and the main safety ingredient in all our product line. Adding Retro-reflectivity to road marking paints is a major factor in increasing road safety in a very cost-effective way. Our glass beads exceed all federal & international standards for roundness, granularity and retro-reflectivity.
sarmac glass beads are known for purity & roundness - features that make up for good, reliable reflectivity, but when we enhance our production processes with continuous research & development, we specify new glass beads offerings with a refractive index no less than 1.55, taking reflectivity, thus road safety, to a higher level.
