Reddit reviews JVCC REF-7 Engineering Grade Reflective Tape: 1/2 in. x 30 ft. (Yellow)

JVCC REF-7 Engineering Grade Reflective Tape is used for safety applications as well as entertainment industry use as spike tape or "daytime" glow tape. Reflective Tape is primarily designed for permanent and temporary traffic signage and features an enclosed lens retroreflective urethane film coated with a permanent acrylic adhesive.Application surface should be flat (not curved or tubular). Also, it is not designed to adhere to unpainted stainless steel surfaces. JVCC REF-7 may be screen printed, guillotine cut, die-cut, or thermal kiss-cut. The adhesive has a dwell time of 24 hours but reaches 75% of its adhesiveness after 15 minutes.Photos of REF-7 are taken with a flash camera in order to show the reflectivity of the tape; the colors of the tape will be much darker if a high-intensity light source (like the flash from a camera or car headlights) are not being directed at the tape. The colors in order of reflectivity are: white, yellow, orange, green, red, blue (white is around 15 times more reflective than blue).Certifications: LS-300C (Reflectivty 1 Class 1), FP-85 (Type II), ASTM D4956-94 (Type 1). Carrier/Backing: enclosed lens retroreflective urethane film. Adhesive: acrylic. Adhesion: 50 ounces per inch (to stainless steel test panel).Thickness: 12.8 mils (carrier, adhesive, liner) 6 mils (carrier, adhesive) 6.8 mils (liner) . Service/Operating Temperature: -40F to 180F.
