Toynol® DS-260 Dispersant
1 🎯 Abstract
Toynol® DS-260 is a wetting and dispersing agent for water-based systems, printing inks, and adhesives. Its chemical composition is a solution of amine alkyl hydroxyl adduct of polystyrene maleic anhydride polymer. It is APEO-free, capable of reducing grinding system viscosity, improving color paste color development and dispersion stability, and is especially suitable for high-concentration carbon black color paste preparation. Compatible with titanium dioxide, carbon black, organic red and other pigments.
