Erosion resistant foundry shapes prepared with an epoxy-acrylate cold-box binder
Casting of non-ferrous metals, especially aluminum and magnesium, can have problems with erosion, in which molten metal contacts the mold or core surfaces during the pouring process, resulting in the sand being dislodged. Binder systems addressing this issue often use bisphenol F epoxy resin. A binder system is provided in which a major portion of the epoxy resin component is a bisphenol epoxy resin that has been modified by incorporating oxazolidone rings into an epoxy backbone of the bisphenol epoxy resin, especially a bisphenol A epoxy resin. The modification is preferably achieved by reacting the diglycidyl ether of the bisphenol with a methylene diphenyl diisocyanate.
