Dyneon FC 2177 D Di-polymer of vinylidene fluoride and hexafluoropropylene 3M-Dyneon Fluoropolymers SEALANT Dyneon Fluoroelastomers have been designed to provide solutions to your unique application and processing needs. The proprietary cure system found in FE grades provides improved scorch safety over FC grades for faster curing, higher molding temperature processes. The FG grades have been FDA approved for use in food handling processes. And the FT (terpolymer) grades provide improved chemical resistance over dipolymers. Peroxide cured products are designated FLS. Dyneon™ Fluoroelastomer FC 2177D Medium viscosity, incorporated cure dipolymer formulated for bonded seal applications. Slower cure and excellent hot tear strength. di-polymer of vinyli-dene fluoride and hexafluoropropylene Medium viscosity Excellent hot tear strength for removing complex parts from mold (such as shaft seals) Medium viscosity, incorporated cure dipolymer of vinylidene fluoride and hexafluoropropylene. Used for bonded seal applications. Offers slow cure and very good hot tear strength.
