The effect of the acid catalyst in the sand mixt. is replaced by a synthetic resin contg. a binder of 10-30w/w% of ethyl-or methyl ester of silicic acid. The esters of the silicic acid dissolve well in the mould resin and improve its solid characteristics. Due to the improved quality of the resin a saving in the quantities used is also achieved.
