DISPERBYK® 2164 is a wetting and dispersing additive for solvent-borne coatings and pigment concentrates, offering a cost-effective alternative to DISPERBYK® 164 and DISPERBYK® 167. It is aromatic-free and enhances transparency, high color strength, and gloss. This additive reduces mill base viscosity and functions as both a wetting agent and dispersant. Ideal for coil coatings and pigment concentrates, DISPERBYK® 2164 ensures excellent performance in solventborne coatings, providing improved dispersion and stability in various industrial applications.

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.

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.
  • 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.
