| Technical Data |
Solid Content: 40% & 45% Viscosity: <600cps |
| Main Application | Paint and Coatings: Essential in water-based paints to disperse pigments and fillers, improving texture, color consistency, and flow. They help in reducing volatile organic compounds (VOCs). Paper and Pulp: Used as anti-scaling agents and dispersants in paper manufacturing. Industrial Water Treatment: Act as effective inhibitors of mineral scale formation (e.g., calcium carbonate). Mineral Processing: Used to improve the efficiency of ultra-fine wet grinding for pigments and fillers like calcium carbonate. Detergents: Used to prevent dirt redeposition on clothes. Construction: Used in concrete formulations for better particle dispersion and performance. Oil Drilling: Used in drilling fluids for viscosity control. |
| Characteristics | Stabilization Mechanisms: Electrostatic Repulsion: Adsorb onto particles, giving them a negative charge that causes them to repel each other. Electrosteric Stabilization: Modern variants include side chains that provide additional steric hindrance, preventing particle collision even in complex or highly concentrated systems. Viscosity Reduction: Significantly lowers the viscosity of high-solid slurries (e.g., calcium carbonate), allowing for easier pumping and processing. Performance Enhancements: Improves color strength, gloss, and hiding power by ensuring pigments reach their primary particle size without agglomerating. Water Sensitivity: While essential for aqueous systems, they can increase the hydrophilicity of dried films, potentially leading to corrosion or adhesion issues if not properly formulated. Compatibility: Broadly compatible with inorganic pigments (like TiO₂), fillers, and various waterborne resins, though they may have limited wetting activity for difficult organic pigments |
