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.
Electrostatic 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.
The number of coating layers applied depends on the required thickness.
