Application field

Paint, printing ink, adhesive and PVC plastisol

Product features and advantages

VOK ®- Disper 9077 enables pigment to deflocculate through steric stabilization. At the same time, it can also make pigment particles have the same charge, and the generated repulsive force and steric hindrance stability prevent the occurrence of flocculation, so as to obtain the color appearance without blooming in the system containing multiple pigments. Because the particle size of the deflocculating pigment is small, it can obtain high luster and improve the dyeing force. In addition, the transparency of transparent pigments and the hiding power of opaque pigments can also be improved. Due to its viscosity reducing effect, the flowability is improved, and the addition amount of pigment can be increased.

Recommended use

VOK ®- Disper 9077 is suitable for all kinds of pigments, especially for stable alkaline carbon black pigments. It can be used for solvent based and solvent-free coatings, adhesives, PVC plastisols and solvent-free UV printing inks. An important application field of the invention is to prepare solvent free pigment concentrate slurry for the above applications.

Recommended dosage

The amount of additives (purchased form) is based on the following pigments:

Inorganic pigment: 5-10%

Titanium dioxide: 1-3%

Organic pigment: 10-25%

Carbon black: 15-50%

The above recommended dosage is for reference only, and the appropriate dosage shall be determined through a series of tests.

Adding method and processing guidance

In order to obtain good performance, the additive must be added to the abrasive before the pigment is added.
