Indofil 731 TL | Versatile Acrylic Polyelectrolyte Dispersing Agent
Indofil 731 TL is a highly versatile, water-borne acrylic dispersing agent designed to optimize particle stabilization across a vast range of latex-based coatings. Formulated as a sodium salt of a carboxylate polyelectrolyte, it effectively prevents the re-association of pigments and extenders to control mill viscosity, eliminate pigment floating, and prevent settling. Exhibiting excellent thermal stability and universal compatibility, it seamlessly enhances flow, leveling, and gloss development in everything from low-VOC formulations to high-gloss architectural topcoats.
Product Overview
Indofil 731 TL is a universally compatible, industrial-grade acrylic dispersing agent engineered to deliver exceptional wetting and stabilization in water-borne paint systems. Operating as a sodium salt of a carboxylate polyelectrolyte, this pale yellow liquid provides powerful electrostatic stabilization by adsorbing onto particle surfaces. By establishing a robust energy barrier, it prevents the natural re-association of pigment and extender particles during and after the mechanical milling process.
Indofil 731 TL stands out as a highly versatile additive, delivering predictable dispersion, excellent container stability, and pristine final film properties across a comprehensive array of architectural paint formulations—ranging from ultra-flat mattes to premium high-gloss topcoats.
Universal System Compatibility: Integrates effortlessly with a vast range of inorganic pigments, mineral extenders, and diverse latex emulsion polymer backbones.
Optimized Flow & Leveling: Significantly improves the rheological profile of the finished coating, facilitating superior flow, uniform leveling, and enhanced specular gloss upon application.
Anti-Settling & Anti-Floating Control: Actively mitigates the risks of pigment flooding, floating, and hard caking inside the container, ensuring uniform color consistency over time.
Mill Viscosity Reduction: Lowers grinding-phase viscosity, enabling paint formulators to significantly increase pigment and extender loading for better manufacturing throughput.
Excellent Thermal Stability: Demonstrates high resistance to heat degradation, protecting the formulation's structural stability during intensive grinding cycles and long-term storage.
Broad Coating Spectrum: Low-VOC paints, interior/exterior mattes, sheens, semi-gloss finishes, and high-gloss architectural topcoats.
pH Target Range: Engineered to deliver its highest chemical efficiency within a formulation pH range of 9.0 to 9.5.
Recommended Dosage: 0.4% – 1.0% Indofil 731 TL based strictly on the total dry weight of the pigments and extenders.
