BLACK ARMOUR® Metal Treatment

The BLACK ARMOUR® metal protection process chemically bonds with metal to form a protective skin that is impervious to water and anti-icing chemicals. BLACK ARMOUR® is paint compatible without pre-sanding. If scratched, BLACK ARMOUR® inhibits the spread of creep corrosion.

This eco-friendly metal treatment provides remarkable protection without the added weight and cost of galvanization.

· Guards against environmental factors, e.g. moisture, stone chipping and salt
· No rust penetration
· Long-lasting and reliable retention of value
