New composite coating protects from corrosion at high mechanical stress

Researchers at the Leibniz Institute for New Materials have developed a composite coating material which prevents metal corrosion in an environmentally friendly way, even under extreme conditions. It can be used wherever metals are exposed to severe weather conditions, aggressive gases, media containing salt, heavy wear or high pressures.

This patented composite exhibits its action by spray application. The key is the structuring of this layer—the protective particles arrange themselves like roof tiles. As in a wall, several layers of particles are placed on top of each other in an offset arrangement; the result is a self-organized, highly structured barrier.

—Carsten Becker-Willinger, Head of the Nanomers Program Division

The protective layer is just a few micrometers thick and prevents penetration by gases and electrolytes. It provides protection against corrosion caused by aggressive aqueous solutions, including for example salt solutions such as salt spray on roads and seawater, or aqueous acids such as acid rain. The protective layer is an effective barrier, even against corrosive gases or under pressure.


After thermal curing, the composite adheres to the metal substrate, is abrasion-stable and impact-resistant. As a result, it can withstand high mechanical stress.

The coating passes the falling ball test with a steel hemispherical ball weighing 1.5 kg from a height of one meter without chipping or breaking and exhibits only slight deformation, which means that the new material can be used even in the presence of sand or mineral dust without wear and tear.

The composite can be applied by spraying or other commonly used wet chemistry processes and cures at 150-200 °C. It is suitable for steels, metal alloys and metals such as aluminum, magnesium and copper, and can be used to coat any shape of plates, pipes, gear wheels, tools or machine parts. The specially formulated mixture contains a solvent, a binder and nanoscale and platelet-like particles; it does not contain chromium VI or other heavy metals.



Very interesting for all vehicles used in snowy-icy places where salts are regularly used.

Hope that all manufacturers will make use of this process soon.


We were searching for a name which people will remember to call our new miracle coating.

So we selected a new unused name. We call it 'Paint'.

Nobody will buy an anti-rust 'paint' option to reduce or eliminate rust. Sounds too much like something that should have been done 100+ years ago.

A low cost option called: Rustban, rustoban, life-extender, 20-year protector, etc may work?
