Overview of Intermix Glass Beads
Intermix glass beads, also known as premix glass beads, are microspheres used in road marking materials to provide retroreflectivity. They are embedded in road marking paint to reflect light from vehicle headlights back to the driver’s eyes, thereby increasing visibility during nighttime and adverse weather conditions. These beads are typically made from high-quality glass with precise manufacturing processes to ensure uniformity and durability.

Frequently Asked Questions
Q: What is the raw material of intermix glass beads?
A: Intermix glass beads are usually made from recycled glass.
Q: What is the difference between intermix and drop-on glass beads?
A: Intermix glass beads are pre-mixed with road marking paint, while drop-on glass beads are applied on top of freshly painted road markings. Intermix beads offer longer-lasting reflectivity.
Q: How often should road markings with intermix glass beads be reapplied?
A: Typically, road markings with intermix glass beads need to be reapplied every 1 to 3 years, depending on traffic volume and weather conditions.
Q: What types of road marking paints can intermix glass beads be used with?
A: Intermix glass beads can be used with various types of road marking paints, including water-based paints, solvent-based paints, thermoplastic paints, and epoxy paints.
Q: Are intermix glass beads environmentally friendly?
A: Yes, intermix glass beads are made from inert materials and are non-toxic, minimizing environmental impact.
