Surfaces for bonding applications

With the development, introduction and expansion of Klever's own product portfolio with Klevercol®, KleverPUR® and the KleverPLAST® Group, we have achieved new levels of innovation in coating for subsequent bonding applications.

Sustainable products for the functional coating of surfaces for highly efficient adhesives on almost all basic substrates.

Bulk material application

In the bulk material sector, we protect your components reliably and long-lasting against corrosion and, if required, add further functions such as defined friction and sliding windows or adhesion promotion. We protect both small, filigree parts with a diameter of 1.8 mm and large components with a diameter of up to 200 mm with, among other things, our own application process Kleverest®

Kleverest® process

With the self-developed and continuously optimised Kleverest® process technology, we enable the process-reliable application of exact coating thicknesses in the micrometre range.

This self-developed immersion centrifugal process is particularly impressive for its reliability with geometrically complicated bodies, hollow and scooped parts, screws with the smallest internal threads and nuts. It is precisely here that conventional application methods reach their limits, even though reliable corrosion protection without functional restrictions is indispensable.

Diving slingshot application

The dip-spin process is a common method for coating bulk material. Zinc flake coatings, top coats as well as post-dip lubrications can be applied.

Electrophoretic coating (E-Coating)

Cathodic dip coating (CDC) is an electrochemical process used to apply topcoats as a sealant to zinc flake coatings, other electroplated zinc and zinc alloy coatings, stainless steels, zinc and aluminium die castings.

Rack applications

In the field of rack application, we protect your components reliably and long-lasting against corrosion and add functions such as defined friction and sliding windows or adhesion promotion. Our product portfolio ranges from fasteners and fixing elements to components for bonding applications.

Full coating

The industry-standard, full-surface rack application is an easy-to-implement application process that is used for a large number of components.

We use several fully automated systems and, in addition to our proprietary Klevercol®, KleverPUR® and KleverPLAST® coating agent groups, we also use a wide range of other coating agents to fulfil all your wishes and complex requirements.

Partial coating for fasteners

Our partial coatings for fasteners, for example head coatings for screws, not only offer a first-class, decorative appearance, but also functional enhancements for your components.

Our extensive range of coating options enables you to obtain the exact surface and colour to suit your requirements and area of application.

Trace Coating

The fully automated, partial coating process Trace Coating is our latest innovation that takes both resource and energy efficiency to a new level.

We are also researching the integration of artificial intelligence here in collaboration with the TH Cologne as part of a state-funded ZIM project.
