The 6271 Waterborne Polymer Dispersant represents an advanced solution in the field of high-performance coating additives, specifically engineered to address the complexities of pigment stabilizati…
Superior Color Development: Maximizes pigment tinting strength and ensures vivid color expression across diverse organic and inorganic pigment types.
Excellent Stability: Provides exceptional anti-flocculation properties and prevents viscosity drift and sedimentation during long-term storage of concentrated dispersions.
Broad Compatibility: Seamlessly integrates with various waterborne resins, including PUDs, acrylic emulsions, and traditional water-reducible alkyd resin systems.
Enhanced Gloss: Significantly improves the surface gloss and DOI (Distinctness of Image) of final coating films upon dehydration.
Efficient Grinding: Drastically reduces millbase viscosity, allowing for higher pigment-to-binder ratios and much shorter industrial milling times.
Eco-Friendly Profile: Formulated as a low-VOC, APEO-free additive, meeting stringent global environmental regulations and safety standards.
规格
技术亮点
Chemical Composition: High-molecular-weight polyurethane/polyacrylate block copolymer with multiple pigment-anchoring groups designed for robust and permanent adsorption.
Active Content: Typically supplied as a stable 40%–50% active solution in water or specialized water/glycol co-solvent mixtures.
Ionic Character: Non-ionic/Anionic hybrid nature, providing balanced stabilization through both sophisticated steric and basic electrostatic repulsion mechanisms.
Mechanism of Action: Steric stabilization prevents pigment agglomeration even under extreme high-shear processing or high-temperature storage conditions.
Viscosity Reduction: Achieves a Newtonian flow profile in millbases, facilitating easier handling, pumping, and filtration during production.
Pigment Versatility: Highly effective for fine carbon blacks, phthalocyanines, organic pigments, and standard titanium dioxide grades.
Solubility: Easily and quickly dispersible in aqueous media.
