Chemours Teflon™ 857G-519 One coat PTFE Coating System
Categories: Polymer; Thermoplastic; Fluoropolymer; Polytetrafluoroethylene (PTFE)

Material Notes: One coat systems can be applied to smooth, clean metal and used with food processing equipment, fasteners, and components in the automotive and aerospace markets. These coatings are formulated with special blends of fluoropolymers and other high-performance resins. This formulation gives them the ability to form layers—or stratify—in the cure process, which makes the fluoropolymer more concentrated at the surface. This stratification allows the one coat to better retain its hardness, corrosion and abrasion resistance, low friction, and nonstick properties during baking.
