About Reflective Glass Beads: frequently asked questions?
Can I mix the beads into the paint?
No, beads must be the first thing to receive light in order to reflect. Glass Beads are retro reflective meaning they reflect light directly back to the light source. You see the reflection only when your eyes are at the same level as the light source. (like car headlights)
Why are the glass beads not reflecting?
Glass Beads are retro reflective meaning they reflect light directly back to the light source. You see the reflection only when your eyes are at the same level as the light source. (like car headlights). If the beads are not reflecting properly please ensure they are not covered by a clear coat or any other medium. Also be sure not to press down beads into the paint. One trick is to take a flash picture with your phone or camera. (retro-reflection, flash is the source)
Why so many types of beads?
The roundness, size, clarity affect the reflective properties of beads. Larger beads allow the eye to see the retro reflection at wider angles. Smaller beads are great for signs. High Index reflective glass beads are Type 3 beads and have near perfect clarity, uniformed size, roundness and perform about 5-6 times brighter than Type 1 beads (Standard DOT, Airport Quality, Powder and Large Deco molded beads)
