FLUORORUBBER COATING COMPOSITION

摘要

A vulcanizable fluororubber composition which comprises a fluorinated elastomeric copolymer comprising repeating units of -CH2- in the backbone chain, a polyol-base vulcanizing agent, and a vulcanization accelerator comprising a salt or complex of a basic compound having a pKa value of 8 or above with an organic acid. This composition is a one-pack vulcanizable composition having a long pot life and can give a vulcanized coating film at a relatively low temperature in a short time. Further, the composition can be applied by dispenser coating or screen process printing even when the concentration of the fluorinated elastomeric copolymer in the composition is high.
