The present invention provides a water-based coating system that can be used to form a durable, abrasion resistant, tough, protective coating on a wide range of substrates. The coating system advantageously has excellent adhesion properties and can be directly coated onto stainless steel surfaces without requiring an intervening primer layer. Primer layers or other types of coatings can be used in combination with the coating system of the present invention if desired, however. The coating system is particularly effective for protecting metal-containing substrates such as intermodal, refrigerated cargo containers. The resultant coatings are flexible and impact resistant. Being water-based, the coating compositions have lower VOC emissions and less residual odor than solvent-based compositions.

Water-based coating system with improved adhesion to a wide range of coated and uncoated substrates including muffler grade stainless steel

Methodology for constructing composite particles from ingredients comprising two or more particulate components. The resultant particles are usefully incorporated into powder coating compositions. The approach also finds utility in other applications, including but not limited to the food, drug, and cosmetics industry. Fluidized particles are subjected to an intense, but relatively brief heating event. This causes associated particles to fusingly assemble into fused composite clusters.

Versatile processes for preparing and using novel composite particles in powder coating compositions

The invention relates to a process for coating powders on wood substrate comprising pre-treating at least one surface of the substrate with a substantially solvent free treating composition, applying a powder coating composition on the pre-treated surface of the substrate; and curing the powder coating composition. The treating composition includes at least one thermoset material and has a viscosity that is sufficiently low to allow the treating composition to wet out the surface(s) of the substrate and to penetrate into the surface fiber structure of the substrate.

Method of powder coating wood substrate

A method of manufacturing powder coating compositions, the powder coating compositions, and cured coatings made from the coating compositions are described. The method of preparing the coating compositions comprises combining a preformulated thermally softenable resin powder (having a defined T.sub.g) and a reflective pigments (such as a non-leafing or leafing metallic flake, mica, optically variable pigment, and the like) and then mixing the powder and flake under high shear conditions and assuring that the average temperature of the mixture remains below the T.sub.g of the resin during the high speed mixing process. The powder coating compositions are free of pasted aluminum flake and comprise thermally softenable resin particles having a number average diameter of between 15 and 60 microns, leafed metallic flakes having a number average maximum diameter of between 4 and 45 microns, said powder when coated onto a metallic surface in a thickness of at least 10 microns and melted and cured, providing a reflectivity of at least 400 at 20 degrees viewing angle. The resultant coating may also be free of the plasticizer, solvent or thickener used in pasted aluminum.
