The drop on glass beads will be evenly spread on the surface of the hot-melt paint at a certain ratio through the spray gun of the marking machine at the same time as the marking line construction.
Road marking glass beads are mainly used in normal temperature and hot melt road marking paints.
We produce different standard drop on glass beads for road marking according to customer requirements, what we know the standard is BS6088A/B, EN1424/1423, AASHTO type1/type2, and so on.
The specific gravity of drop on glass beads: 2.4-2.6g/cm3
Glass bead refractive index: ≥ 1.50
The roundness of glass beads: ≥80%
Magnetic particle content: ≤0.1%
The overall appearance of the glass beads is required to be colorless.
Loose spherical particles, clean and free of impurities,
Not contain an Agglomerate
In the road paint production process, the drop on glass beads is dropped or sprayed into the wet paint directly according to the weight ratio of 18-25% (refer to the Chinese transportation industry standard JT/T280-2004, different national and regional have different standards).
Drop on Glass 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 drop on glass beads, the line stripes light up and come to be plenty less complicated to see at night. This effect is called the retro-reflection.
We are engaged in offering a comprehensive range of drop on glass beads used for that immediate shine on the just laid road marking line. We assure you to consistently supplying a good quality drop on glass beads as per the specific requirements of our clients. These drop on glass beads are known for cost-effectiveness and impressive appearance. These are specially coated for reflectivity and durability.
