Zinc flake coating

Brief description

The zinc flake coating is a basecoat of zinc and aluminum flakes bonded together by an inorganic matrix. It is applied non-electrolytically to the base substrate and provides long-lasting active cathodic corrosion protection, especially due to the sacrificial effect of the zinc.

Originally developed as a Chrome VI-free alternative to electroplating, zinc flake coating is now the industry standard in a wide range of applications, especially for high-strength steels. One of the reasons for this is that no hydrogen is generated during the application process, virtually eliminating the risk of hydrogen embrittlement.

In addition, the zinc flake coating offers very high dimensional stability combined with a very high corrosion protection effect. Requirements of more than 1000 hours salt spray test according to DIN EN ISO 9227 can be realized with Klever coating technology without any problems.

In addition to a suitable pre-treatment such as zinc phosphating, we are also happy to offer you a downstream finishing with a topcoat individually tailored to your application. By combining a basecoat with a suitable topcoat and/or post-dip lubrication, we are able to completely fulfil your functional requirements, including chemical and media resistance or defined friction and sliding coefficient windows. Component functions such as threads are not restricted.
