Product Features
  • AFCONA-2021 offers good compatibility with most resin systems. However, in systems where in-can clarity and dry film transparency are important, the silicone-free defoamer AFCONA 2018 is a better choice.
  • AFCONA-2021 is primarily used in wood coating systems, where it offers good defoaming and acceptable in-can haziness.

 AFCONA-2021 can be used in:

  1. polyurethane coatings for wood.
  2. acid-cured coatings for wood
  3. air-drying alkyd paints for decorative and protective coatings
  4. heat-cured systems for industrial application
  5. NC lacquers for wood, general industrial and car refinish.
