The present invention provides a drainage metal surface treatment agent for forming a surface treatment membrane. The membrane can prevent the metal surface treatment materials and laminated film or a resin film stripping, and closed sex and drug resistance and excellent stability. This invention by containing isocyanate compound (A) more drainage of metal surface treatment agent and solves the above problem, how isocyanate compounds containing two or more (A) after the isocyanate groups. The treating agent optimization further from crosslinking solution containing organic compounds (B1) and crosslinking inorganic compounds (B2) of one or more than two crosslinking compounds (B), in the crosslinking sexual organic compounds (B1) can react with isocyanate groups the functional groups, in the crosslinking of inorganic compounds (B2) can react with isocyanate groups elements. Isocyanate compound (A) preferred for sealing side is studied by using bisulfite urethane prepolymer. |
