- Key Features
- The additive deflocculates pigments and stabilizes them by means of steric hindrance.
- It provides equal electrical charge to the pigment particles.
- The resulting repulsion and the steric stabilization prevent a possible co-flocculation, which leads to flood and float-free color in pigment mixtures.
- The deflocculating properties of the additive increase gloss, color strength, transparency, and hiding power and reduce the viscosity of the millbase.

- Processing Instructions
- For optimum performance, the additive must be incorporated into the millbase before addition of pigments.
- The resin and solvent components of the millbase are pre-mixed and then the additive is slowly incorporated while stirring continuously.
- Do not add the pigments until the additive has been fully distributed.
- Post-addition (to repair faulty batches) is possible as long as the product is added slowly and under high shear forces.
- Recommended Uses
- This additive should be given priority in new formulations due to having a higher solids content and being aromatic-free.
- It is an alternative to DISPERBYK-164 and DISPERBYK-167 for solvent-borne pigment concentrates and coatings.

- The after-treatment of some organic pigments may negatively affect the efficiency of the additive.
- In such cases, tests with the untreated pigment of the same type may be successful.
- When used in coil coatings, the interaction of this cationic additive with the acid catalyst must be taken into account.
- Amine-blocked acids are less suitable than free acids or epoxy-blocked acids.
- This problem can be avoided by using additives from the DISPERBYK-170 product line.
- Deflocculated pigments have a higher tendency to settle.
- This is particularly true for inorganic pigments with a high density. Using liquid rheological additives such as BYK-410 or BYK-430 during grinding prevents this problem.
