Abstract

PURPOSE: To provide resin coated sand improved collapsing properties after having for shell molds by coating a novolak type modified phenolic resin contg. the residues of resorcin refining, and cyclopentadiene type oil on molding sand.
CONSTITUTION: The residues of resorcin refining and cyclopentadiene type oil of 100W50,000 centipoises viscosities at 25°C are allowed to coexist in phenols and aldehydes, and are caused to react in the presence of an acidic catalyst, whereby a novolak type modified phenolic resin is obtained. If molding sand is coated by using this resin, the resin coated sand having good nold strength and nolding characteristics and superior collapsing properties of cores or the like for shell molds is obtained. This coated sand is suited for castings of aluminum alloy and the like.
