FEP Coating

Home / Product Details 

FEP Coating

FEP (Fluorinated Ethylene Propylene) Coating is a high-performance fluoropolymer coating that combines the excellent chemical resistance of PTFE with the advantage of melt-processability, allowing it to form smooth, non-porous, and pinhole-free coatings. FEP coatings provide outstanding protection against corrosion, chemical attack, sticking, and fouling, making them ideal for aggressive chemical and high-purity applications.

FEP coating is commonly applied on M.S. / S.S. pipes, fittings, valves, tanks, agitators, baskets, heat exchangers, fasteners, and process equipment used in chemical, pharmaceutical, food, and specialty industries. Compared to PTFE, FEP offers better film continuity and transparency, which helps in inspection and cleanliness-critical services.

Key Features & Benefits

  • Excellent Chemical Resistance
    Resistant to most acids, alkalis, solvents, and corrosive chemicals, similar to PTFE.

  • Smooth, Non-Porous & Non-Stick Surface
    Prevents material build-up, scaling, and contamination, ensuring easy cleaning.

  • Melt-Processable Fluoropolymer
    Allows uniform, pinhole-free coating with excellent film integrity.

  • Good Transparency
    Semi-transparent coating enables visual inspection of the substrate and cleanliness.

  • Wide Temperature Performance
    Suitable for continuous service up to 200°C.

  • Low Coefficient of Friction
    Reduces wear, galling, and torque in moving or contact components.

  • Strong Adhesion & Uniform Thickness
    Ensures long-lasting protection and consistent coating quality.

  • High Purity & Non-Contaminating
    Ideal for pharmaceutical, food, and specialty chemical processes and cleanliness-critical services.
