Our reflective glass powder is made of tiny glass beads that are sand-like in texture. The powder is used as a coating to create reflective markings for roads, highways, streets, curbs, concrete, parking lots, airports, driveways, pavement marking tape and more. Beads can either be applied to freshly painted surfaces or it can be used with a line striping dispenser to be applied with the paint. These beads can be applied onto water based paint, oil based paint, alkyd coatings, hydrocarbon thermoplastic, methylmethacrylate, and epoxies . Simply sprinkle the glass bead powder over the paint or coating while wet while allowing the beads to sit on top of the coating. Do not cover the beads with your coating or reflectivity will not occur.
