FLUORORUBBER COATING COMPOSITION AND METHOD FOR MODIFYING BASE SURFACE

摘要

A fluororubber coating composition which comprises (a) a fluororubber having -CH2- groups in the main chain, (b) a fluoropolyether oil having a functional group capable of chemically bonding to the fluororubber (a) upon heating, (c) a vulcanizing agent and, if necessary, a vulcanizing assistant, and (d) a medium. When the composition is applied to a base and fired, a persistent tack-free property can be imparted to the base surface without impairing the characteristics of the fluororubber, such as elasticity, and heat and chemical resistance.
