Road Marking Glass beads Refractive Index

Advantages of SICHENG Glass beads:

1. The chemical composition is inert silicon dioxide and there is no worry about the interference of chemical activity;

2, round elastic particles, impact resistance, can be recycled many times, less loss;

3, the spray wear is small, extend the service life of the nozzle;

4, the surface of the ball, will not damage the processing surface and precision size;

5. After treatment, the work-piece surface is smooth, with a special aesthetic feeling, improving the product value;

6. Suitable for dry and wet sand blasting;

7. The fine glass beads used for the metal micro-cracks can be easily displayed after the wet sandblasting;

8, for the processed work-piece with matte effect, highlighting the metal color, not rust and other advantages, no need to carry out pickling derusting treatment.
