CONSTITUTION: To (A) phenolic resin, is added (B) 1W30, preferably 5W20wt% of a compound of the formula [the reaction product from 2,2,4-trimethyl-4(hydroxyphenyl)coumarone and isopropenylphenol] to give said composition. Further, to 100 parts by wt of the composition are added 0.025W1.2 parts of sand particles and a curing agent as hexamethylenetetramine and the mixture is used as sand particles covered with resin.
