Azoles

Definition

Azoles are organic molecules used specifically to control copper corrosion by chemically bonding to the copper surface. They form hydrophobic films that block water access.

By bonding to copper, azoles create a hydrophobic barrier that suppresses both anodic and cathodic reactions at the surface. They are a film-forming inhibitor that prevents the corrosion circuit from assembling rather than merely slowing it. Azoles complement copper’s natural protective patina.
