Viton™ VC-3
Viton™ VC-3 is a blocked diamine cross-linking agent used to cure A, B, and E types of Viton™ fluoroelastomers.
Chemours Viton™ VC-3, previously known as Diak-3, is a blocked diamine cross-linker used to improve the processing safety of A, B, and E types of fluoroelastomers. Viton™ VC-3 has a plasticizing effect on vulcanizates. The typical usage level for Viton™ VC-1 is 1 to 1.5 phr.
The main difference between the Viton™ VC process agents in processing safety. Products cured with Viton™ VC-3 provide excellent processing safety and exhibit some plasticizing effect, while Viton™ VC-1 offers the best compression set and physical properties. In addition, cures for Viton™ A, B, and E types of fluoroelastomers are produced with roughly 3 phr of Viton™ VC-3.
