Presentation Title: 
Superhydrophobic coating complying with the PFAS restrictions trends

Presentation Abstract: 
Organic fluoride (so-called PFAS) are valued and widely used across many industries due to their chemical stability and excellent hydrophobicity. However, In recent years, concerns have grown over the long-term persistence of these substances in the natural environment and the human body, leading to the initiation of international regulatory discussions. Among them, PFOA, PFOS, and PFHxS are considered highly likely to cause cancer and are banned under the POPs Convention.

NTT-AT’s HIREC is superhydrophobic coating which possesses superhydrophobicity with an initial water contact angle of 150 degrees. Due to its exceptionally high performance, HIREC has been used in numerous outdoor facilities worldwide. Importantly conventional HIREC does not contain those banned substances such as PFOA, PFOS and PFHxS.

In response to evolving regulations and growing market demand for environmentally responsible materials, NTT-AT has closely monitored market trends and proactively pursued the development of a PFAS-free HIREC.

In October 2025, NTT-AT announced an advanced version of HIREC that is entirely PFAS-free and added to our product lineup.

This newly developed coating achieves superhydrophobic performance equivalent to that of the conventional product, maintaining an initial water contact angle exceeding 150°, while being environmentally friendly and safe for human health. In addition, the new formulation exhibits improved light transmittance compared with conventional HIREC coatings, thereby expanding its potential range of applications.
