Overview
Chemours Viton™ VC-20 is an accelerator and curing agent based on 33% benzyl-triphenyl-phosphonium chloride (BTPPC) and 67% Viton™ fluoroelastomer polymer. Viton™ VC-20 controls the rate of curing A, B, and F types of Viton™ FKM fluoroelastomer rubber. Viton™ VC-20 contains a phosphonium-based accelerator and BpAF cross-linking agent that controls the cure rate. Viton™ VC-20 cross-linking agent improves production processes and enhances finished fluoroelastomer rubber polymers.
Viton™ VC-20 is used along with Viton™ VC-30 adjust the cure state and cure rate. Viton™ VC-20 cannot be used with PMVE-containing fluoroelastomer rubber. Viton™ VC-20 can further accelerate the cure rate of the curative containing precompounds while being used with Viton™ VC-50 in gum compounds to impart faster cure speeds.
