Overview
Monoethanolamine borate (CAS 10377-81-8 ), also known as ethanolamine borate, is a boron-nitrogen compound used industrially as a corrosion inhibitor, pH buffer, and chelating agent.
It combines the functional properties of both ethanolamine and borate chemistry, making it effective across metal-contact and aqueous formulation environments.
In metalworking fluids and cutting oils, it inhibits ferrous and non-ferrous metal corrosion while maintaining alkaline pH stability over extended service life.
Coating formulations incorporate it as a buffering agent to control cure conditions and improve adhesion to metal substrates during the application process.
Water treatment programs use it to sequester hardness ions and prevent scale deposition in recirculating systems. It is highly effective in these industrial environments.
In adhesives and sealants, it functions as a crosslinking aid and pH stabilizer, particularly in systems sensitive to metal ion contamination or fluctuations.
Monoethanolamine borate is typically supplied as a liquid solution, with concentration varying by application requirement and supplier specification for the end user.
It is generally available in technical grade for industrial applications including metalworking, coatings, and water treatment. Bulk liquid supply is the standard format.
