Abstract

PURPOSE: To prevent blocking during transportation and storage by the addition of a specific amt. of a lubricant to a low-molecular novalak resin particle used for the preparation of a resin-coated sand particle for a shell mold.
CONSTITUTION: A low-molecular novolak resin particle obtd. by reacting phenol with an aldehyde in the presence of an acid catalyst is mixed with 0.05W5.0phr lubricant to obtain the titled resin composition. Calcium or zinc stearate, stearamide wax, etc. are suitable as said lubricant.
EFFECT: While a particle not compounded with lubricant tends to cause blocking on standing only for one hr, a particle consisting of the composition of the present invention causes no blocking on standing for 6hr or more.
