AFCONA – 2020 is a very strong defoamer for most solvent-based systems, even at low dosages. Strong defoamers work because of their strong incompatibility with the coating system; therefore, even low dosages of AFCONA – 2020 may cause in-can haziness in high-gloss clear coatings. However, its influence on gloss in the dry film is minimal.
AFCONA-2020 has very high defoaming performance as well as anti-foam properties. In most cases, its de-aeration performance is satisfactory. To further improve de-aeration, use in combination with silicone defoamers like AFCONA-2023 or AFCONA-2045 (0.1-0.2% recommended).
AFCONA-2020 is especially suitable for use in the following applications:
- Nitrocellulose lacquers and acid-cured wood finishes, especially those applied by curtain coaters
- Two-component polyurethane lacquers that are applied by spraying or brushing (not including high-gloss finishes)
- Cold cured epoxy resin systems, as well as unsaturated polyester systems (SMC, BMC, and gel coats)
- Heat cured systems applied by curtain coater or dipping
- Any solvent-based system where in-can transparency is not important, such as colored or low-gloss systems.

- Incorporation
- As a strong defoaming agent, AFCONA - 2020 is should be incorporated during pre-mix. If added subsequently, adequate dispersion must be ensured.
- Addition and Dosage
- 0.1 - 0.7% on total formulation. Under normal conditions, 0.15 - 0.30% based on total formulation is a sufficient dosage.
