Water and Oil Repellent Coating –
PFAS-Free, Stay Ahead of Regulations!
Features

Point 01 Water and oil repellency
Achieves high water and oil repellency by maintaining large contact angles for both water and oil, ensuring these properties remain at an exceptionally high level.

Point 02 Exempt from PFAS* regulations
Does not contain fluorine, making it compliant with PFAS regulations. It also does not contain other environmentally harmful substances.

Point 03 Compatible with various substrates
Applicable to a variety of substrates, including not only glass but also metals and other materials.
Point 04 Low friction
Reduces the coefficient of friction, enabling use in environments where smooth sliding performance is required, even under harsh conditions.
*PFAS (Per- and Polyfluoroalkyl Substances): A general term for organic fluorine compounds, including perfluoroalkyl and polyfluoroalkyl substances, encompassing over 10000 types. Known for their excellent properties such as water, heat, and oil resistance, these compounds have been widely used in various products. However, concerns have arisen due to their long-term persistence in the environment, bioaccumulative nature, and potential impact on human health.
