Inorganic Zinc
Inorganic Zinc flake coatings are non-electrolytically applied coatings, which provide excellent corrosion and weathering protection, as well as very good resistance to media and solvents. This technology is based on a mix of zinc and aluminium flakes, which are bonded together by an inorganic matrix. Such coatings can be successfully used for the protection of high-strength metal parts, preventing damage caused by hydrogen embrittlement.
SERVICE INFORMATION
Zinc flake coatings represent an environmental-friendly alternative to the traditional coatings and are mainly used as cathodic protective layers in the automotive and construction industries. They are well suited for protecting both large and small parts, having either simple or complex geometry. In combination with post-treated thin organic or inorganic coatings, these can also provide color, chemical resistance, low electrical conductivity, and bolting properties.
Inorganic Zinc Coating Different types
We use two zinc flake-based products ranges developed by NOF Metal Coatings Group: Dacromet® and Geomet®:
