Technical possibilities at Metoba
Metoba offers the following techniques for processing Sealings :Bulk-finishingKorbtechnik
1. Characteristics and properties
Seals are transparent top coats that can be applied to wet, chromated workpieces as a last step. The layer thickness of this transparent layer is controlled over the immersion time and can range from a few tenths of a micrometer to about 2-3µm. Metoba uses chromium-free, organic sealants.
2. Benefits and areas of application
Sealing is a process of chromate-free, organic polymers which combine with the chromated layers and further improve corrosion protection.
3. Basic material
Seals are ideal for galvanized and subsequent chromated components.
4. Required delivery condition
The goods provided must be largely metallically bright. Residual oils or residual impurities must be removable with conventional aqueous alkaline degreasers. Oils containing silicone, alkali/alkaline earth and high-pressure additives must be avoided at all costs.
Workpieces are first galvanized and chromated using a drum process.
