Super Dispersant DCA-521

Introduction

DCA-521 is a high molecular weight dispersant with acidic groups, offering excellent wetting and anti-settling capabilities. It demonstrates outstanding thickening and dispersing abilities for inorganic pigments and metal powders, while significantly preventing coagulation and reagglomeration in well-grounded pigment pastes, thereby greatly enhancing storage stability.
