Indofil HSD 45 | High-Solid Polycarboxylate Dispersing Agent
Indofil HSD 45 is a highly effective, low-viscosity polymeric dispersing agent designed to optimize water-borne coating systems. Formulated as a high-solid sodium salt of polycarboxylate ($44-46\%$ solids), it delivers exceptional electrostatic stabilization to prevent pigment re-agglomeration, significantly reducing grinding time and formulator dosage. Extremely versatile across Low, Medium, and High PVC paint formulations, this advanced dispersant enhances viscosity stability, lowers defoamer requirements, and minimizes transportation costs—offering a powerful competitive and economical advantage.
Product Overview
Indofil HSD 45 represents the latest advancement in low-molecular-weight polymeric dispersing agents engineered for the modern paint and coatings industry. Manufactured by an ISO 9001 and 14001 certified company, this high-solid sodium salt of polycarboxylate is specifically optimized for water-based systems. It functions by rapidly wetting inorganic pigment surfaces and adsorbing onto freshly milled particles to create a robust electrostatic stabilizing layer. This energy barrier neutralizes Van der Waals forces, completely preventing re-agglomeration.
With its high active solids content ($44-46\%$), Indofil HSD 45 allows formulators to use lower dosages while drastically minimizing water transportation costs, providing a substantial economic edge without compromising paint performance.
High-Solid Cost Efficiency: The highly concentrated $45\%$ active solid composition requires exceptionally low addition levels, cutting raw material consumption and optimizing formulation costs.
Electrostatic Particle Stabilization: Provides a powerful energy barrier around mineral pigments and extenders, ensuring exceptional, long-term viscosity stability in the finished paint.
Optimized Production Dynamics: Accelerates the mechanical milling and dispersion process, which drastically reduces required grinding times and lowers overall energy consumption.
Reduced Defoamer Demand: Formulated to improve system compatibility, effectively reducing the overall defoamer requirements during the grinding stage.
Broad PVC Versatility: Functions with high efficiency across the entire spectrum of architectural coatings, making it ideal for High, Medium, and Low PVC (Pigment Volume Concentration) paint designs.
Ready-to-Use Liquid Handling: Delivered as a low-viscosity liquid that is easy to pump, pour, and seamlessly blend into automated or manual batching processes.
Compatible Coatings: Water-borne architectural paints, industrial coatings, and mineral-filled systems.
Pigment Specialization: Highly recommended for the rapid wetting and stable dispersion of inorganic pigments and mineral extenders.
Recommended Dosage: 0.4% – 1.0% Indofil HSD 45 based strictly on the total dry weight of the pigments/extenders.
