PURPOSE: To prepare the titled composition having excellent adhesivity, workability and economical efficiency, and capable of imparting corrosion resistance and paintability to the surface of a metal, by compounding hydrolyzed alkyl silicate, hydrolyzed dialkoxysilane compound, etc. and a specific ionic resin. n CONSTITUTION: The objective composition is prepared by compounding water with (A) 0.5W250g (reduced to SiO 2 per 1l of the objective composition) of hydrolyzed alkyl silicate (hydrolyzable in an organic acid by conventional process), (B) 0.1W250g of a tri- and/or di-alkoxysilane compound (a silane compound having 1W2 organic groups and 2W3 alkoxy groups bonded to an Si atom, e.g. methyltriethoxysilane), and (C) 0.5W250g of a cationic and/or amphoteric resin[e.g. polyalkylene polyamine (derivative)]and if necessary ≤g of a water- insoluble or water-dispersible inorganic material (e.g. fine silica powder). n COPYRIGHT: (C)1982,JPO&Japio |
