Embodiments of the present disclosure include processes for autodepositing a coating on a metal surface, a method of producing a coating on a non-stainless steel metal substrate surface, and an alkaline coating composition, where the process for autodepositing a coating on a metal substrate surface includes immersing at least a portion of the metal substrate surface in a coating composition that includes a latex and an amount of base sufficient to raise the pH of the composition to an alkaline pH, where the coating autodeposits on the metal substrate surface, as metal ions from the metal substrate surface interact with the alkaline coating composition.

Alkaline coating composition for autodeposition

Fast hardening aqueous latexes and coating compositions, including paints such as traffic paints, comprising a triazole exhibit less plate out onto process metal surfaces compared to similar triazole-free compositions.

Aqueous coating composition having reduced plate out

A method of reducing plate out onto metal surfaces of aqueous latexes and coating compositions, including paints such as traffic paints, the method comprising employing a composition comprising a triazole. The method produces less plate out onto process metal surfaces compared to coatings prepared from similar triazole-free compositions.

Method for reducing plate out of aqueous coating compositions

This invention relates to polymers, especially emulsion polymers, and their use for the thickening of a variety of aqueous systems, to methods of thickening utilizing the polymers, to enhancement of such thickening by the addition of surfactants, solvents or non-solvents, and to other aspects including coating compositions and other aqueous systems thickened with the polymers. This invention also relates to new complex hydrophobe-containing oligomers and their use in producing the polymers of this invention.

Complex hydrophobe-containing oligomers

This invention relates to complex hydrophobe compounds and to alkoxylation products, i.e., condensation reaction products of alkylene oxides and complex hydrophobe compounds having at least one active hydrogen. This invention also relates to alkoxylation products that have beneficial, narrow molecular weight ranges.

Complex hydrophobe compounds

An aqueous emulsion copolymer of monoethylenically unsaturated monomers which includes from about 0.1 weight % or less to about 10 weight % or greater of a monoethylenically unsaturated macromonomer. These monomers can improve the brush drag of paints made with the emulsion copolymers, and in some instances the leveling is simultaneously improved.

Aqueous latexes containing macromonomers

This invention relates to a method of coating a substrate by applying thereon an aqueous coating composition containing an alkali-swellable complex hydrophobe associative thickener. When a blade coater is utilized to apply said composition, lower blade pressures are obtained allowing increased line speeds to be used without scratching the substrate.

Polymers containing macromonomers and their use in a method of coating

Polysaccharides, including hydroxyethyl cellulose, having complex hydrophobic group substitution, provide latex compositions, such as paints, with improved rheology and stability. Improved processes for producing such polysaccharides are also provided.

Polysaccharides containing complex hydrophobic groups

Polymers containing macromonomers

Water-soluble polymers are disclosed which comprise hydrophobic segments, each segment containing at least one hydrophobic group or comlex hydrophobic group covalently bonded to the polymer, wherein the polymer has an amount of complex hydrophobic groups sufficient to provide for enhanced thickening of aqueous solutions containing the polymer. These polymers provide superior thickening and leveling in aqueous systems through hydrophobic associations, and aid suspension of particulate materials in non-aqueous systems.

Polymers containing complex hydrophobic groups

A method of coating a substrate with an aqueous coating composition that includes an alkali-swellable associative thickener is disclosed. The associative thickener is produced from a monoethylenically unsaturated carboxylic acid, a monoethylenically unsaturated monomer lacking surfactant capacity, a non-ionic urethane monomer, and, optionally, a polyethylenically unsaturated monomer.
