Recommended Levels and Use

Normal dosage ranges from 0.05 to 0.2 % on finished product. Ladder studies are recommended to determine optimum level. For aqueous printing inks AGITAN 760 has to be added in the early stage of the manufacturing process. This will ensure uniform distribution with a minimal amount of AGITAN 760. Optimum dispersion in low viscosity systems is possible if high levels of wetting agents are present or high shear is applied which assists the incorporation of the defoamer. Dilution of AGITAN 760 in almost every co-solvent may improve dispersion of the defoamer.
