Advantages Using Furan Resin Sand vs.Green Sand

No enrichment of the smelt with hydrogen from the moulding material because the concentration of hydrogen in furan resin sand is less than 0,1%, which is a fractional amount of the concentration of hydrogen in green sand.

That means a much better sharpness of edges, dimensional accuracy and mould stability.
