PURPOSE:To produce the titled composition, containing a condensate of a specific organoalkoxysilane, colloidal alumina, water and alcohol in a specific proportion and having improved heat resistance, adhesive property, preservation stability, etc., and capable of applying films having a high hardness to stainless steel, etc. CONSTITUTION:A composition, obtained by containing (A) 100pts.wt. (expressed in terms of organoalkoxysilane) organopolysiloxane which is a condensate of an organoalkoxysilane, expressed by the formula RSi(OR')3 (R is 1-8C organic group; R' is 1-5C alkyl or 1-4C acyl) and having 3,000-50,000 weight- average molecular weight expressed in terms of polystyrene, (B) 5-50pts.wt. (solid content) colloidal alumina, (C) 10-80pts.wt. [including water in the component (B)] water and (D) >=120pts.wt. alcohol and curable at 80-300 deg.C for 10-120min without gelatinizing for a long period in spite of water contained therein and usable in various materials.
