Proposed Dosages

Dosage based upon inorganic pigments, % Titanium dioxide
IR-210 5-10 2-4
The above-recommended dosages strongly depend on pigment particle size. Optimal dosages should be calculated in the laboratory according to a different formula.

Addition Methods&Process Technology Instructions

For optimum performance, these additives should be added to the abrasive before adding pigments.


These additives deflocculate pigments through steric hindrance because of the small particle sizes of the deflocculated pigments, High gloss is achieved and color strength is improved.

Additionally, transparency and hiding power are increased. These products can also reduce viscosity. Then flow leveling is improved, thus increasing the pigment content.


Applications IR-210
Industrial coatings Recommended
Architectural coatings Suitable
Coil coatings Recommended
Automotive coatings Recommended
Wood and furniture coatings Suitable
Protective coatings Recommended

Special Features

IR-210 IR-210 is suitable for stabilizing inorganic pigments (especially titanium dioxide) and strongly reduces the viscosity of abrasive. Because of its anionic character, it is ideal for acid-catalyzed systems (such as coil coatings). It can also reduce haze in inorganic pigmented coatings when electrostatic spraying.

Packing and Storage

Packed in iron drums of 25 or 200kg net each. The validity period is 12 months in sealed containers.

Special Notes

IR-210 Separation or turbidity may occur at temperatures below 5°C.
Because of its acidity, it may catalyze the crosslinking of baking systems.
Viscosity change of coating system should be checked during storage.
