Benefits

Egress photoluminescent tape is a smooth demarcation tape, used for marking areas in buildings to guide you during power outs or lights out situations. The glow in the dark properties is from photoluminescent powder applied to the base film. When the lights go out, the powder, which is full of photons that store energy from natural or artificial light, release this energy in a bright glow, guiding you down stairways, along walkways and through doorways and exits.

Egress glow in the dark marking tape should only be applied on areas not exposed to foot traffic, due to the nature of the construction, it would degrade quickly from people walking on it. Application on door frames, walls, and edges of walkways is perfect and highlights walking and exit areas very prominently when the lights go out. Even door handles and light switches would benefit from its application.

The luminance of glow in the dark material is measured in millicandelas per square meter ( mcd/m2 ). Measurements of products are judged on how long an afterglow takes to reach 0.32 mcd/m2, which is when it is rendered ineffective. Super takes approximately 450 minutes (7 hours ) to reach to reach 0.32 mcd/m2.

Tape Thickness

High Quality Egress Glow in the Dark Marking Tape features a total applied thickness of approximately 0.015 inches, engineered to deliver dependable visibility and performance without adding excess bulk. Its flexible construction allows the tape to conform smoothly to a wide range of surfaces, ensuring consistent adhesion in both straight and curved applications. Despite its slim profile, this tape provides a durable, long-lasting layer designed to withstand foot traffic and environmental changes, making it an ideal solution for marking escape routes, stair edges, and safety-critical pathways where reliable glow performance is essential.
