PERMALIGHT® product installed on the International Space Station

In an effort to reduce maintenance costs of the battery powered emergency egress guidance system on the International Space Station (ISS), NASA evaluated a more cost efficient photoluminescent system with regards to effectiveness, reliability and durability.
American Permalight's photoluminescent high performance PVC complies with all of the stringent NASA requirements and was accepted for the installation on the ISS.
Our PVC product with a luminance of 600/90 mcd /sqm. was processed into circular discs in different sizes that were then installed using a long-duration adhesive.The markers were placed around the hatch ways of Node 1, Node 2, Node 3, the U.S. Lab and Permanent Multipurpose Module and enable crew members to identify the egress path in sudden darkness and during a power blackout.

The installation of further markers for modules of international partners is planned before the end of the year.
