A zinc rich coating is a coating that contains a high percentage of zinc dust and, when in direct contact with steel, works sacrificially. To protect steel surfaces from corrosion and extend the life of the surface, zinc rich coatings are added. Protexion's zinc rich coating offers superior long-term protection for steel from corrosion and has excellent adhesive and protective properties. For structural steel surfaces, they perform similarly to galvanizing.
To protect steel substrates from corrosion, zinc rich coatings are used by many industries. They are used in applications in highways and infrastructure, manufacturing and automotive. Zinc primers selectively corrode steel when in contact with structural steel, shielding it from damage. For agricultural, coastal, aquatic and freshwater settings, this form of industrial coating is well suited. This may include the use of steel tanks, offshore platforms, barges, refineries, petrochemical and power plants, such as coatings for railcars, pulp and paper mills, and other recommended areas.
Features of Zinc Rich Coating
It is characterized by sufficient resistance to abrasion.
Retains the role of self-preservation of the surface and self-healing during service life.
The interatomic distance in the zinc layer, applied by the bath immersion phase, is close to the interatomic distance in the zinc layer.
UV-stable, with a noble gray hue.
Forming a stable sub dispersion region of Zn-Fe on the metal surface.
It has the property of interlayer diffusion.
It is applied even in winter at a temperature of -35°C.
Zinc Rich Coating is readily compatible with 99% of organic-soluble top coatings. Polyurethane, urethane-acrylic, acrylic, epoxy resin, vinyl chloride, chlorinated rubber, and alkyl coatings are reliably compatible. For ideal compatibility, the holding time after application of Zinc-rich coating composition should be minimum 4-5 hours for the solvent to evaporate and not prevent adhesion in the future. The product can be used as a primer for powder paints.
The following series of six operations comprises the workflow for obtaining an anti corrosion coating based on the zinc-rich coating composition. It is recommended to preserve the anticorrosion coating workflow at an ambient temperature not lower than -35 ° C. The following conditions should be met in order to conduct anti corrosion protection operations in winter:
provide awnings or screening for protection against the elements;
The metal surface temperature should be no less than 3°ะก higher than the dew point temperature.
