Our fluoropolymer coating agent is a solution in which fluorinated compounds are uniformly dispersed in a solvent, allowing various performances to be imparted to the surface of the substrate through wet processes such as dipping and brush application. We offer a range of products that leverage the properties of fluorine, including environmentally friendly fast-drying solvents and water-based options. **Main Characteristics of Fast-Drying Fluorine Coatings** ◎ Water Repellency (Hydrophobicity), Moisture Resistance, Waterproofing In addition to excellent water repellency and moisture resistance, it is possible to achieve a low sliding angle and a high receding contact angle. Even with a slight incline, water droplets flow off, making it usable as a hydrophobic coating agent. ◎ Moisture-Proof Insulation and Acid Resistance In addition to moisture-proof insulation, it also exhibits high effectiveness in acid resistance. ◎ Oil Repellency (Oil Barrier, Prevention of Lubricating Oil Diffusion and Oozing) With high oil repellency, it prevents the diffusion and oozing of lubricating oils and greases. ◎ Release Properties It can be used on molds and other surfaces as a means to prevent resin adhesion to unintended areas. ◎ Stain Resistance It exhibits stain resistance by repelling water and oil stains, which are common causes of dirt. ◎ Low Friction It has the property of imparting "low friction" by lowering the coefficient of friction on the surface of the substrate.

PFOS stands for perfluorooctanesulfonic acid, and PFOA stands for perfluorooctanoic acid. Both PFOS and PFOA are persistent organic fluorinated compounds that are hardly biodegradable and remain in the environment for a long time. They possess unique properties such as water repellency, oil repellency, chemical resistance, and stability, and are widely used in applications such as water and oil repellents, surface treatment agents, surfactants, anti-reflective agents for semiconductors, metal plating agents, anti-fouling agents, cleaning agents, release agents, emulsifiers, fire extinguishing agents, and coating agents. The persistent organic fluorinated compound PFOS is regulated under the Stockholm Convention on Persistent Organic Pollutants (POPs), and in Japan, it is designated as a Type 1 specified chemical substance under the Chemical Substances Control Law. Additionally, PFOA is designated as a Type 1 monitored chemical substance under the same law and is subject to REACH regulations along with other organic fluorinated compounds. The list of restricted substances under the REACH regulation has been amended, and PFOA and its salts are now subject to regulation, requiring exports to the EU to demonstrate compliance with these regulations. Our company, "DuraSurf," offers fluorinated products that comply with PFOA regulations.
