Zinc flake has gained good prominence in the market that require a relatively inexpensive, thin, highly corrosion resistant coating . These are several brand names such as Geomet, Dacroment, Dacrotized, Magni, Delta, etc. The specific brand is not always easily in a country, but each of these coatings have one thing in common: a thin, tailor-made coating with excellent corrosion resistance.
To specify the coating independent of brand, the IDIN EN ISO 10683 standard. The standards specify xcavtly the salt spray hours resistance rquired as well as the properties required of the coating. For more info, see below.
As with other zinc based coatings, the corrosion resiatance is dependent on the thickness of the coating. Approximate salt spray hours to red rust is given below:
- 6 – 8 µm: 720 hrs
- 8 – 12 µm: 1000 hrs
- 15 – 20 ↨0m: 1500 hrs
