The use of ion-exchange bentonites in anticorrosive paints

What is it about?

Bentonite has the ability of exchange its Na-ion that is naturally abundant in its structure. Ions that have good behavior in anticorrosive performance on cold rolled steel substrates such as (Zn, Sr, and Zn-Sr) were exchanged and their effect in protecting steel was studied using accelerated laboratory test and electrochemical impedance spectroscopy. Their behavior was better than original bentonite, Sr was better than Zn and both were better than Sr-Zn-bentonite.

Why is it important?

IEBs can be considered as a safe and efficient alternative to traditional hazardous pigments in protecting steel surfaces.
