Four formulations were suggested to reduce the corrosion rate when added to both fresh and salt water. Formulated according to VCI technology, these products include inhibitors for multi-metal protection in liquid, vapor and interface liquid/vapor phase.

The performance of the products was evaluated at different temperatures in the immersion test and electrochemical techniques.

The synergistic effect of the components in formulations was studied using infra-red spectroscopy.

The protection ability vs. concentration was studied for the additive for an open loop cooling system (OCA).
