AFCONA 2723 is a defoamer and air-releaser for unsaturated polyester, polyurethane, UV, and epoxy resin systems. It is recommended for thin-layer (gel coat), casting resins, and epoxy resin systems (e.g. floorings), as well as for room temperature curing of unsaturated polyesters used in glass fiber-reinforced systems.

Functions: Defoamer

Chemical Family: Silicones

End Uses: 2K (2 component) Coating, Clearcoat, Coil Coating, Gelcoat, Solventborne Coating, Solventless & High Solids Coating, Wood Coating

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

Labeling Claims: Not Listed In California Proposition 65

Product Features

AFCONA-2723 can be used in pigmented and non-pigmented resin systems such as:

  1. unsaturated polyesters (SMC/BMC gel coats and synthetic mortars)
  2. two-pack epoxies
  3. polyester/melamine heat-cured systems
  4. PVC-compounds

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

Applications & Uses

Compatible Substrates & Surfaces
Incorporation
To prevent foam - and bubble-formation, AFCONA-2723 should be added at the beginning of the production process or application into the system. If it is added at the end of the formulation, good dispersion must be ensured.
Addition and Dosage
0.1 -0.5% on total formulation. Under normal conditions, 0.1 - 0.3% based on total formulation is sufficient.
