VANAX® FC-20 Granules
Accelerator
Curing agent for fluoroelastomers. VANAX® FC-20 Granules contains a phosphonium based accelerator for use in bisphenol cure systems. Increasing the level will increase the cure rate with the compromise of scorch, lower properties, and possible mold fouling. A suggested ratio of VANAX FC-20 Granules: VANAX FC-30 Granules is 1:2 for fluoroelastomer copolymers and 3:4 for fluoroelastomer terpolymers.
