Daohong glass beads have been used as reflex beads for road markings for over 20 years. They serve as a retroreflection medium, the incident headlight of the vehicle is reflected inside the glass spheres and returned to the observer in the vehicle as a beam of light, so that the road markings are clearly visible even at night or in poor light conditions. We have specialised in high-quality reflex glass beads, which are especially designed to maintain night visibility even on wet roads with a water film covering the marking.
Available sizes of our Daohong Glass Beads range from 0.4mm to approx. 1.5mm; on demand even larger.
High Index Reflective Glass Beads for road markings can improve the reflective performance of road marking paint. The light of the car lights on the marking lines with glass beads, which can reflect the light of the car lights back, make the driver see the direction of travel, and improve the safety of driving at night.
High Index Reflective Glass Beads are a kind of fine glass sphere formed by melting glass sand (waste glass) at high temperatures. Glass beads for road marking are spherical under the microscope, colorless, transparent, and the refractive index is 1.5-1.64. Between 44 and 1400 microns in diameter.
Daohong reflective road paint beads use the window glass, the color is white and clean, reflective micro glass beads will give good performance when used on marking line, the roundness is more than 80%, to promise the reflectivity.
Glass beads for road marking are widely used on city road lines, highway pavement, and Guardrail outlines.
With many years of experience in the manufacturing of reflective road paint beads, We have mature solutions of glass beads for paint, such as Intermix glass beads, Drop On Glass Beads, High Index Reflective Glass Beads. The National standard of GT, BS6088, EN1424/1423, and AASHTO guarantee the quality of our glass beads for road marking.

Reflective road paint beads play a necessary part in traffic safety because of their retro-reflective properties. This property lets in the motorist to truly see the pavement line markings greater truly at night and in moist conditions. When a car's headlight beam shines on a pavement marking that is integrated-embedded-saturated with reflective glass beads powder, the line stripes light up and come to be plenty less complicated to see at night. This effect is called the retro-reflection. Glass beads for road marking paint can be divided into two types: the intermix type and drop on, and the intermix type, which should be added directly in the road marking paint, and stir together. While, the drop on type is drawn in the pavement marking, not directly sprayed over the dry coating reflective micro glass beads.
As a glass beads for road marking manufacturers, our reflective road paint beads are sold by using the 50-pound or 25kgs plastic bag or jumbo bag. The common utility will require 5-7 pounds of reflective road paint beads per gallon of USSC traffic marking paint. Reflective micro glass beads can be dropped into many special kinds of non-reflective paints to make them reflective.
