Application Information

Coatings Industry
Special Features and Benefits

The synergist enables high-molecular weight wetting and dispersing additives to be more efficiently adsorbed on the surface of organic yellow, orange and red pigments, thereby increasing the effectiveness of the wetting and dispersing additives. Stabilization of the pigments is improved and higher pigment contents are possible as a result of a reduction in the viscosity.
Recommended Use
The synergist is always used in combination with high-molecular weight wetting and dispersing additives and is recommended for coatings and pigment concentrates.
Recommended Levels
Additive dosage as supplied based on pigment:
Organic yellow pigments (e.g. PY 154, PY 110): 2-4%
Organic orange pigments (e.g. PO 36, PO 62): 2-4%
Organic red pigments (e.g. PR 179, PR 254): 3-5%
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 powdered synergist must be incorporated in the millbase together with polymeric wetting and dispersing additives prior to adding the pigments.
