SPECIALISTS IN INDUSTRIAL SURFACE COATINGS

Based in Herdecke Germany, Dorken have for over 30 years pioneered the development of thin film zinc lamella coatings which provide exceptional galvanic corrosion protection in thin film coatings.
The functional performance of their coatings can be further enhanced by the application of ‘Delta Seal’ topcoats which help to seal the zinc. The topcoats can additionally provide lubrication which in turn provides a consistent coefficient of friction ensuring consistent clamp loads are achieved when used on threaded fasteners.
Dorken DELTA-MKS® coatings are widely specified in the automotive industry, wind power and are approved (in Germany) for use with potable water.
INDUSTRY SPECIFICATIONS aligned to DELTA-MKS® products can be found below for automotive (Ford, General Motors Holden, Toyota) & windpower (Acciona).
