HIREC 100

super hydrophobic coating with anti-fouling properties. Outdoor life is approximately 3 years!

HIREC 100
Super hydrophobic materials generally have the problem that water repellency deteriorates quickly when pollutants in the air adhere to the coating surface. To solve this problem, we developed HIREC100, which contains a photocatalytic material that keeps the coating surface fresh at all times. This makes it possible to expect the super water repellency to be maintained for approximately three years *. The coating of HIREC100 is white and opaque, but it can also be made colored.
*This is the expected period for our recommended film thickness (approximately 30μm). The period during which the super water repellency will be maintained varies depending on the usage environment, etc., so we do not guarantee the period during which the performance will be maintained.
