The Characteristics of the Glass Beads

1. The glass beads can scatter light in the full visible spectral range

The glass material is actually colorless and transparent, but because the road glass beads can scatter light in the full visible spectral range, the color looks white. However, when it is added to a colored material, it also diffuses the light of the material color, it can be widely used in any material that requires appearance color without affecting the original material color. So, it is widely used for road marking.

2. The density of road glass beads is small

The density of road marking beads is about one-tenth of the density of traditional filler particles. After filling, the basis weight of the product can be greatly reduced. The larger volume makes it available to replace a large number of other raw materials and reduce product costs.

3. Organically modified (lipophilic) surface

The road marking beads are easy to be wet and dispersed, and can be filled in most thermosetting thermoplastic resins, such as polyester, epoxy resin, polyurethane, and so on.

4. The high dispersion and the good fluidity

Since the road marking beads are tiny round spheres, they have better fluidity than liquid fillers in the form of flakes, needles or irregular shapes in liquid resin, so they will have an excellent mold filling property. More importantly, the micro glass beads are isotropic, so there will be no disadvantages of

inconsistency in shrinkage of different parts due to orientation, which ensures that the size of the product is stable and will not warp.

5. The insulation to heat, sound and electricity and the low water absorption rate

The inside of the road marking bead is a kind of thin gas, so it has the characteristics of sound insulation and heat insulation, and is an excellent filler for various heat insulation and sound insulation products. The thermal insulation properties of the road marking beads can also be used to protect the product from thermal shock, which can be caused by alternating changes between rapid heating and rapid cooling conditions. The high specific resistance and the extremely low water absorption rate make it widely used in the production of cable insulation materials.

The normal temperature type road marking paint and the hot melt type road marking paint

There can be two kinds, the pre-mixed and surface-spread. The pre-mixed glass beads can be mixed in the paint when producing hot melt type road coatings, which can ensure long-term reflection of road markings within the life span.

The other one can be spread on the surface of the marking line to play an instant reflection effect during the construction of the road marking. The road marking beads that has been surface-treated, used in the road marking construction, can improve the adhesion of glass beads to hot-melt markings, and enhance the refractive index of road markings, and can be used for self-cleaning, anti-fouling, and moisture resistance.
