Dorken Introduces New Coating System

The following is a press release provided to GlobalFastenerNews.com. Contact the individual company for additional information.

Grass Lake, MI — Dörken MKS-Systeme GmbH & Co. KG, Herdecke, Germany and parent company of Dörken Corporation USA located here has introduced DELTA-PROTEKT® KL 105, a new coating that provides a two-in-one approach for coating a range of fastener materials such as nuts, bolts and screws.
The coating provides anti-corrosion properties and with its integrated lubricant, a low coefficient of friction.

Anti-corrosion coatings must achieve high levels of quality with thinner coat thickness or reduced number of coats. Process costs, in particular, are becoming increasingly important and represent the highest cost factor in the entire coating process. DELTA-PROTEKT KL 105 was developed with this in mind. The capability of reduced coefficient of friction was added to comply with the specifications of OEMs in mind. Up until its introduction a multifaceted approach was only possible with cost-intensive multi-coat systems.

The coating is applied using either the dip spin, dip coat, spray immerse or spin coat process and dries at a temperature of 190° C and 235° C.  Further processing and its corresponding energy consumption are avoided and there is no time-consuming material change and handling necessary.

DELTA-PROTEKT has achieved more than 1000 hours without rust in the salt spray test (DIN EN ISO 9227) and has a coating thickness between 8-10 µm. The coefficient of friction has achieved a mean value of 0.15 µ tot depending on the coating. 

The coating was awarded the German Material Efficiency Prize by the Federal Ministry and has been approved by a variety of automotive, construction and agricultural OEMs.

Dörken’s global coating solutions are approved for use by and meet the standards and specifications for corrosion protection, sealants, and lubricity performance of fasteners of vehicle manufacturers and Tier One suppliers worldwide yet are environmentally friendly. Its product development programs and manufacturing operations are certified in accordance with DIN EN ISO 9001:2000 and to ISO 14001.
