Powder and liquid novolac (phenol-formaldehyde) resins, furan type resins for foundry applications.
 
RI Chem’s products for foundry are the powder and liquid novolac and the furan type resins. The powder novolac is used to provide tensile strength while the liquid novolac is used in the cold and hot coating of sand in the manufacture of shell molds and cores. The furan type resin, intended for large core or mold production, is acid-catalyzed at ambient temperature.
