Fluoroplastic FEP Dispersion — Water-Based FEP Coating
Water-based dispersion of FEP (fluorinated ethylene propylene) resin — exceptional chemical and thermal resistance for coating metals, glass, ceramics and fabrics with corrosion-, heat- and stick-resistant protective layers.
What is Fluoroplastic FEP Dispersion?
Peflon FEP (fluorinated ethylene propylene) emulsions are water-based dispersions of FEP resin (CAS 25067-11-2) — a fluoropolymer known for exceptional chemical and thermal resistance. It is commonly used to coat metals, glass, ceramics and fabrics with a protective layer that resists corrosion, heat and adhesion.
Unlike PTFE dispersion, FEP is fully melt-fusible, so coatings flow into a smooth, pinhole-free, heat-sealable film at moderate temperatures — see general FEP property data.

Application of Fluoroplastic FEP Dispersion
FEP dispersion serves industrial, food, aerospace, semiconductor and medical markets — four primary use cases plus industry-specific coatings.
Heat-Sealable Top Coatings
For PTFE-coated fabrics — belting, circuit boards, architectural fabrics and electrical insulation.
Cast Film
Capacitor dielectrics and chemical barriers — thin-film casting with uniform thickness.
Hot-Melt Adhesive
Bonds PTFE, PFA and FEP parts — reliable fluoropolymer-to-fluoropolymer joining.
Metal Coatings
Protective coatings on steel, aluminum and specialty alloys — corrosion and wear resistance.
Electronic & Electrical Insulation
Excellent electrical insulation properties for demanding service.
Non-Stick Coating
Cookware, bakeware and metal coating film — release, chemical and heat resistance.
Fibers & Fabrics Treatment
Improves abrasion, water and corrosion resistance on technical textiles.
Medical Equipment
Coats medical devices — reduces bacterial adhesion and improves durability.
FEP Dispersion — Frequently Asked Questions
How is FEP dispersion different from PTFE dispersion?
Both are water-based fluoropolymer dispersions, but FEP is fully melt-fusible at moderate temperatures, so it forms a smooth, transparent, heat-sealable, pinhole-free film. PTFE dispersion needs high-temperature sintering and gives a more matte, porous film. FEP is chosen as a topcoat, sealing layer or where clarity and heat-sealability matter.
What is the solid content and how is FEP dispersion applied?
Typical solid content is around 55% with pH ~8.0 and viscosity ~250 mPa·s. It is applied by dip, spray, flow or cast coating, then dried to remove water and fused above the FEP melting point into a continuous film.
At what temperature does FEP dispersion fuse?
FEP melts near 260 °C, so coatings are typically dried then fused in the ~300–360 °C range to coalesce the particles into a clear, non-stick film — lower than the sintering temperature PTFE dispersion requires.
Which substrates can FEP dispersion coat?
Metals (steel, aluminum, specialty alloys), glass, ceramics and high-temperature fabrics — as protective, non-stick, corrosion- and heat-resistant coatings, and as a heat-sealable topcoat over PTFE-coated fabrics.
Is Peflon FEP dispersion PFOA-free and compliant?
Yes — it is PFOA-free and supports REACH and RoHS compliance, with OEM/ODM formulation and per-batch documentation available on request.
How is FEP dispersion packed and delivered?
Standard packing is 25 kg and 1250 kg containers, with typical delivery within 7 days. Store sealed, cool and above freezing, and gently re-homogenize before use.
