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.
