How does No-Rosion prevent electrolysis and galvanic action between dissimilar metals?
A. Electrolysis occurs when a very small electrical current passes between metals having different electronegativities, such as iron and aluminum. Various contaminants in coolant allow it to function as an electrolyte solution, causing the more electronegative metal (aluminum) to gradually be dissolved. No-Rosion contains a premium ingredient called molybdate, a form of the semi-precious metal molybdenum. Via a process known as electrocrystallization, molybdate forms a molecular-thick film on the surface of aluminum that inhibits the transfer of electrons, thus almost completely preventing damage from electrolysis.

While sacrificial anodes may provide some localized protection within close vicinity of the anode, the protection does not reach all remote areas of the system, whereas the molybdate in No-Rosi
