Descripción
Chem-Crest ProPass is a phosphate-free citric passivation concentrate and deoxidizer cleaner designed to remove surface contamination, increase corrosion resistance, remove discoloration, tarnishes, scales and oxides. It is an alternative for nitric acid passivation, and passes citric acid passivation evaluations such as ASTM A967.

Chem-Crest ProPass removes light oils, light scales and oxides, and general contaminants from the surfaces of parts. To extend the life of the bath, it is recommended to ultrasonically clean before passivation.
