To avoid foam- and bubble-formation AFCONA-2723 should be mixed at the beginning of the production/application into the system. If it is added at the end of the formulation, a good dispersion must be ensured.
- Addition and Dosage
0.1 -0.5% on total formulation. In general under normal condition, the dosage is 0.1 – 0.3% based on total formulation

AFCONA-2723 was develop for better compatibility than AFCONA 2720 or AFCONA 2722. However the best compatibility defoamer is still our AFCONA 2724.
AFCONA-2723 is a special additive for thin layer (gel coat), casting resins and epoxy resin systems (e.g. floorings). In addition, it can be used for room temperature curing of unsaturated polyesters, which are used in glass fiber reinforced systems.
AFCONA-2723 can be used in pigmented or non-pigmented resin systems such as:
1) unsaturated polyesters (SMC/BMC gel coats and synthetic mortars)
2) two-pack epoxies
3) Polyester/melamine stoving systems
4) PVC-compounds
In high pigmented and high viscosity system, incorporation of a suitable dispersing agent will reduce the viscosity and this will helps to improve de-aeration. Products like AFCONA – 5010 is suitable for extender rich system and AFCONA – 4070 and AFCONA – 4047 are suitable for inorganic and organic pigments.
Note: AFCONA – 2723 will become slightly hazy at temperatures below 5° C. This will not influence the quality.
