DISPERBYK-102  

Solvent-free wetting and dispersing additive for polar to medium polar coatings in solvent-borne and water-borne systems to improve the acceptance of colorants of inorganic pigments in base paints.

Copolymers containing acidic groups

  Typical materialized data

 storage and transportation  

At temperatures below 10 °C, layering or turbidity may occur, warm to 30-60 °C and mix well before use.

  special reminder

Excessive addition may affect the drying properties of the alkyd resin.

  paint industry  

Features and Benefits: The additive deflocculates pigments through steric stabilization. DISPERBYK-102 is primarily recommended for general purpose colorants prepared using DISPERBYK-185. It reduces viscosity and increases tinting strength. It can be used as a post-additive in solvent-borne and water-borne systems to improve tinting strength and colorant acceptance.

Recommended dosage 

Auxiliary dosages (as purchased) are based on pigments.

When post-added to improve colorant acceptance: 0.5-2% adjuvant (as purchased) based on total formulation.
The above recommended dosage is for reference, and the optimum dosage needs to be determined through a series of tests.
  Joining method and processing guidance 

For optimum performance, additives must be added to the millbase before the pigment. The resin and solvent components in the millbase are pre-mixed, and then the additives are slowly added under continuous stirring. Do not add pigments when the additives are not completely dispersed. The additive can also be post-added to the paint in order to improve colorant acceptance.
