  • 2. Silver180®is a pre-coated steel sheet that can be used in a wide variety of fields and applications due to its following features. 2. Superior scratch resistance Silver180TM has better scratch resistance than ordinary hot dip galvanized steel sheet. 3. Replacement for post hot dip galvanized products (surface-treated in their final shapes) With its attribute to withstand severely corrosive environments, Silver180TM can replace post hot dip galvanized products and thus enable customers to streamline manufacturing processes. 4. Resource-saving and Environment-friendly Silver180TM can be called a resource - saving product since it lasts long and provides excellent corrosion resistance with relatively light coating. Silver180TM can also be called an environment-friendly product since it satisfies requirements of such environmental regulations as RoHS and ELV *. 1.

Silver180TM has harder coating layer than hot dip galvanized steel sheet or hot dip 55%aluminum-zinc alloy coated steel sheet, which gives it better scratch resistance and allows it to be used in applications that are subject to scratching and repeated friction during processing. A sapphire testing needle having a tip radius of 0.05mm was pressed vertically against the test piece with a force of 0.0196-0.196 N (2-20gf). The needle scratched across the test piece for a distance of 20mm. After the surface was visually examined for any scratching, and the minimum load that produced scratching was taken as the scratching load.

The inorganic special treatment chromium-free layer has low electrical resistance and excellent surface conductivity. This gives Silver180TM the same electrical conductivity and suitability for spot welding as conventional materials. With the chromium-free organic film, there is no elution of chromium (Vl) compound and hence chromium-free organic special treatment products are environment-friendly. Enhanced scratch resistance can be attained at roll forming and other processes. The special film provides better corrosion resistance both on flat and processed parts.

Hyper180TM In applications worldwide, Hyper180TM PVDF resin-based metal coatings have demonstrated superior performance and outstanding resistance to film withstand extended exterior exposure to water, humidity, temperature, ultraviolet rays, oxygen and atmo- spheric pollutants. The performance comparisons to the right were compiled by an independent, accredited testing laboratory and are based on actual exposure time. Nothing works better longer. In typical formulations [see shaded areas], Hyper180TM resin-based coatings contain higher fluorine levels than FEVE-based coatings, resulting in greater resiliency, color and gloss retention.
