AFCONA 2720 is an anti-foam and de-aeration additive for use in unsaturated polyesters, coil and can coatings, epoxies and PVC-compounds. It supports the quick deaeration of thermosetting resin systems, allowing for the production of foam-free and blister-free self-leveling compounds and laminates. Additionally, AFCONA 2720 is suitable for use in can and coil coatings, where it is less likely to cause side effects such as inconsistent craters in the line.

Functions: Defoamer

End Uses: 2K (2 component) Coating, Coil Coating, Solventborne Coating

Compatible Polymers & Resins: Epoxies (EP), Melamines & Melamine Formaldehydes (MF), Polyvinyl Chloride (PVC), Unsaturated Polyester (UPE)

Product Applications

​AFCONA-2720 is also recommended for pigmented or non-pigmented resin systems such as:

  1. Unsaturated polyesters (SMC/BMC gelcoats and synthetic mortars)
  2. Two-pack epoxies
  3. Polyester/melamine heat-cured systems
  4. PVC-compounds

In highly pigmented and high viscosity systems, incorporating a suitable dispersing agent will reduce the viscosity and help to improve de-aeration. Products like AFCONA – 5010 are suitable for extender-rich systems, while AFCONA-4070 and AFCONA-4047 are suitable for inorganic and organic pigments.

Incorporation
AFCONA-2720 may be incorporated through simple mixing. A homogeneous mix will increase its efficiency.
Addition and Dosage
AFCONA-2720 may be added at 0.1 -1.0% based on total formulation. Under normal conditions, 0.2 - 0.5% based on total formulation is sufficient.
