The 6073 Zinc-Rich Primer Special Dispersant is a high-performance, non-ionic additive specifically engineered to address the complex stabilization challenges inherent in high-solids metallic coati…
Enhanced Wetting Efficiency: Rapidly displaces air and moisture from zinc powder surfaces, accelerating the grinding and dispersion process.
Superior Anti-Settling: Provides strong steric hindrance to prevent the formation of hard cakes, ensuring easy re-incorporation after storage.
Viscosity Reduction: Significantly lowers mill-base viscosity, allowing for higher pigment loading without compromising application properties.
Broad Compatibility: Exhibits excellent synergy with epoxy resins, polyurethanes, and various solvent-based systems commonly used in industrial coatings.
Improved Film Integrity: Enhances the uniformity of the zinc distribution, leading to denser films and improved long-term cathodic protection performance.
规格
技术亮点
Chemical Character: High molecular weight modified polycarboxylate/block copolymer solution, optimized specifically for metallic pigment stabilization.
Active Content: Typically maintained at 50% ± 2%, providing a concentrated solution for efficient dosage control in formulations.
Ionic Nature: Non-ionic/Anionic characteristics allow for stability across a wide range of solvent polarities and resin acid values.
Solvent System: Usually supplied in a blend of aromatic hydrocarbons (e.g., Xylene/PMA) to ensure seamless integration into solvent-borne primers.
Performance Stability: Maintains effectiveness across extreme temperature fluctuations, preventing flocculation during high-shear mixing or thermal aging cycles.
