Feature:                       

Glass bead reflectivity is the most common way of reflecting light. Thousands of small glass beads embedded in traffic paint will cause it to light up when automobile lights hit it. Because of their shape and clarity, each glass bead reflects light back to the source.
Our reflective glass beads are designed to be added to the surface of traffic paint to make it retro-reflective. The addition of these glass spheres has a dramatic effect on the night time visibility of stripes and markings. Recommended rate of application is 6 pounds per gallon of traffic paint. The beads are to be sprinkled ON TOP of wet paint or hot thermoplastic. They provide a sharp degree of reflectivity in wet or dry conditions. These are the same beads you will see at night on interstate highway lines. The glass beads can also be used in a variety of other applications where reflectivity is desired. Whenever they are distributed on top of wet paint the surface becomes reflective. They have beome very popular in craft type applications.
