Toynol HD-2602 Wetting Dispersant for Resin-Free Color Paste
Toynol® HD-2602 Dispersing Agent
1 🎯 Abstract
Toynol® HD-2602 is a wetting and dispersing agent used in the preparation of resin-free slurry in water-based systems, specially designed for the grinding and dispersion of organic pigments in resin-free color pastes. It is composed of a solution of modified polystyrene maleic anhydride polymer and polyether ester surfactant. It can shorten grinding and dispersion time, reduce dispersion system viscosity, improve grinding dispersion efficiency significantly at lower dosage, and enhance grinding slurry stability. It also improves the color development of color pastes and is APEO-free, environmentally friendly.
