Abstract
PURPOSE: The molding sand collapsing agent of improved moldability and collapsing property by mixing cane sugar, glucose and petroleum-base liquid paraffin.
CONSTITUTION: Cane sugar and glucose 100pts.wt. and petroleum-base liquid paraffin 5W100pts.wt. are mixed to apply the waterproof film on the surfaces of cane sugar and glucose. This water-insoluble collapsing agent makes the control and handling of sand easy, improves its moldability, and enables the mold which is high in ordinary-temperature-strength after having been left standing and has marked collapsing property to be obtained.
