Abstract Wet film coating sand includes sand, resin binder, curing agent and organic oil in the amount of 0.01-0.5% sand in its material. Compared with available technology, adding organic oil results in high flowability of the film coating sand and thus compact and smooth sand mold. The raised compactness as well as the viscosity of the organic oil makes the mold core possess certain wet strength.
