BYK DISPERBYK-2118 is a solvent-free block copolymer Wetting Dispersans Agents for solvent-borne/solvent-free pigment concentrates and printing inks. Its pigment-affinic groups stabilize carbon black and phthalocyanine pigments (blue/green) via steric hindrance, particularly in medium-to-non-polar systems. Compatible with BYK-SYNERGIST 2102 for enhanced color strength and rheology control in flexographic/gravure inks
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
