Abstract

PURPOSE: To obtain titled casting sand which is suited for casting of materials of low pouring temperatures and is considerably improved of collapsing property by being coated with the phenolic resin obtained by mixing and reacting synthetic org. fibers of low heat resistance.
CONSTITUTION: The resin coated sand for shell molds obtained by coating sand with the resin obtained by reacting phenols, and scrap fibers of synthetic org. fibers, for example, nylon or polyester, and formaldehydes in the presence of acidic catalysts or alkaline catalysts. The amount of the synthetic org. fibers to be mixed in said resin is preferably in a range of about, for example, 5W40wt%.
