WIPO Patent Application WO/2011/078497

Kind Code:

A3

Abstract:

The present invention relates to a resin composition for pre-coated steel sheet having excellent welding properties, corrosion resistance and workability, to a production method for pre-coated steel sheet produced by using the same, and to the pre-coated steel sheet, and more specifically relates to a metal resin composition for film coating, which comprises a principal resin, a curing agent and at least one metal powder selected from the group consisting of Ni, Co, Mn, Fe, Ti, Cu, Al, Zn, Sn and Fe2P, and in which the mean short-axis diameter (Φ) of the metal powder satisfies the condition t/3 ≤Φ ≤ 3t (where t denotes the thickness of the film which results after the composition has been coated and allowed to cure). Consequently, steel plates which have been coated with the metal resin composition have excellent welding properties, corrosion resistance and workability.
