DISPERBYK® 102

Coatings Industry
Special Features and Benefits
The additive deflocculates pigments through steric stabilization of the pigments. DISPERBYK-102 is primarily recommended for universal colorants based on DISPERBYK-185. It reduces viscosity and increases color strength. It can be used in solvent-borne and aqueous systems as a post-additive to improve color strength and color acceptance.

Recommended Levels
Amount of additive (as supplied) based upon pigment:
Inorganic pigments: 5-10%
Titanium dioxide: 1-3%
As a post-additive to improve color acceptance: 0.5-2% additive (as supplied) based upon total formulation. The above recommended levels can be used for orientation. Optimal levels are determined through a series of laboratory tests.
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. To improve color acceptance, the additive can also be post-added into the coating.

The drying of alkyd resins can be affected if overdosed.
