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®:

  • GEOMET® is a water-based and completely chrome-free chemical coating and capable that is used to protect a wide variety of metallic surfaces

  • DACROMET® products is a worldwide recognized standard widely used in non-automotive sectors such as rail, wind power and public works. It is particularly suited for thin layer thicknesses

    Inorganic Zinc Advantages

    We use such methods as dip-spinning and spraying to apply extremely corrosion-resistant zinc flake coatings. These technologies enable us to guarantee high performing thin layer anti-corrosion coatings for metallic parts.:

  • Long-term corrosion protection

  • non-electrolytic process

  • Very thin layer thicknesses

  • Integrated lubricant additives

  • Water-based chemistry

  • Metallic silver appearance

  • Stable friction coefficients

  • Resistance to high treatment temperatures and chemicals

  • Protection against contact corrosion
