Built for harsh environments, our fluoropolymer coatings and linings provide chemical resistance, thermal stability, and anti-static properties. Backed by over 20 years of experience and 5,800+ projects completed, ChiNaite delivers trusted performance for demanding industrial needs.
Fluoropolymers Applied in Corrosion-Resistant Coating Process
Fluoropolymer coatings and linings rely on materials known for their chemical stability and resistance in harsh environments. Common options include PFA, PTFE (F4), ECTFE (F30, Halar), ETFE (F40), PVDF, and FEP (F46). These coating and lining materials perform reliably at high temperatures and in contact with aggressive chemicals, maintaining their structure without reacting with most solvents. Thanks to their low permeability, they create an effective barrier against corrosive substances, making them ideal for protective applications across various industries.
Our Advantages
ChiNaite has more than 20 years of experience in fluoropolymer coating and lining services, supported by ISO 9001 and ISO 14000 certifications. We are authorized to use high-purity fluoropolymers from leading brands including Chemours (DuPont), Solvay, and Daikin. Our coating operations are carried out in ISO Class 1,000 cleanrooms, where total metal impurities can be controlled to below 1 ppb.
For lining applications, we use materials from the same globally recognized suppliers, processed in ISO Class 10,000 cleanrooms, with total metal contaminants maintained under 10 ppt.

Examples
Fluoropolymer Coating for Semiconductor Manufacturing
Photoresist reaction vessel
High-purity PFA coatings are applied to ensure ultra-clean environments. Total metal contamination can be kept below 1PPb, with individual metals controlled under 0.2PPb. We also offer conductive PFA developed for semiconductor applications, with volume resistivity between 10⁻⁵ and 10⁻⁹ Ω•cm, and purity levels as low as 1PPb.
PI (Polyimide) reaction vessel
Designed for the synthesis of polyimide materials used in semiconductor-related processes. These vessels are coated with high-purity PFA to reduce metal ion contamination during chemical reactions. The coating meets strict purity requirements, keeping total metal content below 1 ppb and individual elements under 0.2 ppb.
Double-sided precision lapping machine
Applied in semiconductor substrate processing, transistor fabrication, and high-precision optics. PFA coatings are used on key components to improve corrosion resistance and maintain material purity. They effectively prevent metal contamination during polishing and withstand aggressive chemicals, including strong acids, bases, and solvents.
Wafer transfer robot
The coating prevents contamination from metal ions during wafer handling. It’s also suitable for coating ceramic parts and is available in anti-static versions when needed for ESD-sensitive applications.
Quartz lifting manipulator
Engineered to protect quartz and similar materials from aggressive media like hydrofluoric acid. The applied coating provides excellent hydrophobic and oleophobic properties, minimizing contamination from cleaning fluids. Suitable for working temperatures from -180 °C to 260 °C.
Examples of Fluoropolymer Coating and Lining Applications We offer on-site fluoropolymer processing services for equipment that's too large, complex, or sensitive to move, ensuring reliable protection without the hassle of transportation.
