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 |
|---|---|
| High Efficiency | Reduces grinding time and energy consumption. |
| Broad Compatibility | Suitable for multiple resin systems (acrylic, epoxy, PU). |
| Low Dosage | Effective at 0.5–3% (based on total solids). |
| Eco-Friendly | Low VOC; meets REACH/EPA standards. |
Usage Guidelines
| Parameter | Recommendation |
|---|---|
| Dosage | 0.5–3% of total formulation weight. |
| Addition Point | Add during grinding/pre-dispersion phase. |
| Storage | Keep sealed at 5–35°C; shelf life: 12 months. |
