Key Properties & Functions
| Property | Description |
|---|
| Dispersion |
Stabilizes solid particles (e.g., pigments, fillers) in liquid media, preventing agglomeration. |
| Compatibility |
Works with aqueous and solvent-based systems (paints, coatings, inks). |
| Thermal Stability |
Stable up to 200°C; suitable for high-temperature processes. |
| Ionic Nature |
Anionic/nonionic hybrid enhances compatibility with varied formulations. |
| Foam Control |
Low-foaming formulation for industrial applications. |
Applications
| Industry | Use Case |
|---|
| Coatings |
Improves pigment dispersion in waterborne/ solvent-based paints. |
| Inks |
Enhances color strength and printability. |
| Ceramics |
Disperses inorganic powders in slurry preparations. |
| Construction |
Reduces viscosity in cement/polymer-modified mortars. |
| Oilfield |
Prevents particle sedimentation in drilling fluids. |
Performance Advantages
| Advantage | Benefit |
