Advantages of Zinc Flake Coatings;
Unlike paints where there is a risk of subsurface corrosion creep, this avoids the sacrificial effect of zinc. In NSST, zinc flake coatings show better protection than a typical galvanic zinc coating that usually achieves only 96 to 200 hours in testing (usually working according to DIN EN ISO 9227).
When using cataphoretic paint, there is no cathodic cornice protection when the paint layer is damaged. You will notice that red rust occurs in gaps and scratches that cause the layer to stick and swell / chip.
Zinc or zinc alloy coated coating layers do not create any residue inside the tubes. Coating can cause hydrogen embrittlement on high strength steel materials
Hot-dip galvanizing leads to high weights with risk of solder brittleness / brittleness. Due to high processing temperatures, parts can deform and the temperature can reduce the hardness of the steel. Films in punched holes and holes require extensive rework and the base material can be released
Zinc-plated parts have no protection on the cut edge.
Zinc grain coatings have excellent corrosion protection as there is no risk or hydrogen embrittlement. It is also resistant to temperature extremes and has good frictional properties (on bolts and nuts).
The zinc flake coating is also environmentally friendly and there is no risk of any hydrogen embrittlement for high strength fasteners. As a result, zinc flake coating can be used on a wide variety of parts and offers some great advantages.
