Vulcanizable fluoroelastomer compositions providing vulcanizates having high adhesion to metals

摘要

Vulcanizable fluoroelastomer compositions based on vinylidene fluoride, comprising, as a vulcanizing system, a polyhydroxyl aromatic compound, a divalent metal compound of basic nature, and an accelerator consisting of a salt of ammonium or of phosphonium or of quaternary amino-phosphonium in which the anion is a complex of a Cd or Zn or Ni or Pb halide.
