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.
- 9. Sixth Topcoat Layer (cured at high temperature)
- 8. Fifth Topcoat Layer (cured at high temperature)
- 7. Fourth Topcoat Layer (cured at high temperature)
- 6. Third Topcoat Layer (cured at high temperature)
- 5. Second Topcoat Layer (cured at high temperature)
- 4. First Topcoat Layer (cured at high temperature)
- 3. Primer Layer (base coat applied and oven cured)
- 2. Surface Preparation (sandblasting)
- 1. Steel Substrate
