Passivex C

Product code RXSOL-38-2401-220

Gentle passivation liquid for safe metal passivation without toxic fuming

Description

RXSOL Passivex C is a concentrated, water-based citric acid passivation liquid designed for the chemical passivation of stainless-steel surfaces following fabrication, welding, machining, grinding, pickling or cleaning.

The product removes surface contamination and assists in the removal of free iron and other iron-containing residues from stainless-steel surfaces, promoting the formation and restoration of a stable chromium-rich passive oxide layer.

Unlike conventional nitric-acid passivation products, RXSOL Passivex C uses citric acid technology and is suitable for applications where a nitric-free passivation process is preferred.

ASTM A967/A967M specifically recognizes Passivex C immersion treatments as chemical passivation treatments for stainless-steel parts.
