyester component and an amine-aldehyde resin. Preferred compositions contain a polymeric polyol of low glass transition temperature. These compositions are storage-stable in one package, and the cured coatings are adherent, durable and highly extensible. These coatings are particularly useful on resilient and rubbery substrates, such as form rubber, polyurethane foam and vinyl foam, and on soft metal surfaces such as mild steel and aluminum.

Abstract: Thermosetting elastomeric coating compositions are disclosed. The resinous binder of the coating compositions is based on a hard polyester polyol containing cyclic moieties plasticized with a blend of soft polyurethane polyols, one of which has a high molecular weight and one of which has a low molecular weight, and cured with a curing agent capable of reacting with active hydrogens, for example, an aminoplast curing agent. The coating compositions are resistant to solvent popping and are particularly useful on elastomeric substrates such as high density polyurethane foams, as well as on metal substrates such as steel and aluminum.
