Application field

Printing ink

Product features and advantages

VOK ®- DF 017 is particularly suitable for defoaming in the dispersion of abrasive and subsequent processing. The additive has good defoaming performance during grinding and good storage stability. Therefore, the product can improve the grinding and treatment process of finished pigment concentrate slurry.

Recommended use

The additive is especially recommended for water-based pigment concentrate of printing ink system. The recommended dosage is 0.2-0.8% of the auxiliary dosage (purchase form) based on the general formula.

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

Due to the high incompatibility of additives, the defoamer must be added under high shear force to ensure good dispersion. Otherwise, it may cause system defects.
