	Additional Information
	Material Safety Data

Bisphenol AF is used to cross-link and cure fluoroelastomers, often along with an accelerator such as triphenyl benzyl phosphonium chloride. When used as a curing agent it produces elastomers with excellent chemical resistance and thermal stability. Bisphenol AF is also used as a monomer in the synthesis of specialty polymers. Polymers containing Bisphenol AF are useful in high temperature composites, in electronic materials and other specialty applications.
