Properties and Applications

AGITAN 731 is a highly effective siloxane defoamer for aqueous emulsion and water reducible systems. It is particularly effective in aqueous printing inks. A non-ionic structure provides excellent compatibility with most common binders.

Main applications:

  • Architectural coatings
  • Liquid building products
  • Industrial and wood coatings
  • Printing inks
  • Adhesives
  • Cleaners
  • High-temperature process water
  • Vacuum destillation
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 731 has to be added in the early stage of the manufacturing process. This will ensure uniform distribution with a minimal amount of AGITAN 731. 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 731 in almost every co-solvent may improve dispersion of the defoamer. The recommended dosage for process water treatment is 50-200 pp
