PURPOSE:To provide a case with superior surface hardness, wear resistance, chemical resistance, corrosion resistance, weather resistance, etc., by coating a case surface with a mixture which contains a specified compound, heating it for cross-link curing, to form a film. CONSTITUTION:One kind of the compounds among a silicide containing an epoxy group or its partial hydrolysate shown by a formula 1, a silicide or its partial hydrolysate shown by a formula 2, a halide, an oxyhalide, or a metallic alcoholate of the atoms in the group IV of the periodic table, and a metallic chelated compound having a ligand is used. Then, 88pts. gamma glycidoxy propyl trimethoxy silane and 80pts. tetramethoxy silane are dissolved in 100pts. isopropyl alcohol and a 50pts. solution of 0.05N hydrochloric acid is added and stirred for partial hydrolysis; and aging is carried out and 0.3pts. Sncl2 and a silicone block copolymer are added to prepare a treating solution, which is coated over the case and baked to form a cured film. |
