H2 DetecTape™ is a chemochromic (color changing) selffusing silicone tape designed to detect hydrogen gas (H2) leaks in fuel cell, transmission, storage, and generation facilities. When in contact with concentrated hydrogen gas, the tape color changes from light gray to dark black in the event of a leak due to vibration or seal failure.
