Glass Sandblasting with Silicon Carbide
Overview
Silicon carbide (SiC) is an excellent abrasive for glass sandblasting and etching applications. Its sharp, angular grains ensure precise control and consistent surface texture, allowing for both decorative and functional finishing on glass surfaces.
Green silicon carbide, in particular, provides high cutting efficiency while minimizing chipping or micro-cracking, making it ideal for architectural glass, mirrors, and decorative panels.
Application Scenarios
- Decorative Etching: Produces fine patterns and frosted textures on glass artworks and architectural panels.
- Frosted Surface Finishing: Used for anti-glare or privacy glass in interior and exterior designs.
- Pre-Coating Surface Preparation: Enhances coating adhesion for mirrors, solar panels, and optical components.
- Textured Glass Production: Ideal for producing uniform matte finishes with high visual quality.
Recommended Product & Grit Sizes / Grades
Green silicon carbide powders are preferred for glass sandblasting due to their purity and sharpness. The grit size selection depends on the depth and smoothness of the desired etching effect.
| Application Type | Recommended Product | Typical Grit Size |
|---|---|---|
| Deep etching / rough texture | Green Silicon Carbide | F46 – F80 |
| Medium-depth etching | Green Silicon Carbide | F100 – F150 |
| Fine surface finishing | Green Silicon Carbide | F180 – F320 |
