Zinc flake coatings are non-electrolytically applied coatings that offer very good corrosion protection through a so-called cathodic protection.
The coatings consist of a mixture of zinc and aluminum flakes that are bonded through an inorganic matrix.
Layer thickness information refers to average values acc. to DIN EN ISO 4042 and DIN EN ISO 10683.
Grade A (2-layer coating)
> 5 – 8 µm
Grade B (3-layer coating)
> 8 – 12 µm
Corrosion resistance acc. to ISO 9227 NSS:
Depending on layer structure, geometry and application technology,
up to 1000h without FeK
Temperature resistance / baking temperature
Up to 250°C / approx. 300°C
