摘要： Provided are a resin composition for surface treatment and a surface-treated steel sheet coated therewith. The resin composition for surface treatment includes a dispersing element having excellent thermal conductivity and heat dissipation, thereby maintaining physical properties of the conventional anti-fingerprint steel sheet, for example, high whiteness, fingerprint resistance, workability, electric conductivity and alkali resistance, and providing heat dissipation. In addition, the surface-treated steel sheet coated with the resin composition for surface treatment of the present invention has physical properties such as high heat dissipation, electric conductivity and whiteness, and thus may be replaced with a bottom chassis of a backlight unit, particularly, an edge-type backlight unit.

摘要： A chrome-free coating composition for surface-treating a hot-dip galvanized steel sheet that includes carbon nanotubes and has excellent electric conductivity, comprising, based on the total solid weight of the composition: (a) 40 to 60 parts by weight of a water-soluble or water-borne organic resin; (b) 20 to 40 parts by weight of an inorganic metallic sol; (c) 2 to 5 parts by weight of a carbon nanotube paste including carbon nanotube (CNT); (d) 2 to 5 parts by weight of a metal oxide/phosphate-based anti-corrosion agent; (e) 5 to 15 parts by weight of an organic metal complex; (f) 3 to 7 parts by weight of a carbodimide cross-linking agent; and (g) the balance of water, ethanol or a mixture thereof. The steel sheet surface-treated with the composition may be useful to secure corrosion resistance without including a chrome component and shows its electric conductivity even when the coating composition is used at a coating amount of 1000 mg/m2 or more.
