Abstract
PURPOSE: A resin for covering sand for castings having high strength without causing blockings, etc., obtained by subjecting a phenol, formaldehyde, and a specific aromatic compound to polycondensation.
CONSTITUTION: (A) A phenol is reacted with (B) formaldehyde and (C) a compound[e.g., a by-product in the reaction of 2,2,4-trimethyl-4-(hydroxyphenyl) coumarone with isopropenylphenol, etc.]preferably in a molar ratio of component B/A=5/10W18/10 and in a ratio of 100pts.wt. component A to 10W30pts.wt. component C. The reaction is carried out under heating to give the desired resin.
