- DISPERBYK-2152 is based on hyperbranched technology, and was specially developed for use in solvent-free epoxy systems and other reactive systems as well as for two-pack polyurethane and acid-catalyzed systems.
- During grinding with pigments or fillers its polyester side chains are compressed, and the adhesion forces of the aminic groups toward the surface of the pigment or filler are increased. The pigment affinic group is then adsorbed onto the surface of the pigment or filler, while the polyester side chains still shield the aminic groups from the epoxy resin.
- This results in a strong reduction in viscosity and no reaction with the resin, allowing long-term storage stability.
- DISPERBYK-2152 features excellent pigment wetting and deflocculation.
- The additive is broadly compatible, with no negative effect on yellowing, adhesion of coatings to metals, or anti-corrosion properties.
Incorporation and Processing Instructions
For optimum performance, the additive must be incorporated into the millbase before addition of pigments.
This allows it to attain full effectiveness.
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.

- The additive is broadly compatible, with no negative effect on yellowing, adhesion of coatings to metals, or protective coating properties.
Incorporation and Processing Instructions
Wetting and dispersing additives should always be added to the millbase, which is the only way to attain full effectiveness.
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.
- Adhesives & Sealants
Recommended Levels
0.5-1.5% additive (as supplied) based upon fillers.
Special Features and Benefits
- The additive improves the wetting and dispersion of mineral fillers, such as calcium carbonate and aluminum trihydroxide (ATH).
- It is also suitable for aluminum powder and aluminum oxide.
- This lowers viscosity and allows higher filling levels.
Recommended Use
The additive is particularly recommended for adhesives on the basis of epoxy and polyurethane resins.Incorporation and Processing Instructions
For optimal performance, the additive should be incorporated before solids are added.
