1) Product Function
  Improve the road marking line contrary reflection function. When driving at night, the lamp shines on the marking line with glass bead in it, the ray of lamp is reflected back parallely. So the driver can look at the road clearly and drive safely at night.
2) Product Specification:
    The main products:
    1.No.1-3 beads size distribution according to JT/T 446-2001 Standard of Chinese Traffic Ministry.

① Product Introduction
    The coated glass bead have been treated with high quality organic materials on their surface, thus bearing better features in quality. Our company has developed this unique product after absorbing advanced technology from foreign countries and it has the following advantageous features:
A The contrary reflexible of the micro glass beads maintains since we select the materials which are similar to the nature of micro glass beads.
B In rainy and wet weather, ordinary glass beads would be surrounded by water and result in th low reflection rate. However, the micro beads with coated can maintain the reflection effect to a great extent.
C Ordinary glass beads would pile up in the sprayer after absorbing water. However, micro beads with coated would not so, thus increasing the working efficiency.
D since micro beads with coated contain special adhesives, thus improving the integrity between the micro beads and the paints.
E Can prevent sinking of micro beads to the bottom of paints.
F after the treatment of coated thus absorbing less dust from air.

② Product specification
Coated can be done from 50μm-1180μm, based on clients requirements.

③ Technical references
Appearance: beads with round ball shape and no visible impurity.
Refractive index:＞1.5
density:2.4-2.6g/cm3
SiO2 content:≥68%
size distribution and spherical beads.
Water resistance: when the wastage of 0.1N hydrochloric acid is 10ml, the surface of glass bead does not fade.
Coated feature: After soaking in water for 30 seconds and dry for 2 hours under in-door temperature, they can easily pass through filler while shaking slightly.
