- Addition and Dosage
0.1- 1.0% on total formulation. In general under normal conditions, the dosage is 0.20 – 0.50% based on total formulation.
- Incorporation
As a strong defoaming agent, AFCONA- 2050 is recommended to be incorporated prior during pre-mix. If added subsequently, good dispersion must be ensured.

- Typical Properties
- Product Properties
AFCONA – 2050 is a unique defoamer. It has very strong defoaming and anti-foam performances with additional good leveling. This in contrary with most of the other defoamers, which influence the leveling performance negatively. AFCONA-2050 is suitable for solvent- based coatings, printing inks and thermosetting resin systems. It eliminates foam and blistering, regardless whether the air bubbles are caused by the substrate. As mentioned, AFCONA-2050 has very strong defoaming as well as anti-foaming properties. In most cases, the de-aeration property is satisfactory. To improve further the de-aereation performance, a combination with silicone defoamers like: AFCONA-2023 or AFCONA2045 at 0.1-0.2% is recommended.
AFCONA-2050 is particularly suitable for the following applications:
1) Nitrocellulose lacquers and acid-cured wood finishes especially those applied by curtain coaters
2) Two-component polyurethane lacquers, except for high gloss clear (due to it high incompatibility), which are applied by spraying or brushing
3) Cold cured epoxy resin systems, as well as unsaturated polyester systems (SMC, BMC and gel coats)
4) Baking paint applied by curtain coater and dipping
5) Any other solvent based system where in-can transparency is not important likes colored and matted systems. Note: Not suitable for air drying alkyd systems
