    摘要: Broadly, the invention provides for newly available bio-derived formaldehyde-free furanic materials for aggregate binding. A specific example is aggregate binding for forms used in the metal casting process. The inventive binder formulations involve the use of 2,5-furan dimethanol and other “filler” components for high productivity and fast tensile development without formaldehyde, urea, urea-formaldehyde or formaldehyde containing compositions.

    摘要: Difunctional aromatic diamines (e.g. Ethacure® 100 and 300) are derivatized with furan-2,5-dicarboxylic acid (FDCA) to form FDCA-derived bisamides; the derivatives have enhanced curative properties when used as curatives for polyureas, hybrid epoxy-urethanes, hybrid urea-urethanes, chain extenders for polyurethane and polyurea elastomers, and also for reaction injection molding (RIM) products.

    摘要: Broadly, the invention provides for newly available bio-derived formaldehyde free furanic materials for aggregate binding. The specific example case is aggregate binding for forms used in the metal casting process. The new materials make possible higher productivity and lower phenol, formaldehyde, urea, and/or furfuryl alcohol content in the metal casting form-making process. It is expected that the formulations will work well in other aggregate binding situations as well.
