The 6640 Waterborne Wetting and Dispersing Agent represents a sophisticated chemical solution engineered for the high-performance stabilization of pigments within aqueous systems. Utilizing advance…
Provides exceptional stabilization of organic pigments and carbon black through high-molecular-weight steric hindrance.
Significantly reduces mill-base viscosity, enabling higher pigment loading and shorter grinding times for increased production throughput.
Enhances color strength, transparency, and gloss while effectively preventing flooding and floating during the application process.
Exhibits excellent compatibility with common waterborne binders, including acrylic, epoxy, and polyurethane dispersions, ensuring formulation flexibility.
VOC-free and APEO-free composition aligns with stringent environmental regulations and sustainable manufacturing standards.
Improves storage stability by maintaining consistent viscosity and preventing pigment sedimentation over extended periods.
规格
技术亮点
Chemical Composition: Solution of a high-molecular-weight block copolymer containing multiple pigment-affinic functional groups.
Solid Content: Typically ranges between 35% and 45%, providing a concentrated active ingredient for cost-effective dosage.
Ionic Character: Non-ionic/anionic nature ensures broad compatibility across various pH ranges and complex resin systems.
Stabilization Mechanism: Predominantly steric stabilization, which is more robust against electrolyte sensitivity than purely electrostatic methods.
