BYK DISPERBYK-118 is a high-polarity copolymer Wetting Dispersans Agents designed for solvent-based coatings and inks. It uniquely stabilizes all titanium dioxide variants (acidic/neutral/alkaline-treated) while enhancing inorganic pigments, fillers, and effect pigments. The linear polymer structure with pigment-affinic groups ensures viscosity reduction and long-term stability without compromising metal adhesion
Universal TiO₂ Stabilization - First dispersant to effectively stabilize all surface-treated titanium dioxide types
Multi-Pigment Compatibility - Works with inorganic pigments, transparent iron oxides, and effect pigments
Process Enhancement - Reduces grinding viscosity by 40-60% for higher pigment loading
Optical Improvement - Increases gloss while minimizing haze in final coatings
Adhesion Preservation - Maintains metal substrate bonding strength in direct-contact coatings
Industrial Coatings - High-gloss machinery finishes with TiO₂/extenders
Automotive Refinish - Metallic basecoats requiring color consistency
Wood & Furniture Coatings - Nitrocellulose lacquers with improved flow
Pigment Concentrates - High-load dispersions (up to 90% carbon black)
Architectural Coatings - Exterior paints with enhanced weather resistance
