Product features and advantages

The defoaming agent was specially developed for various emulsion systems without APEO. Due to the addition of silicone, the additive has better defoaming effect. VOK®-DF 038 is recommended for emulsion systems with pigment volume concentrations ranging from 20 to 70.

Recommended use

It is especially recommended for latex paint, high gloss emulsion system and emulsion plaster. The defoaming agent can also be used in the production of emulsion adhesives.

Suggested usage

0.1-0.5 % additive amount (purchase form) based on the total formula. Up to 0.8 % under certain circumstances.

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

Adding method and processing instruction

Under normal circumstances, 2/3 of the amount of the defoaming agent can be added to the abrasive and 1/3 of the amount can be added to the mixing or finished paint. In order to avoid defects, it must be added with sufficient shear force.
