    摘要: Broadly, the present invention relates to furan no-bake foundry binders where bisphenol A tar (BPAT) is used to replace a portion of the furfuryl alcohol and any conventional filler optionally included in for binder formulation. Reduction in the amount of furfuryl alcohol in the foundry binder formulation may lead to a reduction in the cost and an improvement in early strength of these formulations. Accordingly, in a furan no-bake foundry binder of a resin derived from a major proportion of furfuryl alcohol and optionally fillers, the improvement which comprises at least a fraction of said furfuryl alcohol being bisphenol A tar. Bisphenol A tar also can replace at least a fraction of any filler included in the binder formulation.

    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: 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.
