Intermix glass beads are small, spherical glass particles that are used as an additive in thermoplastic road marking paints. These paints are applied to roads, highways, and other paved surfaces to provide visual guidance and demarcation to drivers and pedestrians. The glass beads are mixed into the paint before it is applied, and they serve several important functions:


Reflectivity: The glass beads in the paint reflect light back to the source, making the painted lines and markings more visible to drivers at night or in low-light conditions.

Durability: The glass beads help to strengthen the paint film and make it more resistant to wear and damage from traffic, weather, and other environmental factors.

Skid resistance: The glass beads can also help to increase the skid resistance of the painted surface, improving safety for drivers and pedestrians.

Intermix glass beads are typically used in high-quality, premium thermoplastic road marking paints, as they are known for their consistent size, shape, and reflective properties. They are also used in other types of reflective coatings and paints, such as those used on signs, markings, and other traffic control devices.

Intermix glass beads are particles that are mixed in during the production of hot-melt coatings. Intermix glass beads are also called premixed beads.


The mixed glass beads produce a constant reflectance throughout the life cycle of the marking line. The road marking material wears away with the passage of time. The glass beads for road marking mixed in the material leak on the surface, thereby maintaining a high inverse setting coefficient.
