Trouble fitting through new topcoat

A new Dörken MKS Systems topcoat offers optimised threaded connection properties when fitting against parts made of aluminium or against KTL-coated surfaces.

In launching the Delta-Protekt^® VH 301.1 GZ topcoat, Dörken MKS-Systeme GmbH & Co. KG of Herdecke is providing an enhancement of this silica-based seal with integrated lubricant. In particularly difficult applications it prevents stick/slip effects when building chromium(VI)-free surfaces against KTL-coated parts. The new topcoat can also be assembled against aluminium without any problem and thus fulfils the specifications of VW’s new norm 1131-1/2.
