Q1: What types of pigments and fillers is SOLSPERSE 32000 most effective with?
A: SOLSPERSE 32000 is specifically engineered for high-performance stabilization of organic pigments, carbon black, and inorganic oxides (e.g., titanium dioxide, iron oxides) in non-aqueous systems. It demonstrates strong affinity for polar pigment surfaces and delivers excellent wetting and long-term dispersion stability in demanding applications.
Q2: In which solvent- or resin-based systems is SOLSPERSE 32000 typically used?
A: This dispersant performs well in medium-to-high polarity media, including polyester, alkyd, acrylic, and polyurethane resins, as well as in aromatic and ketonic solvents. It is less suited for highly non-polar hydrocarbon systems without modification or co-additives.
Q3: How does SOLSPERSE 32000 contribute to improved millbase stability and final coating performance?
A: By providing steric stabilization and reducing interparticle attraction, SOLSPERSE 32000 helps maintain low viscosity during grinding, minimizes post-addition viscosity drift, and supports superior gloss, color strength, and resistance to settling or flocculation in finished coatings and inks.
Q4: What is the recommended addition method and timing for optimal performance?
A: For best results, SOLSPERSE 32000 should be added during the initial pigment wetting stage—typically before or concurrent with pigment incorporation into the vehicle. Pre-dilution in a compatible solvent or resin may improve uniform distribution, especially in high-viscosity systems.
Q5: Is SOLSPERSE 32000 suitable for use in low-VOC or high-solids formulations?
A: Yes—its efficient pigment stabilization allows formulators to reduce solvent demand and achieve higher solids content while maintaining grind stability and film quality. It supports formulation strategies aligned with modern environmental and performance targets.
