- Product Function
- These high molecular weight additives deflocculate pigments through steric stabilization of the pigments.
- They provide equal electrical charge to pigments and thus avoid additionally possible co-flocculation of pigments that are not equally charged.
- Due to the small particle sizes of the deflocculated pigments, high gloss is achieved and color strength improved.
- Additionally, transparency of transparent pigments and hiding power of opaque pigments are increased.
- These products reduce viscosity, subsequently, leveling is improved and higher pigment loading is possible.
- Application Information
Coatings Industry
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. In addition, the additive increases transparency with transparent pigments and hiding power with opaque pigments. Viscosity is reduced. In this way,
the leveling properties are also improved and higher pigment loading is possible.
Recommended Use
DISPERBYK® 145 is highly compatible with all standard coating binders. DISPERBYK® 145 is particularly recommended for non-polar systems (alkyd and acrylate resins, TPA and epoxy resins).Recommended Levels
Amount of additive (as supplied) based upon pigment:
Inorganic pigments: 5-10%
Titanium dioxide: 1-3%
Organic pigments: 10-25%
Carbon black: 15-35%
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 mill base before the addition of pigments.

- Special Note
- In baking enamels, DISPERBYK® 145 may have a negative influence on adhesion on steel substrates.
- Before using in white baking enamels, DISPERBYK® 145 should be checked for possible yellowing.
