Monoethanolammonium borate

Monoethanolammonium borate (CAS 26038-87-9) is a boron-based amine salt combining ethanolamine and boric acid in a 1:1 ratio. It functions as a corrosion inhibitor and pH buffer in water-based industrial systems.

Both the amine and borate components contribute to metal protection and formulation stability. In metalworking fluids, it protects ferrous and non-ferrous metal surfaces from corrosion while maintaining the alkaline pH range.

This stability is required for cutting and grinding operations. Water treatment formulations use it to buffer system pH and inhibit corrosion in recirculating cooling and process water circuits.

In waterborne coatings and primers, it supports flash rust inhibition on metal substrates during application and drying. Adhesive and sealant systems benefit from its buffering capacity during the manufacturing process.

Controlled pH stability influences cure behavior and substrate compatibility. Monoethanolammonium borate is typically supplied as an aqueous solution, with concentration varying by producer and application requirement.

Technical grade is the standard commercial offering for industrial lubricant, coating, and water treatment uses. Buyers should confirm active content and pH specification when evaluating lots.

Boron concentration is also a key metric for formulation-critical applications. This chemical ensures long-term performance and protection in diverse industrial environments and specialized chemical formulations.
