Product Description
Road marking glass beads are mainly used in normal temperature and hot-melt road marking paints. They can be classified into Drop-on and Intermix.
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.
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 intermixed 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
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).
We produce different standard drop on glass beads for road marking according to customer requirements, and what we know the standard is BS6088A/B, EN1424/1423, AASHTO-m247, and so on.

FAQ
How to Use Gangde Glass Beads for road marking
Reflective glass beads can be classified into Drop-on and Intermix.
As the marking line construction, 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.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.
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 intermixed 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
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).
The effect of defective rate on retroreflection coefficient?
The defective rate is in accordance with the European standards, and refers to non-shaped, out-of-round, deformed, severe air bubbles, etc., which are called defective products. The defect rate of the product affects the light reflection efficiency. The lower the defect rate is, the higher the light reflection efficiency is. On the contrary, scattering phenomenon will occur, resulting in lower reflection efficiency. The retroreflection coefficient is the numerical expression of the reflection efficiency through the retroreflection tester.
The effect of particle size distribution on reticle?
The particle size distribution of the product should follow a scientific ratio and strictly abide by government standards. It has an excellent settling rate during use, and can show an excellent inverse value. At the same time, because the particles are uniform and the settling rate is stable, it can prolong the retroreflection life of the marking.
What is the difference between retroreflection coefficient and refractive index?
Many users often ask about the refractive index of glass beads. The refractive index is a characteristic of the material of the glass itself. Generally, the refractive index is divided into low refractive index, medium refractive index and high refractive index. The glass we usually use for marking lines belongs to the low refractive index category. The refractive index is greater than or equal to 1.50 (some inferior manufacturers choose inferior glass raw materials with a refractive index lower than 1.50). Under the same conditions, the higher the refractive index is, the higher the retroreflection coefficient is.
Why is the retroreflection coefficient of the marking line unqualified?
The retroreflection coefficient is affected by many factors; thickness ,whiteness of the marking line and spreading amount, roundness, light transmittance, particle size distribution, and refractive index of glass beads. Indicators such as these will affect the final retroreflection coefficient of the marking line. For example, Party A requires the retroreflection coefficient to be greater than 250, but the user chooses cheap products, and the phenomenon that the retroreflection coefficient cannot meet the standard is bound to occur.
How much retroreflection factor can your high-brightness glass beads achieve?
First of all, as mentioned in the previous introduction, the retroreflection coefficient of the marking line is affected by many factors. GANGDE H series high-brightness glass beads are not high-brightness glass beads that simply improve the roundness as claimed by some manufacturers. We purify the glass and the glass beads itself through optical principles, and add a high-brightness factor to improve the light reflection efficiency to achieve higher brightness of high-quality glass beads. When using our H-series high-brightness glass beads under other excellent conditions, the retroreflection coefficient can exceed 450 when the spreading amount is 400 g/square meter; some experienced users can easily exceed 500;
