Description of Clay
RBL supplies high-quality Hydrous and Calcined Clays. Sourced from selected deposits and processed under controlled conditions, these clay products are widely preferred as cost-effective extenders and partial replacements for TiO₂ in paint and coating applications.
RB GLAZE (Calcined Clay)
Calcined Kaolin providing high whiteness, brightness, and excellent opacity along with superior scrub resistance for interior and exterior paints. RB Glaze acts as an effective extender and can be used for partial replacement of TiO₂ in various paint formulations.
| Characteristics | Specifications | Unit |
|---|---|---|
| Whiteness | 96.5 - 97.5 | % |
| Brightness | 94 - 95.5 | % |
| Residue on 500# | 0.01% Max. | % |
| PSD D50 | 2 Max. | μ |
| PSD D97 | 15 Max. | μ |
| Oil Absorption | 75 - 85 | g/100g |
Key Benefits
- Cost reduction through partial replacement of TiO₂ in interior and exterior paints.
RB GLOSS (Hydrous Clay)
A hydrous clay with fine and narrow particle size distribution. It is highly effective in providing enhanced gloss, opacity, and smooth finish in paint formulations.
| Characteristics | Specifications | Unit |
|---|---|---|
| Whiteness | 88.50 - 93.50 | % |
| Residue 325 Mesh | 0.00 - 0.01 | % |
| Hegman Grind | Minimum 6.5 - 7.0 Max. | - |
| pH of 28w/w Aq. Slurry at 25°C | 6.00 - 8.00 | - |
| Volatile Matter | 0.00 - 1.0% Max. | % |
Key Benefits
- Recommended for oil-based high gloss paints and water-based paints.
- Highly effective for partial replacement of TiO₂, reducing formulation cost.
Applications
- Used as extender in interior and exterior paints.
- Rheological additive for controlling viscosity.
- Imparts gloss to paint.
