3M™ Dyneon™ Fluoroelastomer FC 2178 is a high-viscosity copolymer of vinylidene fluoride and hexafluoropropylene with a 65.9% fluorine content. This fluoroelastomer (FKM) is curable with amine or bisphenol-type curing agents, and does not include an incorporated curative.

A Raw Gum
3M™ Dyneon™ Fluoroelastomer FC 2178 is a raw gum used for increasing viscosity and green strength. This FKM can be used in compression molding, and is amine or bisphenol curable.

Dyneon fluoroelastomer FC 2178 can be compounded using standard water-cooled internal mixers or two-roll mills with standard fillers and ingredients utilized in typical FKM formulations. The dry ingredients should be blended before adding to the masticated gum. For best results, Dyneon fluoroelastomer FC 2178 should be banded on the mill prior to adding the blended dry ingredients. Once mixed, the compounded stocks have good scorch resistance and storage stability.

Offering Different Quantities to Meet the Needs of the Job
Dyneon fluoroelastomer FC 2178 is packaged in slab form and is available in a returnable bulk shipping container system for 1,320 Ibs (600 kg) of material. The bulk container system is comprised of 48 individual polyethylene bags containing 27.5 Ibs (12.5 kg) of product. Smaller quantities are available in 55.1 Ib (25.0 kg) boxes.
