Asahi Glass AK-225 Precision Cleaning Solvents

AsahiKlin AK-225 Precision Cleaning Solvents are hydrochlorofluorocarbons (HCFCs) that were designed to replace chlorofluorocarbons (CFCs), perfluorocarbons (PFCs) and other HFCs that had higher ozone depletion potential. AK-225 solvents have lower global warming potential (370) than PFCs and HFCs, however, they are being phased out of production to minimize damage to the ozone layer [see phaseout note].

Their selective solvency, physical properties and ability to form azeotropes made AK-225 solvents good for general and precision cleaning, drying, dewatering and defluxing applications, as well as carriers for silicone and fluorinated lubricants.

Six standard formulations were available: 

  • AK-225 for precision cleaning, as a carrier fluid, for cooling and for other applications where CFC-113, HCFC-141b and PFCs were utilized.

  • AK-225 AES, AK-225 T and AK-225 ATE for defluxing, drying and other applications where CFC-113/alcohol azeotropes and HCFC-141b/alcohol azeotropes were used.

  • AK-225 DH for displacement drying.

  • AK-225 FPL for removing dust particulate and certain types of mold release agents from acrylic resin, stressed polycarbonate and ABS resins.
