HIREC Series: Super Repellent Material
HIREC was developed to protect NTT's telecommunications equipment from snow, ice or water-related damage, thereby facilitating the maintenance of stable communications.
The super water-repellent material HIREC, developed by NTT Advanced Technology Corporation, is a dramatic new concept in the field of water-repellent materials.
Up until now, water-repellent coatings afforded a maximum contact angle between an object and water droplets of approximately 100°. The Super Water-Repellent Material HIREC provides a contact angle of 150° or more, resulting in higher performance and long-term stability. On top of that, this breakthrough coating also demonstrates superior effectiveness in preventing adhesion of snow, ice, and other substances besides water. The Super Water-Repellent Material HIREC is expected to contribute to higher performance and durability, while maintaining the attractiveness of products in a wide range of fields, particularly communications equipment.
The most important feature of the Super Water-Repellent Material HIREC is that it keeps water away. Super water-repellent properties are completely different from the properties of waterproofing that prevent water from permeating. HIREC repels water and shows excellent water-repellent properties with a contact angle of 150° or more between an object and water droplets. When water droplets fall on HIREC-coated surfaces, they instantaneously disperse into smaller droplets, as if they are repelled. The water droplets remaining on the coated surfaces are round and maintain a spherical shape as if they are standing-up. These excellent properties of HIREC are expected to bring a wide range of benefits to various industries and everyday life.
The Super Water-Repellent Material HIREC is effective in preventing snow and ice from sticking to surfaces and is also effective in preventing the formation of icicles. In snowy regions where snow and ice cause hazardous conditions, the super water-repellent material HIREC can be counted on as a very effective solution.
