Super Hydrophobic Water Repellent & Anti-corrosion Coating Series
NTT-AT HIREC
NTT-AT HIREC®-R / HIREC®-RAS
HIREC®-R
HIREC®-RAS
Description
HIREC®-R is a premium super hydrophobic coating developed by NTT Advanced Technology (NTT-AT), Japan, providing superior water repellency and long-lasting protection for critical outdoor infrastructure. Engineered for harsh outdoor environments, it delivers exceptional water repellency, stain resistance, and reliable protection against rain, snow, and ice.
Featuring an ultra-high water contact angle of over 150°, HIREC®-R allows water droplets to roll off the coated surface, significantly reducing the accumulation of rain, snow, and ice. This helps minimize signal attenuation, prevents performance degradation, and enhances the long-term reliability of outdoor equipment.
Its proprietary self-cleaning surface also reduces the adhesion of dust and airborne contaminants, maintaining excellent hydrophobic performance for approximately three years under outdoor conditions.
HIREC®-RAS is a convenient aerosol-type super hydrophobic coating designed for touch-up and localized repair of surfaces coated with HIREC®-R. Easy to apply without specialized equipment, it quickly restores the hydrophobic performance of damaged or worn coating areas, making field maintenance simple and efficient.

NTT-AT HIREC®-PFW9/ HIREC®-PFS10
HIREC® 450
HIREC® 1450NF
Description
HIREC® PFW9 and HIREC® PFS10 are next-generation PFAS-free super hydrophobic coatings developed by NTT Advanced Technology (NTT-AT), Japan. Designed primarily for indoor applications, they provide outstanding water repellency while complying with evolving PFAS regulations. Featuring an ultra-high water contact angle of over 150°, both coatings effectively repel water, rain, snow, and ice while offering significantly improved visible light transmittance of approximately 40%, compared with conventional HIREC coatings.
HIREC® PFW9 is a water-based coating that is easy to handle, store, and transport, while HIREC® PFS10 is a solvent-based coating that offers faster drying and enhanced durability. Both products require no primer, making application simple and efficient for a wide range of indoor equipment and components.
Features
- PFAS-free super hydrophobic coating
- Ultra-high water contact angle (≥150°)
- Excellent water, rain, snow, and ice repellency
