Recommended

Industrial coatings

Architectural coatings

Wood and furniture coatings

Coil coating

Anticorrosive coating

Recommended dosage

0.1-1.5% additives (supply form) are based on the general formula.

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

Adding method and processing guidance

In order to obtain good performance, defoamer should be added to the abrasive before grinding. If it is added in the later stage, there must be enough shear force to ensure good dispersion of defoamer and prevent shrinkage cavity.

Printing ink and varnish

Features and advantages

VOK ®- DF 057 can prevent the formation of foam during the manufacturing and construction of printing ink. The additive has rapid foam breaking effect and does not affect the adhesion between layers.

Application field

Especially recommended for solvent-free radiation curing printing ink and varnish.
