Application
Antifoam-ASD is stable to acidic , alkaline pH and at elevated temperature. Depending upon the requirement 0.1 - 0.5% Antifoam-ASD can be used.
Note: Recommended dilution 1:1 to 1:10. For high dilution, stability can be extended by addition of small amount of thickener i.e. Xanthan gum or Polyacrylates.
Preservation: It is recommended to add 0.1% Bronopol (2-Bromo,2-nitropropane, 1,3-diol) or Methyl Paraben (methyl para hydroxy benzoate) as an antimicrobial agent to avoid fungal / microbial growth.
Storage : Store in cool, ventilated shed away from heat and direct sunlight. Storage temperature should not exceed 35 deg c. Close lids firmly to avoid contact with air and moisture.
Shelf Life : 9 months from the date of manufacturing, if stored under controlled conditions.
