Water Based Wetting Dispersant LD-64190

(Similar to BYK-190)

First, 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.

 

Second,Typical physicochemical data

Composition: high molecular weight block copolymer solution

Appearance: brown transparent liquid

Solvent: water

Flash point (℃): > 100

Acid value: 10 mgKOH / g

Solid content: 40%

 

Third, Recommended dosage

Inorganic pigment: 20% - 30%

Titanium dioxide: 10% - 12%

Organic pigment: 30% - 75%

Carbon black: 130% - 150%

 

Fourth, adding method and processing instruction

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.

 

Fifth,application area

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

 

Sixth,Features and benefits

Ld-64190 is 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, ld-64190 and water (without resin and cosolvent) are recommended for grinding to obtain properties. Ld-64190 does not contain organic solvents and is only suitable for aqueous systems.
