Характеристики

Ключевые свойства и преимущества

Advanced steric stabilization prevents pigment re-agglomeration in low-viscosity systems.
Significant reduction in mill-base viscosity for optimized industrial processing speeds.
Enhanced pigment loading capacity in concentrated pigment pastes and masterbatches.
Superior color development and increased transparency for high-end organic pigments.
High gloss retention and improved leveling properties in final cured films.
Excellent compatibility with solvent-borne resins such as PU, epoxy, and CAB.
Robust thermal stability during high-speed dispersion and long-term shelf storage.
Reduces flocculation and flooding or floating issues in multi-pigment formulations.
Lowers energy consumption by shortening grinding and dispersion cycles significantly.
Highly effective at lower dosage levels compared to conventional wetting agents.

Спецификации

Технические особенности
