SheraTop®-System
The SheraTop®-system is a modern duplex system based on the well-established and proven Sherardizing with excellent corrosion protection.
- The sherardizied basecoat is alloyed with the base metal and joins very well to the following topcoat.
- The diffusion layer protects the base metal actively (cathodic). The duration of protection is adjustable through the thickness. A layer thickness between 10 microns and 100 microns can be generated.
- Depending on the requirements, the basecoat is Cr VI-free passivated, or combined with other topcoats to form a duplex system.
- Relevant properties such as chemical resistance, friction, or a color-coordinated appearance can be defined according to customer specifications.
The SheraTop®-System provides excellent solutions for different industries:
- In the construction industry sherardized and passivated products are used.
- In the offshore industry a combination of Sherardizing with PTFE topcoats provides excellent corrosion protection.
- The automotive industry uses sherardizied Products with friction coatings or rubber linings for damper systems.
- Some customers use sherardized products to post-treat these e.g. after assembling or forming.
The SheraTop® system provides with special Topcoats corrosion protection of up to 5000 h NSS.
