Product Properties

 AFCONA-2018 is a silicone-free defoamer for various coating systems. It functions well during the application of paints and lacquers. Also prevents the entrapment of air during processing steps such as stirring, pumping etc. AFCONA-2018 has very good compatibility properties, which makes it extremely suitable for use in clear and high gloss coatings. It is also suitable for thick clear coatings applied by conventional spraying where dry film transparency is very important.

AFCONA-2018 is very suited for solvent-based wood finishes where foaming is a problem when applied by spraying. AFCONA-2018 is especially suitable for systems listed below where transparency (in-can and dry film) is important and still give good defoaming effect:
1) polyurethane coatings for wood except acrylic based
2) acid-curing coatings for wood and etching/wash primers
3) NC lacquers for wood
Due to the good compatibility, AFCONA-2018 also can be used in resin manufacturing as pre-added defoamer, except for acrylic-OH.
Remark: AFCONA – 2018 is not recommended for Acrylic systems.
