Features and benefits 

VOK®-FL 352 is an additive that combines crater resistance with leveling properties. It can enhance the gloss of the coating and improve the long-wave leveling effect; Slightly reduces surface tension without affecting recoating and interlaminar adhesion. The additive also has a deaeration function and good thermal stability. 

Recommended Use 

The additive is recommended for solventborne and solvent-free coating systems. 

Recommended dosage 

0.2-0.5% Additive dosage (form of supply) is based on the total formulation and can be increased to 1% in exceptional cases. 

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

Addition method and processing guidance 

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