NTT Advanced Technology's Super hydrophobic Super hydrophobic HIREC ® has completely redefined the concept of water-repellent materials.

Surfaces coated with the Super hydrophobic material HIREC repel water and do not get wet, in other words, almost no water film forms.

[Have you taken measures against snow and icicles?] ]

It is important to take measures to prevent the accretion of snow and ice, and to reduce the damage caused by falling snow and ice before damage occurs.

If you are in trouble with snow, ice, or icicles on your equipment, we recommend installing HIREC!

HIREC, a Super hydrophobic material, is widely used not only to catch water but also to prevent snow from landing.

Features of HIREC Overwhelming Super hydrophobic

Typical Super hydrophobic materials such as Teflon have a contact angle of about 100°, which indicates good Super hydrophobic, but HIREC boasts a contact angle of over 150°*1. It is Super hydrophobic making it difficult to keep water droplets on the painted surface.

Features of HIREC Self-cleaning function

Dirt and dust exist in the atmosphere, and when they adhere to Super hydrophobic, Super hydrophobic performance generally decreases gradually.
In addition, as the UV rays contained in sunlight fall on the surface, the coating surface deteriorates and Super hydrophobic performance decreases.
On the other hand, HIREC100 has a self-cleaning function and can be expected to maintain its performance for about 3 years *2.

Main usage scene

(water landing prevention)
(Prevention of snow accretion)
(Measures against falling snow and ice)
(ensuring insulation)

Water landing prevention

Prevents radio wave attenuation due to water film on antennas and radomes when it rains, and prevents droplets from adhering to anemometers and precision instruments

  • Communications (5G, mmWave, LTE, etc.)
  • Weather (X-band, C-band, etc.)
  • Broadcast (satellite TV, etc.)

Prevents snow and ice accretion

Prevent accidents caused by falling snow and ice

Ensuring insulation

Paint insulators, etc. to prevent conduction due to adhesion of seawater and sea salt particles

Oil-water separation

Repels water but not oil
