Notice of Renewal of Super Water Repellent Material HIREC
Notice of Renewal of Super Water Repellent Material HIREC
super hydrophobic coating has completely changed the conventional concept of Super hydrophobic materials
Initial contact angle exceeds 150°
Extremely water repellency
The photo shows water droplets dripped onto a HIREC painted surface.Due to the super water repellency of the coating surface, water droplets become almost spherical, so a water film is hardly formed.
Maintains long-term water repellency
Self-cleaning function
The self-cleaning function using photocatalyst ensures that a clean coating surface is always exposed.
This ensures that water repellency remains for a long period of time.
This ensures that water repellency remains for a long period of time.
*HIREC450 and HIREC1450NF are primarily for indoor use and do not have a self-cleaning function.

Also effective in reducing snow and ice buildup
The photo shows an example of snow accumulation reduction using HIREC coating. On the left side, a large amount of snow has accumulated on the uncoated HIREC surface, but on the right side, the HIREC coated surface, the snow falls off before it can pile up too high.
Features of HIREC
Overwhelming water repellency
On a HIREC coated surface, water droplets maintain an almost spherical shape, demonstrating super water repellency to the point that they cannot remain in place.
Contact angle of typical fluorine-treated products: Approximately 100°
HIREC initial contact angle: 150° or more
Self-cleaning function using photocatalyst
HIREC-R, HIREC1100, and HIREC300-W have a self-cleaning function due to the photocatalytic effect.
Dust and dirt present in the air will adhere to Super hydrophobic and generally cause water repellency to gradually decrease. In addition, the ultraviolet rays contained in sunlight will cause the coating surface to deteriorate, which will also cause water repellency to decrease.
On the other hand, the HIREC series contains photocatalytic materials that, even if dirt adheres to the surface, exhibit a self-cleaning function when exposed to sunlight, revealing a new, water repellency repellent surface.
Thanks to this function, it is expected that the super water repellency water repellency paint *.

Also effective in preventing snow accumulation
By applying HIREC in advance, you can prevent snow, ice, and icicles from accumulating, reducing damage caused by falling snow and ice.Click here for customer application examples
