Scope of application

  • Coalescent in latex-based aqueous coatings; Used as a solvent in domestic and industrial cleaners, lubricants and paints
  • It is a good solvent for aqueous and non-aqueous paint and varnish coatings;
  • It is used as a chemical intermediate for the production of epoxies, acid esters, solvents and plasticizers.


  • Effectively lowers the minimum film formation temperature in aqueous latex-based coatings, even in small quantities;
  • Evaporation rate is low;
  • Contributes to the formation of high quality latex film;
  • It migrates to the polymer phase to a high degree;
  • Effectively reduces surface tension;
  • Effectively cleans surfaces from dirt;
  • It is a good solvent for oils and fats;
  • It is an effective solvent for aqueous coatings;
  • It has low toxicity;
  • It has a slight odor.


Disperol® ST10 can generally be added at an amount of 0.2-1.0% of the total mass of the watercolor.


Koalesan Disperol® ST10 should be added to the paint after the mineral fillers and pigments have been added and dispersed.

Compatibility with other additives

Disperol® ST10 is compatible with most of the various additives used in watercolors.


The composition of the paint and the dosage of the additive should be determined by laboratory tests.


Additive bulk can be supplied. Additionally, it is possible to supply in the following ways:
In a 30 L canister;
In 200 L plastic barrel;
In 1000 L IBC tank

Storage and expiration date
