Abstract
Powder coating compositions incorporate, by dry blending, a wax-coated silica additive in finely divided form. Further additives that may be incorporated by dry blending include aluminum oxide and/or aluminum hydroxide. The compositions offer advantages, for example, in terms of fluidity and in terms of first-time deposition of fine particles.
