Abstract: Latex paint in a container is inhibited against skinning by providing a thin layer of an aqueous mixture of diethylene glycol on the exposed surface of the latex paint after the container is filled with the paint.

Abstract: Curable epoxy-amine coatings comprised of pigmented mixtures of reactive amine-functional curing agents and epoxy resins are substantially improved by being rendered thixotropic or pseudoplastic by the inclusion of at least about 0.05% by weight of a thixotropic additive selected from monocarboxylic organic acid, dicarboxylic organic acid, tricarboxylic organic acid, fatty acid or polymerized fatty acid.

Abstract: Thermosetting powder coatings comprising reactive polymers containing reactive carboxyl, hydroxyl, and/or amide groups and adapted to be cross-linked with aminoplast resins are substantially improved by the inclusion of at least about 0.25% by weight of a heat curing catalyst. The catalyst is an amine salt of cyclohexyl sulfamic acid.

Abstract: A two component system is disclosed for forming rigid polyester reaction products in which each component is storable for an appreciable period of time but reacts upon contact with each other to form the rigid reaction product within a relatively short time. One component comprises a pre-catalyzed polyester resin which normally has a short pot life but which is extended by an excessive amount of an inhibitor. The second component is a synergistic accelerator combination consisting essentially of a metal soap and an aromatic tertiary amine. When the two components interreact, the accelerator combination overcomes the action of the excessive amount of the inhibitor and brings about a normal polymerization of the polyester resin. Optionally, the accelerator combination is part of a fibrous reinforcement and the aromatic amine is solid at room temperatures. This enables the second component to be more readily used in a dry, handleable form for easy storage.
