Lithium-ion battery manufacturing relies on equipment that must withstand strong chemical exposure and high-purity requirements. Fluoropolymer coatings and linings help maintain process reliability by minimizing corrosion, contamination, and material degradation. Thanks to our more than 20 years of experience, we have a team capable of delivering tailored solutions for reactors, storage tanks, and mobile containers used in battery production. Our facility includes 27 curing ovens, one of which measures 5 meters in diameter and 10 meters in length, the largest of its kind in China, along with 15 ovens at 4.5 meters and four small electric models for pilot applications. We also operate a 1000-class cleanroom for precision coating, a 4000㎡ 10,000-class cleanroom for lining, and a 5000㎡ industrial-grade lining workshop. On-site application services are available for large or difficult-to-transport equipment.

• Corrosion resistance
• Anti-stick surface
• Electrostatic dissipation
• Low friction

• Mixing
• Filtration
• Drying
• Mobile containers
• Storage tanks
• Semiconductor cleaning components
• Columns
• Adsorption resin colum

Equipment used in lithium battery production often requires chemical resistance and high-purity surface protection. To meet these needs, we apply PFA, PTFE (F4), ECTFE (F30, Halar), ETFE (F40), PVDF, and FEP (F46) coatings and linings across a wide range of equipment, including reactors, large storage tanks, mobile containers, and filtration units. When equipment size makes transport difficult, on-site application is available without limitations.
