Super hydrophobic material with antifouling properties. Lifespan outdoors is about 3 years!

Contact us
Super hydrophobic materials generally have the problem that their Super hydrophobic performance quickly deteriorates when atmospheric pollutants adhere to the coating surface. To solve this problem, we developed HIREC100, which can keep the paint surface always fresh by incorporating photocatalyst materials. As a result, it is now possible to expect Super hydrophobic performance to be maintained for approximately 3 years *. The coating film of HIREC100 is white and opaque, but it can be colored.
*This is the expected period based on our recommended film thickness (approximately 30μm). The maintenance period of Super hydrophobic performance varies depending on the usage environment, so we cannot guarantee the performance maintenance period.
