BYK-2155 is a VOC-free, 100% active wetting and dispersing agent for solvent-free/solvent-borne coatings, floor paints, and printing inks. Its block-copolymer structure with pigment-affinic groups ensures steric stabilization of inorganic/organic pigments, enabling high pigment-load concentrates. Compatible with alkyds, epoxies, and PU systems, it optimizes viscosity reduction and flow properties
Specialized Stabilization - Optimized for carbon black and phthalocyanine pigments (blue/green)
Synergistic Performance - Works with BYK-SYNERGIST 2102 to boost color intensity and flow
Process Efficiency - Reduces mill base viscosity for higher pigment loading (up to 75% for carbon black)
Food Safety - Compliant with food contact regulations for printing inks
Polarity Adaptability - Effective in medium-to-non-polar solvent systems (e.g., nitrocellulose inks)
Printing Inks - Flexographic/gravure inks for packaging films, especially alcohol-soluble nitrocellulose types
Automotive Coatings - High-color-strength basecoats with carbon black dispersion
Pigment Concentrates - Solvent-free/solvent-borne high-load dispersions (organic pigments: 20-40%)
Industrial Coatings - Medium-polarity systems requiring stable phthalocyanine pigments
Food Packaging Inks - Compliant formulations for direct food contact applications
