Key Benefits

This product is soluble in water, acid, alkali, salt and hard water, has good diffusion performance. Dispersing agent for use in waterborne coatings is necessary to water soluble, which are selected to be adsorbed on the surface of the powder and water. This product is anion type, which are ionized in water to form anions, has a surface active, adsorbed powder surface. The powder particle in surface adsorpted dispersant is formed double electric layer


Mainly used in disperse dyes, vat dyes, reactive dyes, acid dyes and dyes in the leather as a dispersant. dye of milling efficiency、solubilization、dispersibility are excellent. Can also be used for textile dyeing, wettable pesticide,paper making,electroplating additive,pigment, carbon black, water soluble paint in latex、rubber、building, water treatment agent in oil drilling.
