Abstract
There is provided a polyol-crosslinkable fluorine-containing elastomer composition which is excellent in chemical resistance, solvent resistance (especially resistance to an acidic solvent) and fuel resistance (especially biofuel resistance) and is crosslinkable at the same crosslinking speed as in the case of using calcium hydroxide in a usual amount even without blending calcium hydroxide (or decreasing a blending amount of calcium hydroxide). The fluorine-containing elastomer composition comprises a polyol-crosslinkable fluorine-containing elastomer, a polyol crosslinking agent and a silicate of an alkali metal.
