Screws used in very aggressive environment require special protection against corrosion.

Due to the excellent corrosion protection even with maximum loads and high temperatures, special coatings are used mainly in the automotive industry and marine technology. Based on the experience of these industries and meeting the expectations of the most demanding customers, we have introduced EsC™ coating (Ecological Suppressor of Corrosion), which is used to protect our products.

EsC™ coating is a combination of perfection and ecology.

The lack of hexavalent chromium guarantees that all our products present in the EsC™ coating are environment friendly.

THE MOST IMPORTANT FEATURES OF ESC™ COATING

1. EsC™ coating is the most effective
   protection against corrosion in the
   most aggressive environments
   (including corrosivity class C4)
2. The elimination of contact corrosion of
   the surface covered with EsC™ coating
   eg. with aluminum
3. High abrasion resistance
4. All products covered with EsC™
   coating undergo salt spray test
   according to PN-EN ISO 9227:2007
   – even more than 1000 hours
   without red corrosion.
