Характеристики

Ключевые свойства и преимущества

Dual-System Versatility: Seamlessly transitions between water-borne and solvent-borne systems, reducing inventory complexity for diverse manufacturing requirements.
Enhanced Coloristic Properties: Maximizes pigment tinting strength and transparency, ensuring vivid color development even with challenging organic pigments.
Rheological Optimization: Effectively lowers millbase viscosity, allowing for higher pigment loading and significantly reduced grinding times during processing.
Anti-Flocculation Stability: Provides robust steric stabilization, preventing pigment re-aggregation and ensuring excellent long-term storage stability without settling.
Surface Aesthetics: Improves leveling and surface gloss while minimizing defects like flooding, floating, or Benard cells in final film applications. This agent delivers superior intercoat adhesion and scratch resistance to coatings.

Спецификации

Технические особенности
