Deuteron® ES 224 is a synthesized compound originating from multifunctional organic bases and fatty acids, primarily within the C14–C20 chain length, predominantly C18. Specifically designed as a defoamer for unsaturated polyesters, it enhances both pigment and substrate wetting. This solution is characterized by its clear, yellow-liquid appearance.

Product Highlights
  • Deuteron® ES 224 is a synthesis product of multifunc- tional organic bases and fatty acids with chain length from C14 to C20, mainly C18. It is used as defoamer in unsaturated polyesters and leads to improved pigment wetting and substrate wetting.
  • The defoaming properties of Deuteron® ES 224 are based on deaeration and prevents formation of foam in UPE systems actively. The product is particularly suitable for thixotropic systems, as it does not negatively influence their rheological properties.

Applications & Uses

Application and Dosage Information

Deuteron® ES 224 is suitable in unsaturated polyester systems and especially improves performance in:

  • Wetting and dispersing additive
  • Metal coatings
  • Deaeration in dispersing and grinding processes
  • Substrate wetting


  • 0.5 % based on the polyester resin solution.


  • Deuteron® ES 224 can be added to the resin solution by the UPE manufacturer. To further adjust system per- formance, it is possible to add Deuteron® ES 224 at the processor’s site just before addition of the peroxides. The stirring conditions should be selected so that the system is not unnecessarily loaded with air bubbles.
