Abstract
A low-gloss coating composition is disclosed. The coating composition comprises a unique blend of particles, including untreated silica and organic treated silica and wax treated silica. The use of these particles in combination provides for a significant reduction in the weight percent of certain particles that can impart a suitable level of gloss to a coating. The particles can be included, for example, in a urethane acrylate binder that can be cured using UV radiation.
