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.
