Application Information

Coatings Industry
Special Features and Benefits

The additive deflocculates pigments through steric stabilization of the pigments. Due to the small particle size of the deflocculated pigments, high gloss is achieved and the color strength is improved. In addition, this product increases the transparency and hiding power of pigments and reduces viscosity. Subsequently, it improves leveling and allows for higher pigment loading.
Recommended Use
DISPERBYK-194 N is used for the production of pigment concentrates with or without resins and for pigment grinding in aqueous coatings. It is especially recommended for use with aqueous two-pack PU and two-pack epoxy systems. Pigment concentrates formulated with DISPERBYK-194 N can be incorporated into amine components as
well as epoxy resins.

Recommended Levels
Amount of additive (as supplied) based upon pigment
Inorganic pigments: 15-35%
Titanium dioxide: 7-13%
Organic pigments: 30-90%
Carbon black: 100-150%
The above recommended levels can be used for orientation. Optimal levels are determined through a series of laboratory tests.

Incorporation and Processing Instructions
For optimal performance in systems containing resins, the additive should be slowly incorporated into the aqueous resin while agitating the mixture. For pigment concentrates without resins, simply mix the additive with water. Add pigments only after the additive is homogeneously distributed.
Special Note
Pigment concentrates formulated with DISPERBYK-194 N must be neutralized before being added to let-down.
