Product Features
  • AFCONA-2025, AFCONA-2035 and AFCONA 2040 have similar chemical structures with different modifications. However, their performance is very different in some systems. We recommend customers try all three products to select the most suitable defoamer for their system.
  • AFCONA-2025 is recommended for brush and conventional spray applications. It is very suitable for systems ranging from low polarity to high polarity.
