Indofil 850 | High-Efficiency Low-Foaming Pigment Dispersant
Indofil 850 is a premium, very low-foaming liquid dispersant specifically engineered for the wetting and stabilization of inorganic pigments and extenders. By adsorbing onto particle surfaces, it prevents agglomeration during the pigment grinding process, maximizing coating performance properties such as opacity, tinting strength, and gloss. Optimized for systems with a pH of 9.0 to 10.0, this advanced additive reduces mill viscosity to allow for higher pigment loading, eliminates pigment floating and settling, and provides exceptional stability in formulations containing reactive pigments like zinc oxide.
Product Overview
Indofil 850 is a highly efficient, industrial-grade liquid dispersing agent designed to optimize the pigment grinding and de-agglomeration stage of paint manufacturing. Produced by an ISO 9001 and 14001 certified company, this specialized additive functions by adsorbing directly onto the surfaces of inorganic pigments and extenders. The resulting steric hindrance prevents particles from re-associating, ensuring excellent wetting, uniform stabilization, and enhanced fluid dynamics within the grind base.
Soluble exclusively in polar solvents like water, glycerin, and ethylene glycol, Indofil 850 is an essential tool for paint formulators seeking to achieve maximum color development, high gloss, and consistent batch stability.
Enhanced Optical Properties: By ensuring a perfectly uniform particle dispersion, it significantly elevates the final paint's hiding power (opacity), tinting strength, and specular gloss.
Reduced Mill Viscosity: Lowers the viscosity during the grinding phase, allowing formulators to increase pigment and extender loading capacities for highly cost-efficient production.
Anti-Settling & Anti-Floating Control: Actively works to overcome pigment floating, flooding, and hard settling over time, extending the container shelf life of finished paints.
Excellent Reactive Pigment Stability: Delivers superior performance and viscosity stability in complex systems where reactive pigments—such as zinc oxide or basic lead silicate—are incorporated.
Improved Flow & Leveling: Contributes to excellent application properties, allowing the finished paint to level smoothly out of the brush or roller without tracking marks.
Compatible Systems: Widely utilized in commercial trade sales paints formulated with Acrylic, Butadiene-Styrene, and Polyvinyl Acetate (PVA) emulsion systems.
Pigment Compatibility: High-efficiency performance across a massive range of inorganic pigments and mineral extenders.
Recommended Dosage: 0.4% – 1.0% Indofil 850 based strictly on the total dry weight of the pigments/extenders. For maximum chemical effectiveness, it should be used in systems adjusted to a pH of 9.0 to 10.0.
