The Afcona 2000 Series is a range of silicone-based and non-silicone defoamers and deaerators.
A very strong defoamer, Afcona 2020 is widely used in NC and AC lacquer wood finishes especially applied by curtain coater. It is also suitable for cold cured epoxy as well as UPEs such as MSC, BMC and gel coats. Afcona 2020 may cause some haziness in clear systems.
Afcona 2035 is a universal defoamer for all systems from low to high polar, especially air-drying alkyds, physical drying systems, wood coatings, auto refinishes and general industrial uses. It is a moderate defoamer, well balanced between defoaming and compatibility.
Afcona 2045 is a very compatible silicone-containing defoamer especially created as an updated and more price competitive alternative to earlier Afcona 2025, 2035 and 2040 grades.
Afcona 2045 is particularly suitable for high polar systems such as epoxies, TPA and UPE, and it has an outstanding performance in PU systems.
Organically modified polyalkyl polysiloxane, developed to produce rapid de-aeration for pigmented and matt finish wood coatings, based on NC, AC and PU. It is also suitable for PU and epoxy floorings. Afcona 2280 will also act as a very good levelling agent, giving a smooth surface to the coating.
Afcona 2721 is a special defoamer, tailormade for UV coatings. The carrier used is an acrylate monomer which can take part in the cross-linking. In coatings applications it works in a comparable way to Afcona 2020.
Afcona 2721 has good compatibility and vies good de-aeration as well as good defoaming due to the combination of silicone and non-silicone polymers.
AFCONA 2790 is a polysiloxane defoamer which is suitable for solvent-based silk printing ink systems such as epoxy, PU, UV curing and unsaturated polyester.
AFCONA 2790 can quickly remove the tiny bubbles in the systems, as well as quickly breaking the foams on the interface. It is suitable for high viscosity solvent-based and solvent-free coating and ink systems to anti-foam and remove air bubbles.
