PURPOSE:To obtain the title composition capable of uniformly forming a lubricating film in the case of application of the compound to a high-temperature material to be treated by dispersing a solid powder lubricant into a dispersion medium containing a large amount of high-boiling solvent in the presence of a surfactant. CONSTITUTION:(C) 0.5-30wt.% (preferably about 5wt.%) solid powder lubricant comprising boron nitride powder, graphite powder, molybdenum disulfide powder, talc powder, etc., having preferably <=1mum average particle diameter is dispersed into (A) a disperse medium containing >=50wt.% solvent such as trialkyl phosphate having >=180 deg.C boiling point under 1 atmospheric pressure in the presence of (B) <=10wt.% (preferably <=2wt.%) surfactant of preferably nonionic base to give the aimed composition. |
