DISPERBYK® 167 is a wetting and dispersing additive for solvent-borne coatings and pigment concentrates. It stabilizes pigments of all types and offers broad compatibility for all-purpose pigment concentrates based on aldehyde and acrylate grinding resins. It is the aromatic-free version of DISPERBYK® 163.

Chemical Family: Polyurethanes (PU)

Labeling Claims: Aromatic-free, Not Listed In California Proposition 65

Compatible Polymers & Resins: Acrylates

Features: High Color Strength, High Gloss, High Pigment Loading, Reduces Mill Base Viscosity

Special Note
  • 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.
Special Features and Benefits
  • 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.

Recommended Use
  • The additive is the aromatic-free version of DISPERBYK-163 and is used in many solvent-borne formulations.
  • It can also be used for retroactive batch correction.
  • For new formulations, we recommend checking the more modern additive DISPERBYK-2164.
Incorporation and 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.
