Features and benefits 

VOK-392 is used as an explosion-proof foam additive in solvent-based baking paint systems. At the same time, its non-polar structure makes it also have defoaming and deaeration effects. This additive is particularly suitable for airless/air spray systems, slightly reducing surface tension and improving gloss and leveling of coatings. 

Recommended Use 

Solvent-based paint system. 

Recommended dosage 

0.1-1% additive dosage (form of supply) is based on total formulation. 

The above recommended dosage is for reference only, and the appropriate dosage needs to be determined after a series of tests. 

Addition method and processing guidance 

The additive can be added at any stage of production, including post-adding.
