BYK-2164 is a modified polyurethane Wetting Dispersing Agents designed for solvent-based coatings and pigment concentrates. As an economical alternative to DISPERBYK-164/167, it stabilizes pigments via steric hindrance and charge equalization, preventing co-flocculation in multi-pigment systems. Its high solid content (60%) and aromatic-free formulation enhance compatibility with industrial applications
Dual Stabilization - Combines steric hindrance and electrostatic repulsion for pigment stability
Economic Efficiency - 30% cost reduction vs. DISPERBYK-164/167 without performance compromise
Process Optimization - Reduces grinding viscosity by 40-50% for faster dispersion
Broad Compatibility - Works with inorganic/organic pigments including carbon black
Emission Control - Aromatic-free solvent blend (butyl acetate/PMAc) meets VOC regulations
Automotive OEM - Color-stable basecoats for metallic finishes
Industrial Coatings - High-gloss machinery finishes with TiO₂/extenders
Packaging Inks - Flexographic inks for film printing
Wood Coatings - Acid-cured systems with improved transparency
Pigment Concentrates - High-load dispersions (up to 70% carbon black)
