ZMSpin - disruptive anticorrosion coating 29 October 2021

CNP Myszkow has developed a new coating, ZMspin, based on an alloy of magnesium, aluminium, and zinc, applied in the process of hot dip galvanising with centrifugation. The coating is ideal for fasteners such as screws, nuts, washers, pins, and others.

CNP says its ZMspin coating gives spectacular results in salt chamber testing, where the tested items do not show traces of corrosion even after 3,000 hours. The technological process does not use acids to activate the surface, and thus the parts have no possibility of hydrogen embrittlement. Additionally, low bath temperature is used in the ZMspin coating galvanising process. This provides additional assurance that components subjected to the ZMspin galvanising process will not be at risk of hydrogen embrittlement. The technological process generates much less waste concerning the classic hot dip galvanising, which allows reducing the negative impact on the environment. 

ZMspin coating allows reducing maintenance costs of steel structures. Thanks to its properties, potential damage to the anti-corrosion coating during assembly is reduced to a minimum. ZMspin can be successfully used in applications currently requiring DUPLEX coating.

ZMspin coating applied to fasteners allows unifying anticorrosion protection used for automotive parts, where currently sheets with MgAlZn coating are widely used, thus providing an alternative to the flake coatings of Zinc.
