Abstract
A process for preparing fuser belts in electrophotographic devices is disclosed. In this process the belt is coated, preferably using a vertical dip coating technique, with an aqueous solution containing a fluorocarbon polymer, such as Teflon, and a water-soluble polymer additive. Preferred additives include pectin, polyacrylic acid, and pectin/polyacrylic acid mixtures. This method provides efficient and effective vertical dip coating of the topcoat onto the fuser belt, particularly in terms of the uniformity of the coating, the stability of the coating dispersion, and the minimization of cracking when the coating is dried and sintered at high temperatures.
