Abstract
An aqueous curing composition of a fluoroelastomer containing a fluoroelastomer, a fluororesin, a curing agent, which further contains a surfactant which leaves 0.3 wt. % or less of a decomposition residue after being heated at 300° C. for 30 minutes and/or a polar solvent having a boiling point of 300° C. or less and a surface tension of at least 30 dyne/cm at room temperature. When a coating film is formed from this aqueous composition, a large amount of the fluororesin contained therein can be bled up on the surface of the coating film. Thus, the durability and non-tackiness of the coating film can be improved.
