AFCONA 2020 is a very strong defoamer suitable for most solvent-based coatings, printing inks, and thermosetting resin systems. It eliminates foam and blistering, regardless of the source of the air bubbles. However, it is not suitable for transparent, high-gloss clear topcoats.

Functions: Defoamer

End Uses: 2K (2 component) Coating, Clearcoat, Lacquers, Solventborne Coating, Solventborne Ink, Top Coat

Compatible Polymers & Resins: Epoxies (EP), Nitrocellulose, Polyurethanes (PU), Unsaturated Polyester (UPE)

Labeling Claims: Silicone-free

Product Features

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:

  1. Nitrocellulose lacquers and acid-cured wood finishes, especially those applied by curtain coaters
  2. Two-component polyurethane lacquers that are applied by spraying or brushing (not including high-gloss finishes)
  3. Cold cured epoxy resin systems, as well as unsaturated polyester systems (SMC, BMC, and gel coats)
  4. Heat cured systems applied by curtain coater or dipping
  5. 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.
