Coating industry

Product features and advantages

VOK ®- DF 085 is a silicone defoamer, which can inhibit the formation of foam and bubbles in the production and processing of non-polar and even highly polar solvent based and solvent-free coatings. When recoating, the additive will not cause difficulty in re wetting or affect the adhesion between layers. As the additive is supplied in solvent-free form, it is specially used for solvent-free systems or systems where intermediates require special solvents.

Recommended dosage

0.01-0.4% auxiliary dosage (purchase 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 stage of the production process.
