Product features and advantages

The additive is recommended for defoaming water-based printing ink and varnish; It can also be used for concentrated pigment slurry with good spontaneous defoaming effect. VOK?- DF 1719 has good effect even at low dosage, with low shrinkage tendency and high efficiency.

The additive does not contain VOC and ethylene glycol, and has a long shelf life.

Recommended dosage

0.1-0.5% of auxiliary dosage (supply form) is based on the general formula.

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

Adding method and processing guidance

The additive can be added at any stage of the production process. Due to its high activity, the defoamer needs to be added under high shear force to ensure good dispersion. Otherwise, it may cause system defects.
