Applications

Special Features and Benefits:

Particularly suitable for the dispersion of organic pigments in water-based coatings, it has a wide compatibility with many water-based resin systems and stabilizes the dispersion performance of pigments.

Recommended Use:

HH2991 water-based wetting dispersant has a wide range of compatibility with different water-based resins and pigments.

Used for water-based general color paste, coating, water-based ink, nano color paste, pesticide dispersion grinding, wet grinding of various inorganic powders.

• Addition amount

Organic pigment 30~40%

Inorganic powder 5~10%

Carbon black 30~50%

*. The above data are the dosage ratios in the formula. The optimal dosage needs to be determined through a series of tests.

• Instructions for use

When it is below 10℃ (50°F), due to its large molecular weight, the viscosity will increase. Heating is required to reduce the viscosity.

Mix HH2991 dispersant with the liquid in the formula, then add the powder and stir and disperse it evenly before grinding.

*、Please do a step test for the specific dosage to ensure the best and appropriate dosage.
