Характеристики

Ключевые свойства и преимущества

Superior Pigment Wetting: Dramatically reduces grinding time by accelerating the displacement of air and moisture at the pigment surface.
Enhanced Color Development: Maximizes tinting strength and transparency by ensuring a narrow particle size distribution during the milling process.
Improved Gloss: Promotes a smooth, uniform film surface, significantly increasing specular reflection and DOI in architectural finishes.
Formulation Versatility: Exhibits excellent synergy with associative thickeners, allowing for precise rheology control without compromising stability.
Environmental Resistance: The polymer backbone offers better water and scrub resistance compared to polyacrylate-based dispersants, extending the lifecycle of the applied coating and durability in harsh outdoor weathering environments.

Спецификации

Технические особенности

Chemical Composition: Styrene-Maleic Anhydride (SMA) copolymer ammonium salt with an optimized monomer ratio for balanced hydrophobicity.
CAS Verification: The ammonium salt of SMA copolymer is identified under CAS No. 52256-69-6, ensuring regulatory compliance for industrial applications.
Molecular Weight: Engineered with a specific medium molecular weight to balance effective adsorption and steric hindrance without increasing system viscosity.
