By using phosphate-free cleaners in plants of the hot-dip galvanizing industry, the process costs can be greatly optimized.

For this purpose, the products FAL Cl + FAL Cl / i pure were developed at Foster Chemicals



  • concentration and ratio between surfactant component (FAL Cl) and inhibitor component (FAL Cl / i pure) are variable and can be adjusted as required
  • works already at room temperature
  • very good cleaning properties
  • nearly no sludge formation
  • no rinsing necessary before the pickling step
  • no problems with carrying over of the cleaner solution into the pickling bath
  • phosphate free picking acid is much cheaper to dispose of
