Chromium formate

Chromium formate (CAS 27115-36-2), also known as chromic formate, is an organochromium salt used across metal treatment, textile processing, and leather manufacturing.

It functions as a surface modifier, corrosion inhibitor, and catalyst precursor in industrial process chemistry. In leather tanning, it acts as a masking agent and auxiliary tanning salt.

This chemical improves chrome uptake and produces uniform, well-penetrated leathers. Textile dyeing operations use it as a mordant and fixative to enhance dye adhesion on wool and other protein fibers.

In metalworking and surface treatment, it is applied in passivation baths and corrosion-inhibiting coatings where controlled chromium deposition is required for industrial protection.

Mining and hydrometallurgical processes also employ it as a catalyst component or complexing agent in selective metal recovery circuits to ensure efficient chemical reactions.

Chromium formate is typically supplied as an aqueous solution or crystalline solid, with concentration and purity specifications varying by end-use sector and specific application.

Technical grade is the most common commercial form, with specifications aligned to industrial tanning and metalworking requirements for large-scale manufacturing and processing.

Buyers sourcing for specialty applications should confirm chromium content, pH range, and solution stability with the supplier prior to procurement to ensure compatibility with systems.
