History

The Dörken MKS-Systeme GmbH & Co. KG was founded in 1980 in Herdecke. The start was with the production and distribution of a micro-layer corrosion protection system for a high-performance but heavy metal-free surface protection, from the beginning without the carcinogenic Chromium VI. Originally, small parts were coated with Zinc flake coating and organic topcoats.

Dörken MKS-Systeme has always been exclusively products in Herdecke. Since the year 2000, Dörken MKS started to open up local offices. Today, there are many offices in the U.S., China, South Korea, and locally working product managers in most European countries as well as in India, Taiwan and Brazil.

Products

Zinc flake coatings Zinc flake coating normally consist of a basecoat and topcoat, this is called a modular system.

Basecoats

A basecoat determines the corrosion protection properties of the system and is responsible for cathodic protection. The inorganic basecoats are made of zinc flakes and protect parts with very thin – usually between 8-12 μm. The less noble zinc scarifies itself, and this is called cathodic protection. Due to this phenomenon the more noble steel is protected from for many parts and components, specially designed for fasteners in the automotive-, wind-, electrical-, construction- and aviation industry.

Topcoats

A topcoat complements the properties of the basecoat and influences the chemical/ mechanical resistance of the whole system. They can be organic or inorganic, and offer the ideal seals for the basecoat. The resistance to liquids, chemicals or mechanical stress can be increased, but above all they allow a controlled coefficient of friction. The topcoat is available in many different colors.

Other products

In addition to the most commonly used basecoat (DELTA®-TONE)) and topcoat (DELTA®-SEAL), there are other products of Dörken MKS e.g. DELTA-LUBE ® 10, which is a lubrication with multifunctional properties that match the basecoats.

Moreover, the product DELTACOLL® 80 was developed which is suitable as a top coat especially for electroplated substrates.
