Uysal Makina explains that GEOMET® coating is suitable for all kinds of fixings and metal parts and provides high corrosion resistance and controlled friction. It is preferred by the automotive and heavy construction industries because it is water-based and, therefore, more environmentally friendly. It is non-electrolytic, being applied by dipping, rotating or spraying methods. The coating, which can be applied as a thin layer, is hexavalent chromium and other heavy metals free but still takes full advantage of the anti-corrosion properties of zinc. The coating process does not introduce the risk of hydrogen embrittlement making it particularly suitable for high-tensile products. The coating makes repeated fastening and disassembling easy.
