Teflflon™  PFAD 335D 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. It 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. 

The PFA resin in Teflflon™  PFAD 335D is a melt flowable  thermoplastic, providing superior properties typical of  fluoroplastic resins: retention of properties after service at  260 °C (500 °F) and useful properties at –240 °C (–400 °F). 

Teflflon™  PFAD 335D aqueous dispersion provides: 

• Inertness to nearly all industrial chemicals and solvents  

• Stability at high temperatures

• Excellent dielectric properties 

• Excellent weatherability 

• Excellent anti-stick properties 

Typical Applications  

• 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
