Характеристики

Ключевые свойства и преимущества

Exceptional pigment wetting capabilities reduce grinding time and energy consumption during the manufacturing process.
Optimizes color strength and transparency for high-performance organic pigments and carbon blacks.
Provides outstanding long-term viscosity stability, preventing gelling or pigment settling in stored formulations.
Enhances coating properties, including increased gloss, improved leveling, and reduced haze in clear-coat systems.
Universal compatibility with various water-thinnable resins, including PUDs and waterborne acrylic emulsions.
Environmentally compliant formulation is free from alkylphenol ethoxylates (APEO) and volatile organic compounds (VOC).
Reduces water sensitivity in dried films, maintaining superior humidity and corrosion resistance.

Спецификации

Технические особенности

Chemical Nature: High molecular weight block copolymer with pigment-affinic groups (typically ammonium salt).
Active Content: Approximately 40% to 50% non-volatile matter optimized for aqueous delivery.
Solvent System: Water-based medium, ensuring low odor and ease of incorporation into cold blends. pH Range: Stable performance across a broad pH spectrum, typically effective between 7.0 and 9.5.
Density: Approximately 1.04 to 1.08 g/cm³ at 20°C, facilitating accurate volumetric dosing.
Lowered Surface Tension: Significantly reduces dynamic surface tension to improve pigment penetration and air release.
Anchoring Groups: Multiple amine-based or acidic anchoring sites ensure irreversible adsorption.
