Zinc Flake Coatings
Zinc Flake Coatings
Introduction to Zinc Flake Coatings-
Zinc flake coatings are advanced, non-electrolytic anticorrosion systems designed for automotive, construction, and
industrial components. They provide a thin, uniform barrier layer that delivers long-lasting protection without altering
dimensions. Their biggest advantage is no hydrogen embrittlement, making them ideal for high-strength fasteners.
Key Benefits of Zinc Flake Coatings
Superior corrosion resistance (up to 1000–2000 hours SST)
Thin coating thickness (5–20 microns)
No risk of hydrogen embrittlement
High chemical and heat resistance (up to 300°C)
Eco-friendly and fully RoHS/REACH compliant
Excellent adhesion for topcoats and lubricants
Geomet Coatings
Introduction to Geomet Coatings
Geomet is a globally trusted, water-based zinc–aluminum flake coating offering exceptional corrosion protection with
extremely thin layers. Used extensively for fasteners, chassis parts, and industrial hardware.
Corrosion Protection
GEOMET® 500 alone or in combination with our range of topcoats passes the most severe corrosion cyclic tests. It
protects parts from rust even after mechanical damages, such as stone chipping, thanks to its self-healing property. It
also ensures bimetallic compatibility with aluminum alloys. Its nominal thickness can be adjusted (from 6 to 15 μm and
from 1 to 3 layers depending the type of application process) to meet the expected performance
Lubrication
GEOMET® 500 is a self-lubricated basecoat, which allows to obtain a stable and controlled friction coefficient in the
range of 0.12-0.18. This is a simplified solution compared to using a “base coat + top coat” system.

Delta Coatings: (dorken)
High-performance zinc flake coatings offer superior corrosion protection, electrochemical conductivity, and
controlled friction through integrated lubrication. PFAS-free, with excellent adhesion, ductility, and
high-temperature resistance for automotive and industrial components.
Disclaimer: The Delta coating is carried out at Aum Korro Tech (Unit 4 of the Aum Dacro Coatings Group)
Base coat –
The basecoat is the zinc flake coating that is applied directly to the substrate. It determines the corrosion
protection characteristics of the system, with the zinc making it responsible for the cathodic protection. The
application technology may vary, depending on the component.
Basecoat from DÖRKEN
The basecoats from Dörken have a high level of electrochemical conductivity, thanks to the high zinc flake content. The flakes
are each in electrochemical contact to one another. If the coating is damaged, the zinc sacrifices itself, thereby protecting the
steel surface. All Dörken zinc flake basecoats can be combined with the Dörken topcoats
