SILICALLOY is a totally chrome-free treatment that gives galvanized surfaces good corrosion resistance and offers excellent adherence for subsequent coatings.
The original problem concerned the surface conversion of galvanized steel by chromium VI, which is toxic and carcinogenic.
The project has produced the first chromation replacement treatment to combine effectiveness and sustainable development through the use of proven non-toxic silica nanoparticles.
This treatment, dubbed “Silicalloy”, has been validated in the laboratory, on a pilot line, and on an industrial line for passivation from the galvanized to the tempered product.
It is also very promising for other processes and surfaces, such as reflector coatings for lights and the passivation of aluminum.
