German technical background VOK ®- ATP wetting dispersant

VOK ®- Disper ATP wetting dispersant is applicable to solvent based and solvent-free coatings to improve pigment wettability, shorten grinding time and stabilize pigment dispersion. It can control the flocculation of stable pigments and fillers.

The additive is particularly suitable for self drying and baking paint systems to prevent pigment floating/blooming and settling. In batch production, it can also be added in the later stage of paint preparation.

In the oxidized base material, the additive can effectively inhibit the formation of skin.

When the amount of the additive is 0.1 - 0.2% of the total formulation, the scratch resistance and scratch resistance of the film can be improved.
