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
Structural Innovation - Hyperbranched architecture enhances pigment wetting and prevents co-flocculation
Reactive Compatibility - Neutral pH avoids interference with epoxy/PU curing
Emission Control - Zero-VOC formulation meets AgBB sustainability criteria
Process Efficiency - Reduces grinding viscosity by 30-50% in high-load systems
Dual Stabilization - Combines steric hindrance and electrostatic repulsion for multi-pigment stability
Industrial Coatings - High-gloss finishes for machinery with TiO₂/extenders
Wood Coatings - Acid-cured furniture finishes requiring color consistency
Automotive OEM - Chip-resistant primers for metal substrates
Adhesives - Epoxy/PU formulations with CaCO₃/ATH fillers
Battery Cooling - Dielectric fluid stabilization (patented application)
