The PFA Powder Coating provides a thick, durable, and chemically inert protective layer with excellent resistance to acids, alkalis, and solvents. It is widely applied in chemical reactors, valves, piping systems, and industrial equipment that require long-lasting corrosion protection and high purity.
Product Description
The PFA powder coating is a premium fluoropolymer coating designed to deliver exceptional chemical resistance, high purity, and thermal stability. Unlike liquid coatings, PFA powder coatings form a thick, uniform, and pinhole-free layer, ensuring long-term protection in aggressive chemical environments.
With excellent adhesion to metal substrates (with proper surface preparation and primer), it is widely used in chemical, semiconductor, pharmaceutical, and food processing industries where contamination-free operation is critical.
Key Features:
Thick and uniform protective coating
Chemically inert to almost all acids, bases, and solvents
High purity, suitable for cleanroom and pharmaceutical environments
Continuous service temperature up to 260°C
Excellent corrosion and abrasion resistance
Long-lasting performance in harsh industrial conditions
Typical Applications:
Chemical reactors & vessels – corrosion protection for aggressive chemicals
Valves & fittings – improved durability and chemical resistance
Clean piping systems – inert surface for ultrapure fluids
Pharmaceutical & food industries – hygienic and contamination-free surfaces
Industrial machinery – wear and corrosion protection

Q1: What is the advantage of PFA powder coating compared to liquid coatings?
A1: PFA powder coatings provide a thicker and more uniform layer, ensuring stronger protection, longer service life, and reduced risk of pinholes compared to liquid coatings.
Q2: What industries use PFA powder coatings the most?
A2: They are commonly used in chemical processing, semiconductor, food processing, and pharmaceutical industries, where high purity and chemical resistance are essential.
Q3: Can PFA powder coating be applied directly to metal?
A3: For optimal adhesion, it is recommended to use a primer layer (such as PFA Water-Based Primer) before applying the powder coating.
Q4: What is the maximum service temperature for PFA powder coatings?
A4: PFA powder coatings can withstand continuous service temperatures up to 260°C, with short-term peaks higher when properly sintered.
Q5: Are PFA powder coatings FDA compliant?
A5: Yes. PFA coatings can be used in food contact and pharmaceutical applications when processed according to FDA standards.
