Recharging Zinga
Another of Zinga's unique characteristics is its ability to re-liquidise when a new coat of Zinga is applied onto an existing Zinga layer to form a single homogenous layer. This ensures a massive cost saving in on-going maintenance, because the old Zinga layer does not have to be removed before re-coating with a new Zinga layer. This also means that once the initial abrasive blasting has been completed, the steel's surface will never have to be blasted again.
The following microscopic photos demonstrate the total integration of multiple layers of Zinga:
First Coat
A thin film of gold dust was applied on top of the first coating of Zinga.
Second Coat
Seven days later a second coating of Zinga was applied on top of the gold dust. It can be clearly seen that the gold dust has mixed completely within the two Zinga layers.

The same test was done with a typical "zinc-rich" paint. The gold film remains intact between the two coats demonstrating that they remain as separate layers.
What Is Zinga?
Zinga was originally invented in Ghent University, Belgium, in the 1970's and has since been used in a wide variety of projects throughout the world...
HOW ZINGA WORKS
Cathodic protection, or active protection, arises from the zinc (the anode) sacrificing itself in favour of the base metal (the cathode) with the resulting flow of electrons preventing corrosion's...
