CA 2581167

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.

Cette invention concerne une composition de liant comprenant un tanin condensé et de l'alcool furfurylique. La composition peut être utilisée pour préparer des mélanges de fonderie. Ces mélanges de fonderie sont préparés selon un procédé consistant à mélanger la composition avec un acide ou un sel d'un acide. Les mélanges de fonderie sont ensuite mis en forme dans des moules ou des noyaux et durcis par chauffage ou par un procédé à froid utilisant un durcissement catalytique à l'acide plus fort. Les moules et noyaux sont utilisés pour couler des articles métalliques.
