LD-64190 & LD-64192 Water Based Wetting Dispersant

1.  Summary

LD-64190 flocculates the pigment by steric hindrance. Due to the small size of the flocculated pigment particles the luster and color intensity are improved. In addition, increase the transparency and covering power of products. As the viscosity of the product decreases after dispersion, the leveling property is improved and the pigment content is increased

LD-64192 enables pigment to deflocoulate through space steric hindrance. Because the pigment particles of deflocculation are very small, the luster and color intensity are improved. in addition. increase product transparency and hiding power.As the viscosity of the product is reduced after dispersion, the leveling property is improved, and the content of pigment can be increased.

2.  Typical Physicochemical Data

3. Addition method and processing guidance

For performance, auxiliaries should be added slowly (stirring) to the mixture of grinding resin, cosolvent or emulsion resin. When it is used in resin free pigment concentrate, before adding pigment, the additive and water should be mixed evenly, and the pigment should be added after the additive is fully dispersed.

4. Application area

Recommended: water based pigment concentrate, architectural coatings, industrial coatings, automotive coatings, wood and furniture coatings, anti-corrosive coatings, printing ink.

5. Features and benefits

LD-64190 & LD-64192 are the best dispersant for producing stable pigment concentrated slurry without resin for general industrial water-based coating system without floating color and blooming. Only pigment,  them and water (without resin and co-solvent) are recommended for grinding to obtain properties. They do not contain organic solvents and are only suitable for aqueous systems.
