Storage and Handling
  • ANIODAC 13P 20-27 should be stored preferably in stainless steel or fibre glass tanks.
  • ANIODAC 13P 20-27 must be stored at temperature below 40°C. Temperature above 45°C should be avoided, even briefly, because hydrolysis may occur with formation of sulphuric acid.
  • Storage tanks must be heated with water warmed at a temperature below 50°C. The use of steam to warm up the product is absolutely prohibited. In addiction contact with acids could cause hydrolysis as well.
  • ANIODAC 13P 20-27 is a clear liquid at room temperature and it can be easily pumped.
  • ANIODAC 13P 20-27 is susceptible to microbial contamination and decomposition by microorganisms.
  • ANIODAC 13P 20-27 is supplied containing a small amount of preservative sufficient for transport and short term storage. If the product is stored for several weeks or months it is recommended to carry out regular check of microbial content.
  • Furthermore careful precautions like clean sampling vessel, sterilized water for dilution, limit prolonged or too often repeated exposure to open air, etc. are necessary to maintain microbiological purity of the product.
