5-Aminotetrazole（5-AT）

Performance & Application

Specially used as a corrosion inhibitor for metal copper and

copper alloys in the semiconductor, microelectronics, display

and printed circuit board industries, and also has corrosion

inhibition effect on ferrous metals. Copper corrosion inhibitor 5-

AT is adsorbed on the surface of copper to form a thin film,

thereby protecting and controlling the etching and corrosion of

copper surface treatment process.
