TEGO® Antifoam 2-89 is an antifoam emulsion based on organo-modified siloxanes.
Typical Applications
TEGO® Antifoam 2-89 provides reliable foam control and excellent long-term efficiency especially in pressure sensitive adhesives. It may also be used in aqueous media, as well as in the processing and application of polymer dispersions, emulsions and a multitude of other industrial applications (e.g. industrial and household cleaners) where the use of traditional silicone oil based antifoams is restricted for certain reasons.
Benefits at a glance
The special raw material of TEGO® Antifoam 2-89 provide an unique product profile that combines excellent efficiency with maximum compatibility at the same time. These properties cannot be achieved with organic or with traditional silicone oil-based antifoams.
Furthermore undesirable effects associated with silicone based antifoams (silicone spotting, fish eyes) can be eliminated in most applications.
The TEGO® Antifoam product range exceeds customer requirements according to:
TEGO Antifoam 2-89 is free of silicone oil (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 2-89. 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 2-89 does not contain unmodified polydimethylsiloxane (PDMS) above the treshold of the analytical detection (detection limit of the applied method is 0.1 m%).
Furthermore undesirable effects associated with silicone based antifoams (silicone spotting, fish eyes) can be eliminated in most applications.
The TEGO® Antifoam product range exceeds customer requirements according to:
- Foam formation during compounding of a final formulation
- Foam formation during the application of the adhesive
- Inadequate storage stability
