Description

UV curable powder coating is an attractive technology which has far less environmental impact. Than conventional coating processes. Since powder systems are solvent-free they reduce air pollutants and reduce waste streams by eliminating the disposable of leftover wet paint. For these reasons the Air Force is interested in expanding it use of UV curable powder coatings. However, these UV cured coatings generally have a medium to high gloss finish, while military and weapon system require a flat matte finish. TDA has recently developed a new nanomaterial flattening additive which increases surface roughness. In this Phase I project TDA will demonstrate this additive can be used to reduce gloss in a powder coating formulation that provides good durability and adhesion. BENEFIT: Flattening agents could also be employed in a wide variety of other military coating applications. Beyond aerospace coatings this technology could also be applied to make CARC UV curable powder coatings. Additionally, commercial users may be interested in matte textures for furniture and other decorative materials.
