Abstract: A binder composition for making foundry molds comprising an acid hardening resin one or more 5 position substituted furfural compounds selected from the group consisting of 5 hydroxymethylfurfural and 5 acetoxymethylfurfural and one or more compounds selected from the group consisting of urea and derivatives of urea wherein the content of the 5 position substituted furfural compound(s) by percentage is from 1 to 60% by weight of the binder composition. The content of the compound(s) by percentage selected from the group consisting of urea and derivatives of urea is preferably from 0.3 to 10% by weight of the binder composition.

Abstract: A curing agent composition for making foundry molds, comprising 2,6-dihydroxybenzoic acid. In a sand composition for making foundry molds, it is preferable to use simultaneously: an acid-hardening resin which contains both a binder composition for making foundry molds which comprises one or more 5-position-substituted furfural compounds selected from the group consisting of 5-hydroxymethylfurfural and 5-acetoxymethylfurfural, and the curing agent composition for making foundry molds which comprises 2,6-dihydroxybenzoic acid. It is preferable that the content of 2, 6-dihydroxybenzoic acid in the curing agent composition is 10 to 80wt%.
