Chromium formate

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

Where is Chromium formate used?

• Leather tanning: masking agent and auxiliary tanning salt
• Textile dyeing: mordant and fixative that enhances dye adhesion on wool and protein fibers
• Metalworking and surface treatment: passivation baths and corrosion-inhibiting coatings with controlled chromium deposition
• Mining and hydrometallurgy: catalyst component or complexing agent in selective metal recovery circuits
• In industrial process chemistry it functions as a surface modifier, corrosion inhibitor, and catalyst precursor.

Commercial specifications

• Concentration and purity specifications vary by end-use sector
• Buyers for specialty applications should confirm chromium content, pH range, and solution stability with the supplier
