BYK-2164 Wetting Dispersing Agents

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

Effect of BYK-2164 Wetting Dispersing Agents

  1. Dual Stabilization - Combines steric hindrance and electrostatic repulsion for pigment stability

  2. Economic Efficiency - 30% cost reduction vs. DISPERBYK-164/167 without performance compromise

  3. Process Optimization - Reduces grinding viscosity by 40-50% for faster dispersion

  4. Broad Compatibility - Works with inorganic/organic pigments including carbon black

  5. Emission Control - Aromatic-free solvent blend (butyl acetate/PMAc) meets VOC regulations

Typical Applications of BYK-2164 Wetting Dispersing Agents

  1. Automotive OEM - Color-stable basecoats for metallic finishes

  2. Industrial Coatings - High-gloss machinery finishes with TiO₂/extenders

  3. Packaging Inks - Flexographic inks for film printing

  4. Wood Coatings - Acid-cured systems with improved transparency

  5. Pigment Concentrates - High-load dispersions (up to 70% carbon black)
