The table below shows our two silica grades, both supplied as powder with 98.5% SiO₂ purity. Use the mesh size and particle size (% passing the stated micron cut) to match the texture and coarseness your formulation requires — 325 Mesh (45µ) gives a finer texture than 150 Mesh (100µ). Both grades are suited to textured paints.
| Grade | Type | SiO₂ (%) | Particle size | Applications | Stocked In |
|---|---|---|---|---|---|
| 325 Mesh (45μ) | powder | 98.5 | 93%<45μ | Textured Paints | JHB |
| 150 Mesh (100μ) | powder | 98.5 | 93%<106μ | Textured Paints | JHB |
Minimal impurities support consistent colour and performance across batches.
Silica's natural hardness (Mohs 7) contributes durability and texture retention in coatings that see wear.
The 325 and 150 Mesh options let formulators dial in surface texture and roughness precisely for textured paint applications.
Stable and unreactive with binders and resins, supporting long-term formulation stability.
