Viton IBR-401C fluoroelastomer Dupont Dow Elastomers Fluoropolymers SEALANT ADHESIVE In adhesives applications, Viton forms a strong bond that can flex without failure after repeated temperature cycling and vibration. Terpolymer of fluoroethylene, vinylidene fluoride, and propylene, plus cure chemicals. Viton IBR-401C is a nominal 40 Mooney viscosity, bisphenol curative-containing precompound, designed and formulated for optimized performance in applications which demand resistance to the very aggressive additive packages typical of those used in today’s automotive lubricating oils. Vulcanizates based on Viton IBR-401C exhibit resistance to amines, and amine-based additives that is improved relative to conventional fluoroelastomers, and provide excellent service ability in aggressive motor oils, transmission fluids, and coolants that contain high levels of aggressive corrosion inhibitors. Viton IBR-401C features: Incorporated bisphenol cure system Improved resistance to amine-based oil and coolant additives Viscosity, rheology, and cure/scorch characteristics suitable for compression molding Excellent mold release Good hot tear resistance, good demolding performance in molds with undercuts Very good compression set resistance Compression molding of bonded, dynamic seals, such as shaft seals, valve stem seals, etc. Compression molded O-rings and gaskets Bisphenol curative terpolymer of fluoroethylene, vinylidene fluoride, and propylene.
