- Product Properties
AFCONA-2720 supports the quick de-aeration of thermosetting resin systems, so that foam and blister-free self-leveling compounds and laminates can be processed. In can and coil coating, choosing a defoamer is very critical. A wrong choice will result in inconsistence occur of crater in the line. AFCONA - 2720 is the suitable defoamer for this application as it gives very little side effects like others defoamers do. AFCONA-2720 can be used in pigmented or non-pigmented resin systems such as: 1) unsaturated polyesters (SMC/BMC gelcoats and synthetic mortars) 2) two-pack epoxies 3) Polyester/melamine stoving systems 4) PVC-compounds. In high pigmented and high viscosity systems, incorporation of a suitable dispersing agent will reduce the viscosity. This will help to improve de-aeration. Products like AFCONA – 5010 is suitable for extender rich systems and AFCONA – 4070 and AFCONA – 4047 are suitable for inorganic and organic pigments.
