TEGO ANTIFOAM 2-89

TEGO Antifoam 2-89 is an antifoam emulsion based on Polyethersiloxane.
TEGO Antifoam 2-89 is an organo-modified siloxane. 
TEGO Antifoam 2-89 is an antifoam emulsion that provides reliable foam control and excellent long-term efficiency especially in pressure sensitive adhesives. 

TEGO Antifoam 2-89 is an antifoam emulsion based on organo-modified siloxanes.
TEGO Antifoam 2-89 combines excellent efficiency with maximum compatibility at the same time. 
These properties cannot be achieved with organic or with traditional silicone oil based antifoams. 
Required dosage may vary over a wide range (0.05-0.2%).

Applications of TEGO Antifoam 2-89
TEGO Antifoam 2-89 provides reliable foam control and excellent long-term efficiency especially in pressure sensitive adhesives. 
TEGO Antifoam 2-89 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 of TEGO Antifoam 2-89
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:
• Foam formation during compounding of a final formulation
• Foam formation during the application of the adhesive
• Inadequate storage stability 

Dosage of TEGO Antifoam 2-89:
In most applications TEGO Antifoam 2-89 is beneficial to apply TEGO Antifoam 2-89 pre-diluted in water (1 : 1 to 1 : 10).
Depending on the application in question the required dosage may vary over a wide range (0.05 - 0.2 %). 
Suitable screening tests are therefore recommended (initial dosage: 0.1 %).

Handling of TEGO Antifoam 2-89:
Dilution of TEGO Antifoam 2-89 may be prepared by adding the desired amount of water to TEGO Antifoam 2-89 while stirring gently at low shear rates. 

Storage stability
TEGO Antifoam 2-89 is stable in closed containers for a minimum of 6 months.
TEGO Antifoam 2-89 must be stored in frostfree conditions.
