Introduction

7B-67 is mainly used for dispersion of inorganic pigment & filler and dumb powder, can shorten grinding time, improve production efficiency, and prevent the particles of pigment and filler secondary cohesion, enhance flocculation of resistance. For the Dispersing Agent can effectively change the rheological properties of slurry, it can fill a high volume of slurry, good liquidity, and reduce the amount of volatile organic compounds. Uniform particle size distribution, good transparency, can improve the low resin content slurry storage and transport stability.
