Fluoropolymer Coating & Lining

Fluoropolymer Coating & Lining

We focus on fluoropolymer coating and lining services that ensure high purity, chemical resistance, non-stick, easy cleaning, and anti-static performance. These solutions are tailored for demanding environments in industries such as semiconductors manufacturing, pharmaceuticals, petrochemicals, and food processing. Over the past two decades, the company has supported more than 5,800 clients by offering coating and lining processes based on advanced fluoropolymer materials. These technologies are designed to handle extreme temperatures (-190°C to 260°C) and vacuum applications, providing stable performance in harsh operating conditions. We offer a range of application methods tailored to different fluoropolymer materials, helping clients address challenges such as:

  • High procurement and maintenance costs of alloy systems
  • Enamel layer failure in glass-lined equipment
  • Incompatibility with strong acids, alkalis, fluorine, or iodine
  • Corrosion and wear in vacuum pumps

What Makes Us Unique

At ChiNaite, every detail in our coating process is designed to ensure quality, consistency, and compatibility with demanding applications.

  • Precision-Controlled Curing
    We use hot air circulation ovens imported from Japan to ensure uniform temperature control during curing. With a maximum capacity of 5 meters in diameter and 10 meters in length, our largest oven is one of the biggest used for fluoropolymer coating in China. To handle a variety of equipment sizes, we operate a total of 25 ovens in different specifications.
  • Certified Raw Materials
    All coating materials are imported and approved by Chemours (DuPont, USA), Daikin (Japan), and Solvay (USA), ensuring consistent performance and material traceability.
  • Dedicated Sandblasting Areas
    To prevent cross-contamination, stainless steel and carbon steel vessels are handled in separate sandblasting rooms, three for each material type, enabling strict quality control at every stage.
  • Electr ostatic Powder Coating Range
    We offer five fluoropolymer options for electrostatic powder coating: PTFE (F4), PFA, FEP (F46), ETFE (F40), ECTFE (Halar, F30), and PVDF.
  • Fluoropolymer Emulsion Coating Options
    Our emulsion-based coating services include PTFE, PFA, and FEP (F46) to meet different performance and process requirements.
