TEGO® Antifoam 793 is a 100 % active defoamer concentrate based on polyether-modified siloxanes. TEGO® Antifoam 793 is water dispersible.
Typical Applications
TEGO® Antifoam 793 is suitable as defoamer in aqueous systems and can be applied in a wide range of industrial applications
TEGO® Antifoam 793 can be incorporated into formulation concentrates to obtain low foaming fluids.
The defoamer concentrate is particularly suited as tank side defoamer for post-addition to water-mixed ready to use dilutions.
TEGO® Antifoam 793 is applicable for emulsifiable as well as for water-soluble metalworking fluids and fire-resistant hydraulic fluids.
In mild alkaline cleaners TEGO® Antifoam 793 can be recommended as tank side defoamer.
- Lubricants
- Textile auxiliaries

Benefits at a glance
TEGO® Antifoam 793
Presence of unmodified polydimethylsiloxane (PDMS)
We do not use unmodified polydimethylsiloxane (PDMS) as a raw material during the production of the organo-modified siloxane that is part of TEGO® Antifoam 793.
Based on an analytical method that includes isolation of unmodified PDMS by preparative chromatography and quantification of the isolated fraction, followed by NMR spectroscopic analysis of the isolated fraction, it can be stated that the defoamer TEGO® Antifoam 793 does not contain unmodified polydimethylsiloxane (PDMS) above the treshold of the analytical detection (detection limit of the applied method is 0.1 m%).
- Provides very good foam knock down and hold down properties in a broad range of different aqueous based systems
- Is highly compatible, which allows formulations with excellent stability
- Does not deteriorate the shelf-life of ready to use dilutions
- Is water dispersible that enables its easy handling as tank side additive
- Is free of silicone oil. Therefore, it has no adverse effects on finishing processes (e.g. painting, electroplating) of treated parts
