Methods for Producing Coating Powders, Catalysts and Drier Water-Borne Coatings by Spraying Compositions with Compressed Fluids

摘要: This invention relates to methods for spraying liquid compositions containing volatile solvent by using compressed fluids, such as carbon dioxide or ethane, form solid particulates, coating powders, and catalyst materials, which can be produced with narrow particle size distributions sprayed at higher solids levels, in ambient air heated applied just the spray instead of a chamber. Novel supports having beneficial morphology olefin catalysis. Drier water-borne coatings substrates fluids conventional water thereby reducing runs sags shortening dry times.
