Reactive liquids diluent and reactive dispersing agents for fluid concentrates, colorants and coating compositions, wherein the reactive liquid diluent and reactive dispersing agents have a viscosity less than 1,000 cps and contain at least one molecular species having at least three reactive unsaturated sites. The reactive liquid diluent or dispersing agent may be included a coating composition to form an interpenetrating polymer network in, or crosslink with, a pigmented coating composition containing a film-forming polymeric binder.

Pigment dispersion

Fluid concentrates, colorants and coating compositions contain solid pigment particles dispersed in a nonvolatilizing, reactive liquid diluent having a viscosity less than 1,000 cps and containing at least one molecular species having at least three reactive unsaturated sites. The reactive liquid diluent may serve as one or more of a dispersing medium for the solid pigment particles, a carrier, a coalescent and a humectant, and may crosslink or otherwise cure to form an interpenetrating polymer network in, or crosslink with, a pigmented coating composition containing a film-forming polymeric binder. Embodiments of the reactive liquid diluent can provide colorants and coating compositions having reduced levels of VOCs, conventional carriers, conventional dispersants, conventional coalescents and conventional humectants.

A silicone-modified polyester resin and methods for making the resin are described herein. The method includes production of a siliconized intermediate which is then esterified to give a silicone-modified polyester resin. Coating compositions including the silicone-modified polyester resin are provided, and coated articles with the coating composition applied to at least a portion of a surface thereof are also provided.

Silicone-modified polyester coating

The present description provides a water-reducible or water-dispersible coating system that can be used to form a durable, corrosion-resistant protective coating on a wide range of substrates. The coating system includes an alkyd resin prepared from a polyester feedstock that includes post-consumer recycled PET and a waste cooking oil feedstock. Methods for preparing the coating system and articles coated with the coating system are also described.

Water-reducible coating composition

Medium and high molecular weight polyester polymers are prepared in syrup form from an ester oligomer. The oligomer is converted to the polymer by polycondensation at elevated pressure and elevated temperature in a nonreactive carrier capable of forming an azeotrope with water. The ester oligomerization or polycondensation reactions desirably are monitored using a non-viscometric technique. The process has a rapid cycle time. The syrup contains the polymer and nonreactive carrier, and may more conveniently be used to make initially non-solid products such as polyester coatings than is the case when employing pelletized solid polyester resins.

Process for manufacturing medium and high molecular weight polyesters

The present invention provides a coating composition having excellent adhesion to metal substrates. The coating composition includes a binder comprising a polyester resin having an adhesion promoting group and an optional crosslinker. The present invention also provides articles having the coating composition applied to at least a portion of a surface thereof.

Polyester coating composition

An alkyd resin formed by reacting waste cooking oil, one or more aromatic polycarboxylic acids, aliphatic polycarboxylic acids, or esterified polymerization products, and one or more polyols.

Production of polymers from waste cooking oil

A primer/topcoat coil coating system employs crosslinkable branched hydroxyl-functional polyester-imide resins derived or derivable from a symmetric aromatic imide triol and a diacid or acid-producing derivative. The primer resin has a hydroxyl number greater than about 90 but not more than about 215, the topcoat resin has a hydroxyl number greater than about 100 but not more than about 215, and the primer and topcoat can each be hardened in 30 seconds or less to provide a coating having at least 0T flexibility with no tape off and at least 2H pencil hardness.

Crosslinkable imide polyester coating

Soak-in and strike through on the exposed end grain portions of low density or porous wood substrates including alder, birch, pine, poplar, and soft maple are reduced by applying to the end grain a solvent-borne coating composition containing an (i) alkyd resin having a hydroxyl number less than about 150, (ii) acid catalyst and (iii) cross linker. The resin desirably has a number average molecular weight greater than about 2000, and may have a Gardner coloration less than about 3 or may be a short oil alkyd based on coconut oil. By using a reduced hydroxyl number alkyd resin, a reduced cross linker amount may be employed, thereby reducing formaldehyde evolution in compositions made with methylated amino resin cross linkers such as methylated melamine resins.

Low penetration low formaldehyde alkyd composition

A high reflectivity coated substrate and coating composition employing a binder that includes a cycloaliphatic group and contains a polyester resin having a number average molecular weight from about 1,000 to 40,000. The binder contains less than 40 weight percent aromatic group containing compound and the weight ratio of pigment to binder is greater than 0.9:1. When the binder is blended with rutile TiOat a solids loading of 50 weight percent and coated to a dried film thickness of 0.00254 cm, the coating exhibits a Y-value of at least 85.5.

High-reflectivity polyester coating

A high reflectivity coated substrate and coating composition employing a binder containing a polyester resin that includes a cycloaliphatic group and has a number average molecular weight from about 1,000 to 40,000. The binder contains less than 40 weight percent aromatic group containing compound and the weight ratio of pigment to binder is greater than 0.9:1. When the binder is blended with rutile TiOat a solids loading of 50 weight percent and coated to a dried film thickness of 0.00254 cm, the coating exhibits a Y-value of at least 85.5.

The present invention provides a high reflectivity lighting fixture, comprising a coated reflector and a light source. The reflector is coated with a composition that includes a cycloaliphatic group containing polyester resin and a pigment. The present invention also provides coating compositions that may be used on other articles where high reflectivity is desired.
