Cyclohexylamine benzoate

Cyclohexylamine benzoate (CAS 3129-92-8), also known as cyclohexylammonium benzoate, is a vapor-phase corrosion inhibitor used to protect ferrous and non-ferrous metals during storage, transit, and processing. It functions by releasing inhibiting vapors that form a protective molecular layer on metal surfaces without direct contact. Its primary use is in volatile corrosion inhibitor packaging such as impregnated films and papers.

These foam emitters are designed to protect finished metal components, machined parts, and tooling during long-term storage or export shipping. In metalworking fluids, it is incorporated to extend the protection window. This is particularly effective for steel and cast iron parts between production stages. Coatings formulators use it as an additive in primers and temporary protective coatings applied to automotive components.

It is also utilized for industrial equipment. Adhesive and sealant manufacturers targeting metal-bonding applications evaluate it for its ability to condition metal surfaces prior to the curing process. The product is supplied as a white crystalline powder. It is available in technical grade, which is the standard specification for industrial corrosion inhibition applications across various sectors.

Packaging typically ranges from kilogram-scale bags to bulk quantities suitable for industrial compounding. This ensures flexibility for both small-scale testing and large-scale manufacturing requirements.
