Product Description

PFA Dispersion / 50% Solid Content / Aqueous Liquid / No PFOA


Brief Introduction

Everflon® PFA Dispersion D450 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 dicult 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.

Main Processing Way of Everflon PFA Dispersion D450


Conventional coating techniques, such as dip, spray, spin, or roller coating, can be used for coating or impregnating high temperature materials with Everflon® PFA D450. Thin coats, usually less than 5 um (0.2 mil), are applied to prevent mud cracking as the coating dries. The water is normally removed at 120 °C [250 °F], followed by heating to remove the wetting agent (typically at 250–270 °C [482–518 °F]).


Final consolidation is done above the 305 °C (581 °F) melt point. If the Everflon® PFA D450 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.

Prolonged heating above 370 °C (698 °F) should be avoided, as this could lead to thermal degradation of the Everflon® PFA D450 polymer.

Other solid or liquid ingredients can be added to Everflon® PFA D450 to provide specific processing or finished product behavior.

Everflon® PFA D450 must be properly stored to maximize the stability of the dispersion. The PFA 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® PFA 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.
