XIAMETER® Silicones Simplified - from Dow Corning

XIAMETER® brand Silicone Antifoams

Silicone Antifoams


Silicone antifoams can be used as:

  • Formulation and processing aids
  • Defoamers and foam preventers

Silicone antifoams are used in many industries

  • Reduce foam created during the production and use of laundry detergents, pulp and paper, food processing and during textile dyeing.
  • Enhance chemical manufacturing processes such as mixing, bottle filling, gas scrubbing, distillation, emulsion polymerization, filtration and fermentation.



Advantages of Silicone Antifoams

XIAMETER® silicone foam control agents are available as fluids, compounds, emulsions and powders, and are suitable for use in both aqueous and non-aqueous systems.

  • Effective at much lower dosage rates than organic antifoams, leading to lower cost-in-use
  • Silicone antifoams tend to be much more persistent (longer lasting) than organic antifoams
  • They tend to be less reactive in the foaming medium, leading to fewer compatibility problems
  • Silicone antifoams are stable over a wide range of temperatures and pH levels


Composition of Silicone Antifoams

  • Silicone antifoam compounds are composed of silicone fluids and silica.
  • Silicone powdered antifoams are composed of silicone antifoam compounds and solid carrier.
  • Silicone antifoam emulsions are stable blends of silicone antifoam compounds and water.
    - Silicone antifoam compound (dispersed phase)
    - Water (continuous phase)
    - One or more surfactants
    - Stabilizing and performance-enhancing additives (such as thickeners, wetting agents, biocides, rust inhibitors and freeze-thaw protectors)
