Shedding Some Light on Reflective Markers
3M Engineer Grade reflective is the most common choice within Electromark’s reflective materials family. It comes in many colors, conforms to most surfaces, resists removal, delivers 7-year plus life and costs less than other “family” options. Typical acrylic adhesive sets up fast and bonds permanently. Engineer Grade uses glass-bead construction: embedded microscopic beads with metallized coating that reflects light back to the source. Economical Engineer Grade’s wide usage in reflective marking includes: general facility and safety signs, voltage and pipe markers, hard-hat labels, floor tapes, demarcation strips, traffic control markings and much more. Engineer Grade meets US DOT specs for construction of Roads & Bridges on Fed Highway Projects FP-85.718-1989 Type II Class 1 or 2 and GSA LS-300C Reflectivity 1, Class 1 or 2.

3M High Intensity reflective enhances glass-bead technology to deliver reflectivity ratings 3 times higher than Engineer Grade. Its thick, quick-setting, twice-as-strong acrylic adhesive also adheres permanently to more surfaces than EG (e.g., low surface-energy plastics). High Intensity markers will perform for 10-years plus in typical applications such as pedestals, poles and roadway-work gear. Meets US DOT specs for construction of Roads & Bridges on Fed Highway Projects FP-85.718-1989 Type IIIA Class 1 and GSA LS-300C Reflectivity 2, Class 1.

SunBright® High Intensity reflective uses new Microprism technology for truer color and greater visibility. Three times Engineer Grade’s reflectivity, it outperforms at greater distance, wider angle and lower light source by reflecting from interior surfaces of microscopic prisms—with lower loss of light energy. This enables SunBright®’s yellows, whites or oranges to seem brighter and truer hued than Engineer Grade or High Intensity reflected colors.

3M™ Scotchlite Diamond Grade Conspicuity Sheeting is a highly retro-reflective material designed to mark vehicles for enhanced visibility and detection. It is also good for school crossing and most workzone warning signs. Diamond Grade employs prismatic lenses formed in a transparent resin, sealed and backed with a pressure-sensitive adhesive and clear poly liner. Diamond Grade achieves reflectivity ratings 9 times greater than Engineer Grade and 3 times greater than either High Intensity or SunBright® materials. Fluorescent versions offer the ultimate in visibility. To learn more about reflective, fluorescent and photoluminescent materials, see www.Electromark.com/materials.asp.
