t the Fastener Fair 2017 Parts with this system in Stuttgart Dörken structure offer highest MKS-Systeme GmbH & corrosion resistance, with Co. KG, Herdecke, presented its peak values of up to 2,000 complete portfolio of products hours in salt spray testing for the surface coating of screws (SST) according to and other fasteners, under the DIN EN ISO 9227. slogan “The Corrosion Experts”. Special plant technology The spectrum ranged from zinc enables the material to flake coating to KTL technology also be applied to screws 2.0 and on to the and other fasteners, DELTA-PROZINC® galvanic as the application of protection system. DELTA-eLACK® in the drum To illustrate the performance enables the coating of 1 small to medium-sized capabilities of the individual systems coated parts that had components as Figure 1: In Stuttgart Dörken MKS-Systeme presented its full product portfolio in been subjected to various test bulk goods. the field of zinc flake, electroplating and KTL. cycles were displayed on the All surface coating stand (Fig. 1). Screws protected systems from the portfolio displaying comparable values to standard by zinc flake systems not only proved of Dörken MKS feature high performance zinc nickel systems. The process-safe, their capability in the DIN EN ISO 9227 and a global quality standard, assured salt spray test, in which they displayed highly-efficient system offers an overall through a worldwide network of 150 licensed package of pre-treatment products, zinc no white rust formation compared to coaters (Fig. 2). baths, passivation and top coats with no galvanic coatings, even after 240 hours. For further information: The benefits of cathodic corrosion need for nickel and cobalt. DELTA-PROZINC® www.doerken-mks.de also features protection with zinc flake systems were superb fastening particularly evident in screws subjected to cyclical tests such as the ACT I and characteristics and can be adjusted II climatic extremes tests (Accelerated to the respective Corrosion Test) of Swedish vehicle coefficient of friction manufacturer Volvo or the VW PV 1209 requirements via top corrosion protection test. Despite their coats with integrated superb corrosion protection properties, lubricants. zinc flake systems only have a total coat The KTL 2.0 system thickness of 8 to 12 μm on average and are combines the therefore particularly well-suited to use in organic top coat components requiring a maximum fit, such as screws with metric threads. DELTA-eLACK® with ® its premium, deepThe DELTA-PROZINC electroplating system 2 performed well in comparison to yellow black appearance chromating, with corrosion resistance with the cathodic Figure 2: The Corrosion Experts: the combined manpower behind this times of up to 720 hours in salt spray corrosion protection slogan is illustrated by a collage on the stand, depicting the Dörken MKS-Systeme team in action. testing according to DIN EN ISO 9227, of zinc flake coating.
