The main characteristics  of coating glass beads are probably as follows:
1. The chemical composition is inert silica, no chemical activity interference concerns;
2. Round elastic particles, impact resistance, can be cycled many times, less loss;
3. Small wear to spray and prolong the service life of nozzle;
4. The spherical surface will not damage the machined surface and precise dimensions;
5. After treatment, the surface of the workpiece is smooth and has a special beauty, which improves the value of the product;
6. Suitable for dry and wet sandblasting operations;
7. Metal micro-cracks are easily displayed after wet sandblasting with fine glass beads;
8. For the processed workpiece, it has a matte effect, highlights the metal color, does not rust, etc., without the need for pickling and rust removal. Uses:
 
The main usages of glass bead :
1. Beading aerospace parts to eliminate their stress to increase fatigue strength and reduce friction and wear;
2. Sand blasting, rust removal, paint removal, carbon removal, and machining tool marks;
3. Treatment before anodizing and electroplating can increase adhesion in addition to cleaning;
4. Aesthetic processing such as welding bead cleaning and surface scratch removal of stainless steel workpieces;
5. Cleaning and derusting of wire cutting molds;
6. Decontamination of rubber molds;
7. Road markings are used for reflection;
8. For the exterior decoration of artworks; shape: spherical.
