Recommendation & Method of use:
MARK IC 2451 is recommended for formulations where air-entrainment cause
operational difficulties or impairs the quality of the product.
For fiber reinforced spray-up and hand lay-up resins, adhesives and cobalt-accelerated putty compounds, from 0.25 to 0.5% of defoamer on the weight of the solids is usually sufficient to suppress air-entrainment.
