​BYK-2152 Wetting Dispersing Agents

BYK-2152 is a hyperbranched polyester Wetting Dispersing Agents engineered for solvent-free epoxy and reactive systems (e.g., 2K PU, acid-cured). Its unique structure combines steric stabilization with amine-group shielding to prevent resin interference, ensuring viscosity reduction and long-term pigment stability while complying with German AgBB standards for low emissions

Effect of BYK-2152 Wetting Dispersing Agents

  1. Structural Innovation - Hyperbranched architecture enhances pigment wetting and prevents co-flocculation

  2. Reactive Compatibility - Neutral pH avoids interference with epoxy/PU curing

  3. Emission Control - Zero-VOC formulation meets AgBB sustainability criteria

  4. Process Efficiency - Reduces grinding viscosity by 30-50% in high-load systems

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

Typical Applications of BYK-2152 Wetting Dispersing Agents

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

  2. Wood Coatings - Acid-cured furniture finishes requiring color consistency

  3. Automotive OEM - Chip-resistant primers for metal substrates

  4. Adhesives - Epoxy/PU formulations with CaCO₃/ATH fillers

  5. Battery Cooling - Dielectric fluid stabilization (patented application)
