PURPOSE:To reduce rank odors in time of grinding as well as to improve grindability and wheel characteristics ever so better, by using a specific composition. CONSTITUTION:An abrasive resinoid composition contains a dicyclopentadienyl denaturation unsaturated ester compound obtainable by reacting dicy clopentadienyl alpha,beta-unsaturated dibasic acid monoester and polyhydric alcohol and/or diglycidienyl ester compound as well as natural and/or artificial abrasives. In addition, this resinoid composition contains a polymatic monomer, water, an isocyanurate derivative and/or a thermoplastic polymer. |
