Clear and pigmented powder paint coatings are based on a thermosetting polymeric binder comprising low molecular weight, carboxylic acid functional, crystalline polyester and a coreactive glycidyl functional addition copolymer, preferably and glycidyl functional acrylic copolymer.

Thermosetting acid functional crystalline polyester modified acrylic

Thermosetting powder coating compositions are produced based on a low molecular weight glycidyl functional copolymer produced by solvent polymerization of ethylenic monomers in an organic solvent polymerization medium containing at least 15% by weight organic solvent based on the weight of solvent and monomers copolymerized, where the ethylenic monomers copolymerized comprise on a weight basis between about 15% and 35% glycidyl methacrylate, between about 5% and 60% methyl methacrylate, between about 2% and 15% butyl methacrylate, and between about 5% and 50% styrene, to produce glycidyl functional copolymer having a melt viscosity between 150 and 400 poise and a Tg between 80.degree. C. and 100.degree. C., where the copolymer is coreactive with carboxyl functional crosslinking compounds.

Thermosetting glycidyl modified acrylic powder coatings

An improved thermosetting coil coating composition contains a binder of a thermosetting polyester polymer particularly resistant to crystallization and adapted to be crosslinked with an aminoplast resin. The polyester comprises the condensation copolymer of 2-methyl-1,3-propane diol, neopentyl glycol, isophthalic acid, and terephthalic acid.

Thermosetting polyester coating

A high solids protective coating composition based on a coreactive thermosetting binder comprises low molecular weight hydroxyl functional acrylic copolymer, low molecular weight hydroxyl functional polyester polymer, hydroxy ester functional epoxy ester diluent, and a coreactive crosslinking amine material.

High solids coatings with reactive epoxy ester diluent

A high solids, thermosetting coating composition for painting substrates comprises low molecular weight acrylic polymer, low molecular weight polyester polymer, and low molecular weight urethane diluent, where the acrylic and polyester and urethane components each contain hydroxyl functionality and are coreactive with an amine derivative crosslinking resin to render the coating thermosetting.

High solids coatings with reactive diluent

Excellent adhesion of acrylic polymer coatings to plastic substrates can be obtained by the addition of an isocyanate modified polyester copolymer to the acrylic polymer coating.

High solids coatings for plastic substrates

Improved coating compositions which incorporate acrylate resins having multiple carbon-to-carbon bond unsaturation attached to the polymer chain through ester and/or urethane linkage are derived from the reaction product of:

Acrylate resin gel coat composition

An improved hydroxyl functional urethane-extended polyester is based on the condensation reaction of fumaric acid, one or more non-aromatic polyols, azelaic acid and optionally one or more non-aromatic carboxylic acids including lauric acid or stearic acid. The hydroxylated polyester urethane oligomer possesses a molecular weight below 2600 and a mole ratio of hydroxyl groups to urethane linkage of from 0.5 to 6. Gel coats prepared from these oligomers exhibit superior water resistance and improved weathering characteristics.
