Athon defoamers are fluid-containing mixtures of polysiloxanes. In addition, they may contain silica, siloxane resins, functionalized polysiloxanes and other additives. The products can be offered as 100% actives (compounds), in aqueous dispersions, ranging from 10% to 80% of actives, or even in powder form, in which the silicone actives are encapsulated in solid, easy to disperse vehicles in water.
Athon AD 990 Additive is a 100% active silicone-based foam control additive, highly compatible with aqueous systems.
•Effective foam control for water-based coating systems
•Great low-dose performance and wide temperature range
•No impact on surface gloss
•Low viscosity allows easy dispersibility in
waterborne paints and coatings
•Particularly effective in the elimination of microfoam in roller applications
•Acrylic-styrene architectural paints and coatings
•Water-based flexographic inks
•Varnishes for printing application
•PU-acrylic wood coatings

Athon FB 200 Antifoam is a silicone-based powder antifoam formulation.
•Suitable for a wide range of temperatures
•Excellent and lasting antifoam effect, optimum in laundry detergents
Athon FB 200 Antifoam is formulated to give effective release of the active ingredient at low temperatures, while maintaining the antifoam effect even at elevated temperatures. It is great for detergent formulations for low temperature laundry and universal laundry.
Other applications include various powdered products which are also susceptible to foam formation during use such as cleaning products and granular pesticides.

Athon FB 900 Antifoam is a defoamer based on emulsified organic oils. Does not contain silicone.
•Effective at pH range from 2 to 14
•Great deaeration properties
•Great performance regardless of temperature range
•Free of ethoxylated alkylphenols
•Stable in baths with up to 100g/L of sodium chloride and 100g/L of sodium sulfate (defoamer should only be added with fully dissolved salt)
Athon FB 900 Antifoam is used in textile processes:
•Especially suitable for jet dyeing, but has great performance on other dyeing machines as well.
•Quickly removes air and foam.
•Improves the flow of fabric processing in dyeing on jets and winch becks, especially in processes carried out between 40 and 60°C. •In jet dyeing with vat dyes, it is recommended to add the product with the other auxiliaries approximately 3 minutes before adding the dyestuff.
Pre-dilution:
In most cases, the product should not be used directly in concentrated form. A 10% stock pre- dilution can be prepared as follows:
•Add to 10 parts of Athon FB 900 Antifoam in a container.
• Add little by little 10 parts of water at 20 – 30°C, stirring the paste formed by hand. •Adjust to the final volume, adding the remaining 80 parts of water, shaking manually, until obtaining a homogeneous emulsion. Do not use mechanical agitation or direct steam.
•If the dilution is not used immediately, cream may appear. Therefore, it must be shaken manually before using.
In-Process Use: The optimal amount of defoamer varies depending on the type and amount of foaming substance. Commonly used values using pre-dilution of the product to 10% follow.
Pre-treatment:
Scouring, boiling-off, and bleaching baths: 1.0 to 6.0 g/L 10% predilution of Athon FB 900 Antifoam.
Dyeing: Consult Bulletin
Finishing:
•Post-treatment and finishing liquors depending on liquor composition and process speed: 0.5 to 5.0 g/L 10% pre-dilution of Athon FB 900 Antifoam.
•Textile printing; (use of the concentrated product): 3.0 to 5.0 g/kg of pure Athon FB 900 Antifoam, as supplied, in the print paste.
