German technical background VOK-052 N Defoamer Applicable to solvent-based and solvent-free systems replaces BYK-052 N

VOK?-DF 052 N is suitable for use as a non-silicone defoamer in solvent-based and solvent-free systems and is used as a standard defoamer in many solvent-based coatings.

Typical physicochemical data

The data given in this data page are only typical values, not technical indicators of the product.

Density (20 °C): 0.81 g/ml

Nonvolatile (10 min, 150 °C): 20%

Solvent: solvent gasoline

Flash point: 43 °C

Application field

Coating industry

Features and Advantages

VOK?-DF 052 N is less compatible than VOK?-DF 051 N, so it is used as a standard defoamer in many solvent-based paints. It has a stronger defoaming effect than VOK?-DF 051 N, especially in non-polar systems. Due to its reduced compatibility compared to VOK?-DF 051 N, its effect on varnish clarity and shrinkage must be evaluated.

It is recommended to use

Industrial coatings

Automobile original paint

Paint for wood and furniture

Architectural coatings

Anticorrosive coatings

The recommended dosage of 0.05-0.5% additives (supply form) is based on the total formula.

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

Adding method and processing instruction

For good performance, the defoaming agent should be added to the abrasive before grinding. If added at a later stage, sufficient shear force is required to ensure a good dispersion of the defoaming agent to prevent shrinkage.

Printing ink and gloss oil

Features and Advantages

VOK?-DF 052 N prevents the formation of foam in printing inks during manufacturing and construction. The agent has a rapid defoaming effect and does not affect the interlayer adhesion.

Application field

Solvent-based and solvent-free printing inks and glossy oils
