Product Features
- Excellent dispersibility: Anchoring groups strongly adsorb onto pigment surfaces, while solvated chains create steric hindrance to prevent long-term flocculation.
- Significantly reduce viscosity and boost efficiency — increase solid content in pastes/granules, cut grinding energy consumption, and shorten processing time
- Anti-flocculation and anti-coarsening: maintains stable pigment paste during long-term storage without flocculation or coarsening.
- Broad applicability — excellent dispersion for organic pigments, inorganic pigments, carbon black, and titanium dioxide.
- Boost Color Strength — Fully dispersed pigments can improve color strength by 10-30%.
- Excellent resin compatibility — suitable for epoxy, polyester, acrylic, polyurethane, and plastic systems.
Application Areas

App Data
| Applicable Systems | Recommendation | Behavior Description |
|---|---|---|
| Industrial Coatings | ✅ Recommended | Use 0.1% to 1% of the pigment amount for dispersion, viscosity reduction, and anti-settling. |
| Ink | ✅ Recommended | Use at 8-20% of pigment weight for dispersion and anti-agglomeration. |
| Plastic Masterbatch | ✅ Recommended | Use 3-10% of the pigment amount for pre-dispersion and color enhancement. |
| ink paste | ✅ Recommended | Dosage: 5-15% of pigment weight; disperses well and remains stable over time. |
| Cosmetic Pigments | ⚠️ Use with Caution | Usage: 5-10% of pigment loading, dispersion and fineness |
| Ceramic Pigments | ⚠️ Use with Caution | Use at 3-8% of pigment weight for dispersion and anti-settling. |
Notes
- Please test with a sample first to confirm the optimal dosage and heat resistance conditions.
- The powder color chart may differ from the final product color. Please refer to the actual colored result.
- Evaluate weather resistance for long-term outdoor exposure.
