Metallic Surfaces

Metallic Surfaces - Sol-Gel Hybrid Systems

Since 2005, we have been developing, formulating and producing functionalised special coating systems for metallic & mineral surfaces.
Another focus of our development work is the special coatings with antimicrobial effect on metal surfaces, mineral and plastic surfaces.

Aluminium

Interlotus aluminium coatings are preferred by industrial manufacturers and users on coil coating lines. They offer multiple advantages for a finished and high-quality aluminium surface.
- High transparency
- Glazing
- Anti-fingerprint
- Easy-to-clean
- Scratch resistance

Stainless Steel

Stainless steel in various qualities is "quite soft" and very sensitive to scratches and is therefor foiled before further processing. Usually plastic foils are used. At the end user, the foil has to be removed and the sensitive surface comes into operation.

Therefore, stainless steel surfaces should already be protected before foiling. Interlotus products protect against scratches, facilitate cleaning with an easy-to-clean effect and prevent unsightly fingerprints with an anti-fingerprint effect. If required, the stainless steel coating can be equipped with an antimicrobial effect.
Anti-fingerprint & easy-to-clean properties
Both properties create hygienic advantages in
clinically demanding situations.

Galvanised steel

Hot-dip galvanised and electro-galvanised steel have more or less medium to good corrosion protection, depending on the zinc protection layer. For sophisticated and long-life surfaces, we suggest our additional ultra-thin, paintable conversion coatings. These are coil coating products that can significantly improve corrosion protection and sliding properties with very thin layers ≤ 1 µm.

Interlotus products for galvanised steel have the following properties:

- Applicable conversion coating
- Various corrosion protection classes from temporary to 1000 h NSS
- Corrosion protection at S ≤ 10 µm, 1000 h NSS
- Primer function
- Anti-fingerprint
- Improvement of sliding properties during further processing
- Customer-specific colours / colour settings

With these products, we create thin-film added value that contributes positively to production improvement, durability and environmental protection.

Steel / Black steel

Untreated black steel gets red rust very quickly. Depending on the requirement profile, Interlotus can offer you a temporary corrosion protection.

Steel pipe - temporary corrosion protection

The aim of temporary corrosion protection is to achieve a sufficient corrosion protection effect on the components during the production process, storage and transport.

Zink

Zink Oberflächen genießen den Ruf der natürlichen Langlebigkeit. Hierbei durchlaufen sie den natürlichen Prozess der Alterung (Patinabildung) mit optischen Veränderungen. Um diese Prozesse kontrolliert stattfinden zu lassen, werden technisch aufwändige Konversionsschichten oder Phosphatierungen auf das Zinkmaterial aufgebracht. Diese Schutzschichten sind wiederum empfindlich gegen mechanische Einwirkungen und Korrosion.

Deshalb hat Interlotus speziell für phosphatierte Oberflächen, dünnschichtige, langlebige Korrosionsschutzbeschichtungen entwickelt. Ebenso haben wir für walzblanke Oberflächen, Coil Coating Lacke für verschiedene Anwendungen entwickelt.

InterLotus HPC Color - Bright Rolled Zinc

InterLotus HPC - High Performance Coating kann direkt auf walzblankes Zinkblech appliziert werden. Das Beschichtungsverfahren ist nachhaltig und Ressourchen schonend. Der Arbeitsschritt der Phosphatierung kann entfallen. Sie sparen Kosten, Zeit und Material.
