Resin Composition for Pre-Coated Steel Sheet Having Excellent Welding Properties, Workability and Corrosion Resistance, and a Production Method for Pre-Coated Steel Sheet and Steel Sheet Using the Same

摘要

A resin composition for a pre-coated steel sheet having excellent welding properties, corrosion resistance and workability, a method of producing a pre-coated steel sheet using the same, and a pre-coated steel sheet are provided. More particularly, a metal resin composition for coating a film is provided. The composition includes a subject resin, a curing agent, and at least one kind of metal powder selected from the group consisting of Ni, Co, Mn, Fe, Ti, Cu, Al, Zn, Sn and Fe₂P powder, and has an average short-axis diameter (Φ) satisfying the condition t/3≦Φ≦3t (where t is a thickness of a dried coating film formed by coating a resin metal composition for coating the coating film). Therefore, the steel sheet to which the metal resin composition is coated has excellent welding properties, corrosion resistance and workability.
