Problems solved by technology

[0009] However, no matter which method, it is impossible to obtain a film with excellent corrosion resistance that can replace the chromate film on the surface of the metal material, so in fact, the aforementioned problems cannot be solved.
Therefore, still fail to obtain a kind of chromium-free surface treatment agent and surface treatment method that metal materials with excellent corrosion resistance are used at present

Abstract

A metal article whose surface is coated with a coating composition composed of (A) a silane coupling agent component, (B) a polymer component having a specific chemical structure, and (C) a wax component provides a chromium-free surface treated metal material with superior corrosion resistance, paintability, fingerprint resistance, and workability.

Description

technical field [0001] The present invention relates to the invention of a metal plate material which can be used for home appliances, building materials and the like and has excellent corrosion resistance, paintability, fingerprint resistance and workability. Background technique [0002] Generally speaking, metal sheet materials such as steel sheets, aluminized steel sheets, zinc-containing steel sheets, or aluminum sheets are widely used in the fields of automobiles, building materials, and home appliances. However, zinc or aluminum will often corrode in the atmosphere to form corrosion products (ie "white rust"), which will not only cause poor appearance of metal materials, but also adversely affect paintability. When the product is manufactured through various steps, oil stains such as fingerprints are often attached to it due to the processing by the operator, and there is a concern that the value of the product will be significantly reduced. Oil etc. need to be remov...
