Bentonite
Rheology-modifying bentonite for suspension, viscosity control and thixotropic performance.
Learn MoreDolomite is a carbonate mineral of calcium and magnesium. It is used as a cheap filler, amongst other things.
The table below shows our three dolomite grades, UF2, XF5 and VF10, all supplied as powder with consistent brightness (95). Particle size (D50) increases from UF2 through to VF10, finer grades suit applications where surface finish matters, while coarser grades suit bulk filling.
| Grade | Type | D50, microns | Brightness (SABS 137) | Applications | Stocked In |
|---|---|---|---|---|---|
| DOLOMITE UF2 | powder | 3.5 | 95 | Paint & Coatings Rubber & Plastics Ceramics | JHB |
| DOLOMITE XF5 | powder | 5 | 95 | Rubber & Plastics Ceramics Construction | JHB |
| DOLOMITE VF10 | powder | 10 | 95 | Rubber & Plastics Construction | JHB |
No grades match this application.
Holds steady across all three grades regardless of particle size, so fineness can be chosen without trading off appearance.
Lets formulators pick fineness to match end use, from UF2 for surface-finish-sensitive applications to VF10 for bulk filling.
Dolomite's abundance keeps it economical relative to functional pigments, useful where volume matters more than fine performance.
Contributes durability and low reactivity, a reason it extends into Construction and Ceramics where the paint-focused fillers typically don't.
