SuperEko KNFCO is an alkaline phenol resin hardened with CO2.
Resin SuperEko KNFCO is used to produce cores for cast iron and cast steel castings. Resin SuperEko NFC is used as the only component of moulding sands and core sands. Moreover, short hardening time allows to use this resin for lot production of cores. Depending on base type and grain size, amount of added resin should range from 2.0 to 3.0 parts by weight. Resin SuperEko KNFCO ensures good knock-out properties and very high casting surface quality. Mixes with this resin exhibit the highest longevity and cores are very strong. Cores made with SuperEko KNFCO should not be stored longer than several weeks.
