Glass beads perform an important function of traffic safety because of their retro-reflective properties. This property allows the motorist to clearly see the pavement line markings more clearly at night and in wet conditions. When a car's headlight beam shines on a pavement marking that is integrated-embedded-saturated with glass beads, the line stripes light up and become much easier to see at night. This effect is called retro-reflection. Paints that have glass beads in them have enhanced night-time reflectivity, higher visibility and safety for the driver.
Glass beads are sold by the 25kgs bags or pallet quantity. traffic marking paint. Glass Beads can be dropped onto many different kinds of non-reflective paints to make them reflective.
Glass beads provide the reflectivity in such products as traffic paint, signs and pavement marking tape. All glass beads are manufactured exclusively from recycled glass products like bottles and windshields. Increased safety in night driving is achieved through the use of tiny glass beads embedded in paint. When millions of these tiny reflective spheres are embedded in highway markings, they shine brightly under headlights, making the marking many times more visible at night than the same markings without reflectorization.
- Increase safety and nighttime visibility
- Increase paint life
- Reduces drying time, tracking and traffic tie-ups
- Application is easy and can usually be accomplished with standard highway marking equipment.
Drop-on Glass Beads, during the process of road work, drop glass bead onto the road line painted with thermoplastic paint which is heated to certain temperature while the paint is still wet, thus to increase the reflectivity of road marking.
How Glass Beads are Applied to Pavement Marking Materials:
The glass beads are applied to pavement marking materials. They can be premixed in marking materials before application, or they can be dropped or sprayed into the wet paint directly behind the paint sprayer, or a portion can be dropped onto premixed two-part epoxy or thermoplastic materials.
The top surface of beads is enveloped by the paint, with the wicking action of the paint rising up to above the midpoint of the bead. This provides two actions. It locks the glass beads into the paint and allows the paint to act as a diffuse reflecting surface for retroreflection, with the paint color affecting the color of the retroreflected light. The light entering the glass bead is bent and focused towards the back of the bead and reflected back out towards the headlights and driver.
