Features and advantages: VOK ®- Disper 198 deflocculates pigments by means of space stabilization. As a result of the small particle size of the flocculated pigment, a high level of the glossiness can be achieved with the improved tinting power, transparency, and storage stability. Abrasive viscosity is high even if VOK ®- Low dose reduction of Disper 198. This makes it possible to produce a highly filled pigment concentrate with good flowability.

VOK ®- Disper 198, especially recommended for the production of water-based pigment concentrates, organic pigments and carbon black, is used in water-based printing inks and coatings.

Printing ink: 15% additive (if provided) based on organic pigment,

Carbon black coating: 50-100% additives (if provided) based on 100-200% additives (if provided) of organic pigments (if provided) based on carbon black addition method and processing guidance In order to obtain good performance, the additives should be slowly (stirring at the same time) added to the grinding resin, and the grinding resin solubilizer should be mixed or shear stable lotion. It is simply mixed with water in an adhesive free additive system. Only the pigment is added once the additive has been evenly distributed.
