Product Description

FEP Dispersion / 50% Solid Content / Aqueous Liquid / No PFOA/PI Film Coating


Brief Introduction

Everflon® FEP Dispersion D50 is a off-white aqueous with non ionic surfactant. It provides inertness to nearly all industrial chemicals and solvents;stability at high temperatures;excellent dielectric properties; excellent weatherability and no-stick characteristics, using temperature is between -240°C (-400F) to 200°C (400F). It can be used to impart some the unique properties of FEP to end products that would be difficult to make using traditional melt extrusion processes.



Properties of Everflon FEP Dispersions

Everflon®  FEP Dispersion can be used to coat or impregnate porous structures, or to make thin lms. It can be coated and melt bonded to polytetrafluoroethylene (PTFE) resin or used as a hot melt adhesive.

Main Processing Way of Everflon FEP Dispersion D50


Conventional dip or flow techniques can be used for coating or impregnating high temperature fabrics, fibers,and other products with Everflon® FEP D50. A FEP resin coating on woven fabrics made of high-temperatureresistant fibers, can be made by dip coating. Successive passes may be necessary to build the desired thickness to produce a smooth, crack-free coating. Each coating layer is usually dried to remove water (typically at 120 °C [250 °F]), baked to remove the wetting agent (typically at 270 °C [518 °F]), and then heated above the crystalline melting point of the resin particles (approximately 265 °C [509 °F]). If the


Everflon® FEP D50 is being used as a top coat over a PTFE-coated fabric or other parts, the coating must be heated to melt the PTFE (approximately 337 °C [639 °F]) to maximize adhesion.

Other solid or liquid ingredients can be added to Everflon® FEP D50 to provide specific processing or finished product behavior

Everflon® FEP D50 must be properly stored to maximize the stability of the dispersion. The FEP particles will settle on prolonged standing and/or on prolonged heating— temperatures above 40 °C (104 °F) should be avoided.

The dispersion must be protected from freezing,which will cause irreversible settling.

The optimum storage temperature range is 7–24°C (45–75 °F). If dispersions are to be stored for extended periods, lower-temperature storage is desirable.

For optimal performance, Everflon® FEP D50 should be gently mixed or rolled monthly and prior to use.
Storage and handling areas should be clean.Keep dispersiondrums closed and clean to avoid both contamination and coagulation by drying at the liquid surface. High processing temperatures will cause even very small foreign particles to become visible and/or to make defects in finished products.


Good housekeeping and careful handling are essential.
