Coating compositions

The overall performance of water-reducible polymer dispersions, more specifically alkyd dispersions, can be substantially improved by utilizing resins derived from acidolysis reaction products of polyalkylene terephthalates and polyalkylene naphthalates. According to this invention, polymer dispersions can be produced from low acid value polymers and yet have good water dispersibility. When an aqueous coating composition is formulated using the dispersion of this invention, a final coating is formed that has good hydrolytic stability, and when blended with a latex, exhibits improved gloss and wet adhesion.

Aqueous polymer dispersions

This invention relates to high solids, low VOC, low viscosity, filterable, non-gritty non-aqueous dispersions, and coating compositions containing said non-aqueous dispersions.

Non-aqueous dispersions

Novel thixotropic alkyd resins are obtained by reacting at a temperature of between about 120.degree. C. to about 150.degree. C. for at least one hour (a) at least one alkyd resin and (b) a polyamide comprising the reaction product of: (i) a polycarboxylic acid; (ii) an active hydrogen compound having the formula X.sub.m --R--Y.sub.n, wherein R represents a group containing from 2 to 12 carbon atoms, X and Y are independently selected from primary amino, secondary amino and hydroxy, and m and n are each at least 1 and the sum of (m+n) is at least 2; and (iii) a capping agent comprised of an unsaturated and/or hydroxy functional monocarboxylic acid having from 8 to 22 carbon atom. The thixotropic alkyd resins of the present invention are particularly useful in preparing thixotropic paint and coating compositions having superior leveling and sag resistance.

Thixotropic alkyd resins and the use thereof in coating compositions

Coating compositions derived from the acidolysis of polyethylene terephthalate.

Aqueous coating compositions from polyethylene terephthalate

This invention relates to aerosol paint and coating compositions comprising non-aqueous dispersions.

Aerosol compositions containing non-aqueous dispersions

This Invention relates to aerosol paint and coating compositions comprising non-aqueous dispersions.

Coating compositions derived from the alcoholysis of polyethylene terephthalate.

This invention relates to fatty acid modified alkyd resins and the use thereof in formulation of high solids interior and exterior paints capable of curing at ambient temperatures without the use of appreciable amounts of solvent. More specifically, the invention relates to high solids alkyd coatings derived from fatty acid oil modified alkyd resins having low viscosities capable of forming finishes that have good physical characteristics such as high gloss, resistance to humidity, excellent adhesion and a good hardness. These oil modified alkyd resins have number average molecular weights of less than about 6,000 and are derived from the polymerization of drying oil fatty acids, dibasic aromatic acids, polyols, at least one unsaturated monocarboxylic acid and an unsaturated monohydric alcohol.

Alkyd resins and the use thereof for high solids coatings

This invention relates to high solids alkyds, non-aqueous dispersions, and coating compositions containing those alkyds and non-aqueous dispersions, having non-volatile materials contents greater than about 75% NVM, with very low volatile organic contents of less than 305 g/l, which exhibit excellent stability, viscosity and tack-free and dry times when formulated as air dry coating compositions.
