Abstract
There is disclosed a viscosity reduction method including: (a) forming an azeotropic mixture including water and a liquid capable of forming the azeotropic mixture with the water in a coating composition comprised of the water, a solvent, and a polymeric material selected from the group consisting of a fluorohydrocarbon polymer and a grafted elastomer composed of a polyorganosiloxane bonded to a fluoroelastomer; and (b) agitating the coating composition including the azeotropic mixture, thereby reducing the viscosity of the coating composition.
