Bentonite
Rheology-modifying bentonite for suspension, viscosity control and thixotropic performance.
Learn MoreAlso known as talcum powder, this magnesium silicate mineral is used in paint, plastics, cosmetics and many other day-to-day items. It is known to be the softest mineral with hydrophobic properties.
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 45µ and 106µ 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.
