  • Binder composition comprising condensed tannin and furfuryl alcohol and its uses
    Patent number: 7407543
    Abstract: This invention relates to a binder composition comprising condensed tannin and furfuryl alcohol. The composition can be used to prepare foundry mixes. The foundry mixes are prepared by mixing the composition with an acid or salt of an acid. The foundry mixes are then shaped into molds or cores and cured by heating or by the no-bake process with stronger acid curing catalysts. The molds and cores are used in casting metal articles.

  • Refractory mixes containing condensed tannin and furfuryl alcohol, and their uses
    Patent number: 7204878
    Abstract: This invention relates to refractory mixes produced by mixing a refractory material with an organic binder and heating to a temperature of typically from about 50° C. to about 100° C. to form a stable composite granulate. The refractor mixes comprise a major amount of a refractory material and a minor amount of a binder composition comprising (a) condensed tannin and (b) furfuryl alcohol. The refractory mixes are used to prepare shaped (e.g. bricks) and unshaped (e.g. blast furnace tap holes, troughs, and tundish liners) refractory products. The invention also relates to a process for preparing the refractory products using the refractory mixes.
