ABSTRACT:
Zeolites free from heavy metal cations are ion-exchanged with alkaline earth metal cations. The exchanged zeolites provide corrosion resistance to paints for metals, especially ferrous metals, without environmental hazard caused by use of heavy-metal anti-corrosion materials such as lead, chromium, zinc, etc.
