As long as possible, we will continue to offer classic chromating in our product range. These include:
On all zinc deposits, deep black, corrosion-inhibiting chromate layers are applied with the utmost uniformity.
Dark olive-colored coatings with excellent corrosion protection are produced on the zinc layer to be chromated.
Saphirblau FF is a liquid, fluoride-free blue passivation that produces clear blue, cloud-free layers on all acid, cyanide or cyan-free electrolytes. The passivation has a gloss-increasing effect and can be used both in rack and drum operation. It is a chromium-III-based product; hexavalent chromium compounds and dyes are not included.
The yellow passivation Helios 2.0 creates slightly iridescent, strong yellow coatings on all galvanically applied zinc layers, which have a high level of corrosion protection and have a gloss-retaining effect. The yellow passivation is supplied in two parts in liquid form and is free from cobalt, fluoride, dye and chromium VI compounds.
Eloc-6 creates a chromium-VI-free layer on galvanically applied zinc layers, which meets very high corrosion protection requirements. Adhesive, transparent layers are applied by simply immersing them in an aqueous solution, which can also serve as the basis for subsequent sealing. Different shades of color can be achieved by varying the working conditions. It can be tempered and subsequent coating with top coats is possible.
The Dekapass MKB is a new type of zinc passivation system and the latest in-house process. It is free from chromium VI and fluoride; a cobalt-free variant is being tested. As easy to use as a traditional thick-film passivation, a corrosion protection comparable to zinc-nickel systems is created on galvanically applied zinc layers. However, sealing is no longer required to achieve this level of corrosion protection, unless sealing is required from another side (e.g. for a defined coefficient of friction). According to the first independent test results from practice, the simple description of "thick film passivation" does not do justice to the performance achieved by this system. In terms of the corrosion protection behavior achieved, the zinc layer can best be described as quasi-inert.
This is a clear, alkaline, water-based copolymer emulsion which, after chromating or passivation, can be applied to the workpiece simply by dipping and drawing. A spray and dip-spinner application (centrifuge) is also possible.
This sealing is a further development of Aquaplat # 47 to meet the special requirements of modern climate change tests with improved flow and edge masking effects. The application is as easy as with the Aquaplat # 47.
As the name suggests, this process is not a seal, but the cleaning system that goes with the sealing processes. It is used especially for the residue-free removal of seals based on polyacrylate copolymers and is matched to the aforementioned seals. Workpieces as well as racks and drums can be unsealed.
