International Classification:

B05D 102

US Classification:

427195, 427470, 427486, 427202, 4273881, 427410, 427421

Abstract:

Corrosion- and chip-resistant coatings for high tensile steel components, such as automotive coil springs, are formed from a coating powder composition of âtoughenedâ epoxy resin. In a single coat embodiment, the entire coating is loaded with at least 75 phr zinc powder. In a dual coat embodiment, an inner coat is loaded with at least 75 phr zinc and an outer, zinc-free coating is reinforced by the addition of fibers and/or by a foaming agent which renders it porous.

US Classification:

427558, 427195, 427201, 427375, 427393, 427485

Abstract:

Low gloss appearance in a coating derived from UV curable powder coatings can be achieved by using UV curable powder containing crystalline components or blends of crystalline and amorphous components and after heat fusing the powders together, allowing the crystalline components in the coating time to flow out and recrystallize to form a matte low gloss finish at a temperature of about the melting point of the crystalline component before curing with UV radiation.

Abstract:

A powder coating composition and method of applying it to a substrate, such as medium density fibreboard, consisting of a glycidyl methacrylate resin, a dicarboxylic acid cross-linking agent, a catalyst selected from phosphines, phosphonium, ammonium 2-phenyl-2-imidazoline, substituted imidazoline and isopropyl imidazole Bis-A epoxy resin adduct and a matte texturing agent. The inventive formulation is able to create a matte texture finish on the surface of the substrate. Since the cured final coating is resistant to yellowing and moisture, it is of great utility in the kitchen cabinet making industry.

Abstract:

The present invention provides UV curable coating powders comprising a blend of one or more than one free radical curable resin and one or more than one cationic curable resin, at least one free radical photoinitiator and at least one cationic photoinitiator, including suitable cross-linking agents and additives to enhance the chemical and physical properties of the coating appearance. The coating powder, preferably finely ground to between 5 and 30 microns in average particle size, is applied to a substrate, heat fused, and cured for an amount of time sufficient to form a powder coating having a low gloss finish.
