Product features and advantages

VOK ®- DF 094 is especially recommended for defoaming of water-based flexographic printing ink, gravure printing ink and varnish. The defoamer has good spontaneous defoaming effect and excellent stability on the printing press. Inhibit foaming in the ink pipeline or pump system.

Recommended dosage

0.2-1% auxiliary dosage (purchase 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 is added in the paint mixing process, however, the additive can be added at any time of production. Due to the high activity of the defoamer, it must be added under a moderate shear force to ensure good dispersion. Otherwise, the system may have defects.

an adhesive

Product features and advantages VOK ®- DF 094 is recommended for defoaming of various common water-based adhesive systems.

Recommended dosage

0.05-1% auxiliary dosage (purchased form) is based on the total 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 time of production.

Coating industry

Product features and advantages VOK ®- DF 094 is especially recommended for water-based paints and varnish coatings. The antifoaming agent can inhibit the foaming of coatings in production and construction, and has good long-term stability.

Recommended dosage

0.1-1% auxiliary dosage (purchase 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 time of production. Defoamer is usually added in two steps (2/3 of the amount is added to the abrasive, and 1/3 of the amount is added to the paint mixing process or finished paint).
