Core Advantages
1. Efficiently wets and deflocculates pigments, reduces grinding viscosity and improves production efficiency;
2. Enhances tinting strength and film gloss, inhibits pigment flocculation, sedimentation and coarsening;
3. Perfectly protects aluminum silver pigments, optimizes pigment orientation and prevents darkening & gloss loss;
4. Solvent-free, amine-free and APEO-free, compatible with solvent-based, 2K solvent-free and UV-curing systems;
5. Optimal performance when added during the grinding stage.
Main Application Fields
Core Applications: Solvent-based pigment concentrate paste, UV ink color paste, aluminum paint formulation
Compatible Fields: Wood & industrial paint, packaging printing ink, filler filling system
Prohibited Scenarios: Food contact products; not recommended as primary dispersant for water-based systems.
