BYK-2155 Wetting Dispersans Agents

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

Effect of BYK DISPERBYK-2118 Wetting Dispersans Agents

  1. Specialized Stabilization - Optimized for carbon black and phthalocyanine pigments (blue/green)

  2. Synergistic Performance - Works with BYK-SYNERGIST 2102 to boost color intensity and flow

  3. Process Efficiency - Reduces mill base viscosity for higher pigment loading (up to 75% for carbon black)

  4. Food Safety - Compliant with food contact regulations for printing inks

  5. Polarity Adaptability - Effective in medium-to-non-polar solvent systems (e.g., nitrocellulose inks)

Typical Applications of BYK DISPERBYK-2118 Wetting Dispersans Agents

  1. Printing Inks - Flexographic/gravure inks for packaging films, especially alcohol-soluble nitrocellulose types

  2. Automotive Coatings - High-color-strength basecoats with carbon black dispersion

  3. Pigment Concentrates - Solvent-free/solvent-borne high-load dispersions (organic pigments: 20-40%)

  4. Industrial Coatings - Medium-polarity systems requiring stable phthalocyanine pigments

  5. Food Packaging Inks - Compliant formulations for direct food contact applications
