  • Binder Formulations Utilizing Furanic Components
    Publication number: 20080207795
    Abstract: 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.

  • Polyurethane-forming foundry binders and their use
    Patent number: 5101001
    Abstract: This invention relates to no-bake foundry binders and a no-bake process for preparing foundry shapes which utilizes polyurethane-forming foundry binders. The binders are unique because the isocyanate component preferably contains no solvent and the weight ratio of the phenolic resin component to isocyanate component is atypical. It has been found that the use of these binders in a no-bake process produces foundry shapes with improved tensile strengths.
