SF-301 is an off-white aqueous perfluoroalkoxy (PFA) dispersion stabilized with a non-ionic surfactant. It is a general-purpose dispersion that can be used to impart some of the unique properties of PFA to end products that would be difficult to make using traditional melt extrusion processes. This PFA dispersion can be used to coat or impregnate porous structures or to make thin films. It can be coated and melt bonded to polytetrafluoroethylene (PTFE) resin or used as a hot melt adhesive.
Heat-sealable top coatings for PTFE-coated fabrics for belting, circuit boards, architectural fabrics, and electrical insulation
Cast film for capacitor dielectrics or chemical barriers
Hot melt adhesive for PTFE, PFA, and FEP parts
Metal coatings
