Brady B309 is High Intensity Prismatic Reflective Sheeting with black characters bordered with photoluminescent (glow‑in‑the dark) material and backed with a pressure sensitive adhesive. Brady B309 is used for general labeling; designed for permanent applications indoors as well as severe outdoor environments. Special acrylic adhesive adheres strongly, making marker removal difficult. The ultra‑reflective technology allows for maximum visibility from a greater distance, wider angle and lower light source than standard reflective vinyl, while the photoluminescent boarder gives the character distinct definition in blackout conditions
