  • Mineral-filled coatings having enhanced abrasion resistance and wear clarity and methods for using the same
    Patent number: 6833186
    Abstract: An abrasion resistant coating composition having excellent wear clarity is disclosed. The coating composition comprises a unique blend of particles, including alumina that has been treated with an organosilane and silica that is either similarly treated or left untreated. The use of these particles in combination allows for a significant reduction in the weight percent of wear resistant particles that can impart a suitable level of abrasion resistance to a coating. The particles can be included, for example, in a urethane acrylate binder that can be cured using UV radiation. Methods for using these coatings are also disclosed.
