PURPOSE: To obtain the subject composition suitable for bonding a carbon- containing refractory such as f dipping nozzle, etc., for continuous casting of steel by blending a solution of a resol type thermosetting phenolic resin with specific thermosetting phenolic resin powder and a refractory material.
CONSTITUTION: The objective composition is obtained by blending (A) 10-25wt.% (optimally 20wt.%) solution of a resol type thermosetting phenolic resin in an alcohol with (B) 1-5 wt.% (optimally 3wt.%) thermosetting phenolic resin powder containing a benzylic ether type phenolic resin and (C) a refractory material such as Al2O3 and making up the total weight to 100wt.%. Furthermore, Al.Mg alloy powder or metallic Al powder or both are preferably blended.
