With at least 1200 hours resistance against red rust, the STAUFF Zinc/Nickel surface coating offers excellent surface protection – even after transport, handling and assembly. This was confirmed by testing in the salt-spray chamber according to DIN EN ISO 9227.

Users across all industries and applications benefit from sophisticated technology, which has been developed for and used by the very demanding automotive industry for many years now and that is already the proven standard for a large proportion of STAUFF components since 2007.

​

• At least 1200 hours resistance to red rust / base metal corrosion under practical conditions in the salt-spray chamber according to DIN EN ISO 9227

• White rust occurs only by way of a slight grey haze

• Surpassing the requirements of the corrosion protection class K5 as defined by the VDMA, the German Engineering Association (360 hours resistance to white rust / 720 hours resistance to red rust)

• Free of hexavalent chrome Cr(VI)

• ELV compliant according to 2000/53/EC (End of Life Vehicles Directive)

• REACH compliant according to 1907/2006/EC (Registration, Evaluation, Authorisation and Restriction of Chemicals)

• RoHS compliant according to 2002/95/EC (Restrictions of the Use of Hazardous Substances)

• Appealing colour scheme with a bright semi-gloss surface finish – comparable to Stainless Steel

• Significantly reduced tendency to corrosion by contact with other metals (such as Aluminium and Stainless Steel)

• Improved abrasion resistance due to the ductility /
  plastic deformability of the coating

• Little to no risk of triggering allergies – nickel release is down to only a fraction of the statutory limits relating to objects which come into direct and prolonged contact with the skin (independent results of the reference test method according DIN EN 1811 are available on request)

• Good paint adhesion properties

• Resistance against all commonly used hydraulic media
