Характеристики

Ключевые свойства и преимущества

Superior Water Resistance: Designed with hydrophobic segments that minimize moisture sensitivity and prevent leaching in cured films.
High Pigment Loading: Enables the formulation of high-solids concentrates while maintaining excellent flow and pumpability.
Enhanced Color Strength: Optimizes particle size distribution for maximum tinting strength, gloss, and transparency.
Robust Steric Stabilization: Prevents flocculation and sedimentation even under high-temperature storage conditions.
VOC Compliance: Low-to-zero VOC profile, making it suitable for environmentally regulated and eco-labeled coating applications.
Excellent Substrate Wetting: Improves the coverage and adhesion of the coating on difficult, low-energy surfaces.

Спецификации

Технические особенности

Polymer Architecture: Controlled block or graft copolymer structure with optimized molecular weight distribution for maximum efficiency.
Stabilization Mechanism: Employs a dual-mode approach combining electrostatic repulsion with long-chain steric hindrance.
Hydrophobicity Index: Significantly lower moisture vapor transmission rates (MVTR) compared to standard sodium polyacrylate dispersants. pH Versatility: Maintains high performance and structural stability across a broad pH range, typically between 7.0 and 10.5.
Interaction Efficiency: High affinity anchoring groups ensure minimal free dispersant remains in the aqueous phase, reducing foaming tendencies.
Resin Compatibility: Demonstrates broad miscibility with acrylic, polyurethane (PUD), and waterborne epoxy binders.
