Abstract
In an aqueous curing composition of a fluoroelastomer comprising a fluoroelastomer, a curing agent and a surfactant, a surfactant with which an amount of decomposition residues is 0.3% by weight or less after being baked at 300° C. for 30 minutes, for example, a polyoxyethylene alkyl ether or a polyoxyethylenepolyoxypropylene block polymer, is used as a surfactant. Such a composition can make use of the inherent characteristics of the fluoroelastomer.
