furan resin sand

    Furan resin - Wikipedia

    Furan resin refers to polymers produced from various furan compounds, of which the most common starting materials are furfuryl alcohol and furfural.In the resin and in the cured polyfurfurol, the furan rings are not connected by conjugation. The resins are generally used as binders for sand castings.

    IFC, the applications of furfuryl alcohol.

    The Furan SO 2 process is a gas cured binder system for the rapid production of small moulds and cores. Curing of the furanic resin occurs right away, when the sand mix is exposed to SO 2 gas at room temperature. [1] FURAN is a generic term for binders containing furfuryl alcohol and either urea or phenol formaldehyde or mixtures of both. [2 .
