High purity
Fluoropolymer coating secures environment purity of your process.
Known as high purity material, fluoropolymer is applied to the process for advance technology products/materials like electronics material, and semiconductor equipment. Our fluoropolymer coating is used for a variety application of these industries where to influence the quality by metal ion.
The amount of metal ion elution are depended on several factors such as "operating conditions", "fluoropolymer coating material", "coating application specification" and "coating application environment". Even it is said that "high purity material" (for elution prevention), the coating material and environment should be selected by the requirement from our customers.
As NIPPON FUSSO is a leading company of this application, we can offer the best fluoropolymer coating solution with a combination of "coating material selection", "coating layer structure", and "coating environment".

Common problems
- Metal elution from substrate of equipment, etc
- Elution from ordinary lining film
Fluoropolymer coating provides the solution
- Non contact with metal often used in semiconductor and pharmaceutical area, etc
- Maintenance of high purity
