Sandblasting Grade Glass Beads With High Roundness
Introduction
Micro glass beads are the core part for the production of reflective materials like reflective fabric, reflective sheeting, reflective ink, reflective marking paint,reflective clothing and extended products.
High refractivity glass bead owns unique retroreflecticity property. Glass bead is a kind of micro structure reflective material that can return light(>85%) to the original light source after focusing by the refraction layer. The returned light formed by retroreflection can help driver or outdoor workers with light source identify obstacle and take measures in advance to ensure safety at night or in low light conditions.

Quality Standard:
1. The appearance is clean, transparent and free of impurities;
2. The bubble content in the glass beads is less than 10%;
3. The magnetic particles do not exceed 0.1% of the product weight;
4. Does not contain any silicone resin ingredients;
5. Rounding rate ≥90%
Application areas:
Reflective glass beads are the basic material of road marking coatings, mainly used for road markings (heat capacity paint premixed and sprinkled on the construction surface) signs, barrier outline signs, handicraft beads, etc.
Coated glass beads use a high-performance organic silicon material to externally treat the glass beads. After the glass beads are coated, the strong polar groups on the surface become non-polar groups, so that the surface of the glass beads can absorb dust in the air. The phenomenon weakened.
Since the coated beads contain a specific coupling agent, the adhesion between the microbeads and the coating can be improved and some small glass beads can be prevented from being deposited in the coating. The performance of glass beads is even better after coating.
