Abstract: Preparation of a semi-crystalline catalyst for curing coating compositions wherein an isocyanate-sulfonate or -phosphonate is made by a Michael addition followed by chain extension with an isocyanate.

Abstract: Acrylic polymers with carboxylic acid and small amounts of phosphorus-containing strong acids are good pigment dispersants for use in water-based coating compositions.

Abstract: A method for preparing a stable aqueous dispersion of polyurethane modified polyacrylic involving chain extension of polyacrylic with isocyanate and hydroxyl- or amino-functional groups.

Abstract: An article of microwave cookware with a thermoset polyester substrate coated with an epoxy primer and a silicone resin topcoat which has two silicone resins with different methyl:phenyl ratios, one higher and the other lower to optimize both hardness and non-stick characteristics of the coating.

Abstract: An epoxyester linear block oligomer made with n-1 moles fatty acid units terminated with carboxylic acid groups and n moles of epoxy oligomer, when filled with carbon black, is a particularly effective electrically conductive primer for use over organic-based composites to be electrostatically painted.

Abstract: A low temperature curing coating composition containing 10-80% by weight of binder and 20-90% by weight of an organic solvent in which the binder is(1) a polymer of polymerized monomers selected from the following group: styrene, methyl methacrylate, an alkyl methacrylate, an alkyl acrylate, each having 2-12 carbon atoms in the alkyl group and the polymer having pendant amino ester groups or hydroxy aminoester groups;(2) an epoxy resin and(3) a polyamine curing agent,The composition is used as a primer or topcoating for metal substrates and curings at temperatures of 0.degree. C. to ambient temperatures and at high relative humidity and provides a primer that has excellent adhesion to the substrate and provided a durable, corrosion resistant finish.

Abstract: An epoxyester linear block oligomer made with n-1 moles fatty acid units terminated with carboxylic acid groups and n moles of epoxy oligomer is particularly suited for chip-resistant paints made with a low pigment volume concentration.

Abstract: Dispersion of an epoxy ester graft acrylic in water with a total of no more than 5% of organic volatiles and amines. These dispersions can be used in primer compositions for metal substrates having a minimum of organic solvent emissions and which can crosslink at temperatures from 110.degree.-200.degree. C., giving a good balance of hardness, flexibility, humidity, corrosion resistance and anti-chipping properties.

Abstract: Aluminum flake can be dispersed advantageously in a mixture of ethylene glycol and ethylene glycol monobutyl ether for use in solvent-based dispersions of poly(arylene sulfide) and optionally fluorocarbon.
