PFA Coating

Home / Product Details

PFA Coating

PFA (Perfluoroalkoxy) Coating is a premium fluoropolymer coating that combines the exceptional chemical resistance of PTFE with the advantage of melt-processability similar to FEP. This allows PFA to form a dense, non-porous, pinhole-free coating with excellent adhesion and long-term durability.

PFA coatings are widely used on M.S. / S.S. tanks, pipes, fittings, valves, agitators, heat exchangers, baskets, screws, and critical process equipment operating in highly corrosive, high-purity, and high-temperature environments. Due to its superior film integrity and higher temperature capability, PFA is often preferred for severe chemical and pharmaceutical applications.

Key Features & Benefits

Outstanding Chemical Resistance
Resistant to almost all acids, alkalis, solvents, oxidizers, and aggressive chemicals, similar to PTFE.
Non-Porous & Pinhole-Free Coating
Melt-processable nature allows formation of a continuous, impermeable barrier against corrosion and permeation.
Higher Temperature Capability
Suitable for continuous service up to 260°C, making it superior to FEP and ETFE in high-temperature applications.
High Purity & Non-Contaminating
Ideal for pharmaceutical, API, semiconductor, and specialty chemical industries where contamination control is critical.
Smooth, Non-Stick Surface
Prevents fouling, scaling, and product build-up; easy to clean and maintain.
Low Coefficient of Friction
Reduces wear, galling, and torque in moving or contact components.
Excellent Adhesion & Film Integrity
Ensures long service life even under thermal cycling and aggressive chemical exposure.
Long Maintenance Cycles
Reduced recoating frequency lowers downtime and lifecycle costs.
