- Key Features
- DISPERBYK® 2022 deflocculates pigments and stabilizes them by means of steric hindrance.
- It prevents a possible coflocculation, which leads to non-floating coloring in pigment blends.
- The deflocculation of the pigments results in increased gloss, color strength, transparency or hiding power, and a reduced millbase viscosity.
- The additive is urethane-free and has a broad compatibility with a focus on low-polarity and medium-polarity systems.
- If the coatings are applied directly to metal, the adhesion is outstanding and a positive influence on salt-spray resistance has been observed.

- Processing Instructions
- Wetting and dispersing additives should generally be added to the millbase.
- Only in this way can they be fully effective.
- In the case of binder-free grinds, the solvent components of the millbase are pre-mixed with the additive whilst stirring, before the pigment is added.
- If the grinds contain binder, the binder, solvent, and additive should be homogenized prior to adding the pigment.
- Recommended Uses
- Pigment grinding with DISPERBYK® 2022 can take place either with or without binder.
- The additive is suitable for single grinds and co-grinds.

- Deflocculated pigments have a greater tendency to settle.
- This particularly applies to inorganic pigments which have a greater density. The use of liquid rheology additives, such as BYK-410 or BYK-430, in the grinding phase counters this phenomenon.
