Dacromet-coating

Dacromet is an inorganic, strongly adhesive coating consisting of zinc and aluminium in a chromate compound. This type of coating offers a high degree of protection against corrosion. It also provides a high heat resistance and a low coefficient of frictionwith no risk of hydrogen embrittlement.

The Dacromet coating is applied by dip-centrifuging in an aqueous solution of zinc chromate(with a low aluminium content), dried, and subsequently baked. Individual springs with an outside diameter < 40 mm can sometimes stick together.

Dacromet-coated springs are primarily used for outdoor applications requiring a high degree of corrosion protection.
