Application Information

Coatings and Printing Inks
Special Features and Benefits

The additive deflocculates pigments by steric stabilization. As a result of the small particle sizes of the deflocculated pigments, high levels of gloss can be achieved and the color strength is improved. Transparency and hiding power also increase and viscosity is reduced. In this way, leveling is also improved and higher pigment loading is possible.
Recommended Use
DISPERBYK® 108 is a solvent-free version of DISPERBYK-107. It is therefore especially suited for the manufacture of non-floating high-solids and aromatic-free architectural coatings. It may also be used in industrial coatings, leather coatings and printing inks (for gravure, flexographic and screen printing). DISPERBYK® 108 is also recommended for the manufacture of solvent-borne pigment concentrates in these areas.

Recommended Levels
Additive dosage as supplied based on pigment:
Inorganic pigments: 3-5%
Titanium dioxides: 0.8-1.5%
Organic pigments: 5-8%
Carbon blacks: 8-10%
The above recommended levels can be used for orientation. Optimal dosage levels are determined through a series of laboratory tests.
Incorporation and Processing Instructions
For optimum performance, the additive must be incorporated into the mill base prior to addition of pigments.
