Anti-static-type VIEWKOTE™ Pre-coated steel sheet
Features: formability, corrosion resistant, aesthetics, anti-static, eco-friendly, increased efficiency
Anti-static-type VIEWKOTE™ effectively controls static electricity
Nippon Steel & Sumitomo Metal VIEWKOTE™ pre-coated steel sheets are used in the outer cases of a variety of consumer electronics, such as refrigerators, washing machines and air conditioner outdoor units, and this is the anti-static-type that effectively controls static electricity.
Major characteristics of this product
- This is effective at controlling the build-up of static electricity produced by friction from conveyor belts or rubber suction cups in fabrication processes.

Controls static electricity and prevents dirt build-up!
Anti-static-type VIEWKOTE™minimizes electrostatic voltage, as shown below.
Electrostatic voltage comparison (Example)
※* Test conditions A 50100mm piece of neoprene rubber was placed in direct contact with the coated surface of a 70150mm sample of VIEWKOTE™, and immediately after peeling it off, the electrostatic voltage in the coated surface was measured with a non-contact electrostatic field meter.
Using anti-static type VIEWKOTE™can also have dirt build-up preventing effect.
Dirt build-up preventing effect (example) (suction cup marks)
Many of the products that were claimed to have anti-static coatings in the past were based on making it easy for the built up electrostatic charge to be discharged, but in addition to this, anti-static-type VIEWKOTE™has also successfully provided the effect of preventing friction-induced static electricity itself.
In this way, it also prevents dirt build-up in cases where dirt builds up simultaneously with static electricity. This was not readily achieved in previous products.
Major application examples and reference pictures
This can be used for the side panels of refrigerators etc.
