Abstract
Methods for powder coating that include applying a powder coating composition to a substrate via an electrostatic gun. The powder coating composition includes a mixture of two or more materials having different densities, such as a mixture of aerogel particles and fluoropolymer-containing particles. The electrostatic gun can have a high-voltage generator that generates a negative polarity voltage between about 0 KV and about 100 KV during application of the powder coating composition, and the electrostatic gun can have a round spray nozzle. Methods of making fuser members using such powder coating methods, fuser members prepared by such methods, and methods of preparing low gloss images using such fuser members.
