Dispersing agent DCA-8430

Introduction

DCA-8430 is a polymer type hyperdispersant containing multiple anchoring groups. It has excellent wetting and dispersing ability for various organic pigments, strong viscosity reducing ability, and is particularly suitable for grinding high pigment carbon black. It can greatly reduce the operating viscosity of the grinding system, increase the amount of pigment used, and when used in conjunction with pigment derivative viscosity reducing agents, the effect is even better. At the same time, it has a strong ability to prevent flocculation and coarsening, It can greatly improve the storage stability of the ground color paste, and the ground monochrome color paste is not easy to float during color mixing.
