BYK DISPERBYK-180 is a solvent-free alkylol ammonium salt copolymer Wetting Dispersans Agents for aqueous, solvent-borne, and solvent-free systems. It stabilizes inorganic pigments (especially TiO₂) via steric hindrance and charge equalization, preventing co-flocculation. Compatible with coatings, inks, and adhesives, it enhances processability in resin-free/resin-containing grinding systems while maintaining low-VOC compliance
Dual Stabilization - Combines steric hindrance and electrostatic effects for uniform pigment dispersion
Universal Compatibility - Works in waterborne, solvent-borne, and solvent-free formulations
Process Efficiency - Reduces millbase viscosity by 30-50%, enabling higher pigment loading
Optical Enhancement - Improves gloss, transparency (organic pigments), and hiding power (inorganics)
Eco-Friendly - 100% active content, free of solvents and VOC (<1500 ppm)
Architectural Coatings - Exterior paints with stable TiO₂ dispersion
Industrial Maintenance - Alkyd-based machinery finishes requiring anti-settling
Printing Inks - Flexographic/gravure inks for food packaging (FDA compliant)
Wood Coatings - Acid-cured systems needing improved color acceptance
Pigment Concentrates - High-load dispersions (up to 10% for inorganics
