For over 30 years, Dörken MKS-Systeme GmbH und Co. KG of Herdecke in Germany has been developing and manufacturing micro-layer anti-corrosion systems under the brand name DELTA-MKS^®. What began in 1980 with a vision – namely to establish chrome(VI)-free zinc flake systems as a form of high-performance anti-corrosion protection in vehicle production – has now already been in use in practice for many years and has made the company the market leader and a technological pioneer.

Proximity to the customer is something we take literally – not just in Germany, but all around the world. Therefore, wherever our customers are, we’re there too. And we’re not just simply there: our product managers and employees in our foreign offices are locals, who not only speak our customers’ language but understand what they mean as well. We are thus able to ensure that the high standard in relation to our products is maintained all around the globe. However, no matter in what language we converse, we will provide you with advice on all matters of the application technology, assist you with running in your system and be on hand to offer help at any time. You can thus be sure that together we will always achieve the best possible result.

It all began with springs, spring band clamps and pressed parts, which were coated with Delta^®-Tone as a basecoat and Delta^®-Seal as the topcoat. The system secured its first approval for the automotive industry in 1983 from VW. Today, Delta-MKS^® systems are established and available around the globe and thus it is now impossible to imagine the automotive sector without them. In addition, further areas of use have also been constantly opened up, above all in the wind power, electrical, aviation and construction industries.

A milestone was achieved in the enhancement of the Delta-MKS^® systems with the definition of a new area of application: screws and bolts. As far as their surface technology goes, screws and bolts represent some of the most demanding components of all. At Dörken this tough requirement led to the development of the DELTA-PROTEKT^® product group for threaded fasteners with varying friction coefficient ranges, tailored to the OEMs’ respective needs.

The ultimate breakthrough for the DELTA-PROTEKT^® range was then achieved in 2007 with the implementation of EU Directive 2000/ 53/ EC (‘End-of-Life Vehicle Directive’). Since then, coatings containing chrome(VI) have in practical terms been banned in cars and Dörken MKS Systems has been able to capitalise on the ‘pole position’ advantages of its systems, which from the outset have been free of chrome(VI). The success of the systems and their high level of acceptance in the automotive industry have seen the company develop further. Today, it is a global player – however with a clear commitment to Germany as the site for central development and production. In order to be able to provide customers around the world with technical advice and support in their own facilities, the company began as far back as the year 2000 to develop a system of local branches and to systematically build up its technical network. In addition to the large technology centre in Herdecke, there are now tech centres in the USA, Brazil, South Korea and China as well.

However, the company’s development work has not stopped with zinc flake systems. Since 2010, our field of expertise has been expanded to include ‘green’ electroplating. In future the company will thus be offering solutions for the complete process, ranging from pre-treatment to zinc-plating and passivation procedures and extending all the way to sealing options. To this end the ecologically focussed electroplating systems are being further developed with an emphasis on high-quality, functional protection against corrosion. Just recently opened, an electroplating technology centre will take on a key role in this work.
