BYK DISPERBYK-180 Wetting Dispersans Agents

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

Effect of BYK DISPERBYK-180 Wetting Dispersans Agents

  1. Dual Stabilization - Combines steric hindrance and electrostatic effects for uniform pigment dispersion

  2. Universal Compatibility - Works in waterborne, solvent-borne, and solvent-free formulations

  3. Process Efficiency - Reduces millbase viscosity by 30-50%, enabling higher pigment loading

  4. Optical Enhancement - Improves gloss, transparency (organic pigments), and hiding power (inorganics)

  5. Eco-Friendly - 100% active content, free of solvents and VOC (<1500 ppm)

Typical Applications of BYK DISPERBYK-180 Wetting Dispersans Agents

  1. Architectural Coatings - Exterior paints with stable TiO₂ dispersion

  2. Industrial Maintenance - Alkyd-based machinery finishes requiring anti-settling

  3. Printing Inks - Flexographic/gravure inks for food packaging (FDA compliant)

  4. Wood Coatings - Acid-cured systems needing improved color acceptance

  5. Pigment Concentrates - High-load dispersions (up to 10% for inorganics
