Binder Formulations Utilizing Furanic Components

摘要

Broadly, the invention provides for a cold-box aggregate binder typically being a mixture of phenolic or urea resin and a furanic material selected from one or more of the group consisting of 5-hydroxymethyl furfural (HMF); 2,5-furan dimethylol (FDM); 2,5-furan dicarboxylic acid (FDCA); 2,5-diformyl furan (DFF); FDCA monoalkyl ester (hemiester); FDM-ether; and HMF-ether; that cures in the presence of a catalyst gas.
