Patent abstract
This invention relates to a heat-cured furan foundry binder system comprising a furan binder and a furan monomer or oligomer containing at least two terminal hydroxymethyl groups. The binders are particularly useful as warm-box binders, because they cure faster and foundry shapes (typically cores and molds) made with the binders exhibit higher tensile strengths than those made with conventional heat-cured furan binders.
