Abstract

The present invention relates to an ultraviolet curable resin composition comprising: 25 to 45 wt% modified epoxy acrylate oligomer; and 10 to 25 wt% urethane acrylate oligomer. The present invention can provide a metal sheet which is transparent, and which has corrosion resistance, impact resistance, scratch resistance, adhesion, anti-corrosion, and bendability (workability) by forming a coating film on the surface of metal materials such as steel materials, specifically steel sheets, using the ultraviolet curable resin composition of the present invention.

Description

technical field [0001] The present invention relates to an ultraviolet curable resin composition and a steel plate using the composition, and particularly relates to forming a coating film on the surface of a steel plate by utilizing an ultraviolet curable resin composition that is not only transparent but also provides adhesion, rust resistance and flexibility. It improves productivity, and can provide an ultraviolet curable resin composition for an environmentally friendly steel sheet without using a solvent, and a steel sheet using the composition. Background technique [0002] Generally, for steel materials such as steel sheets, a coating film is formed on the surface in order to protect the surface, prevent corrosion, and improve the appearance of the material. [0003] Typical methods for forming a coating film on steel materials such as steel sheets include a pre-coated metal (PCM, Pre-Coated Metal) method in which a resin composition such as paint is directly applied...
