MIPA-borate

MIPA-borate (CAS 68003-13-4), also marketed under the component name monoisopropanolamine borate, is a reaction product of boric acid and isopropanolamine used as a corrosion inhibitor.

It is a lubricity additive in water-based industrial fluid systems that combines buffering action with metal protection. This makes it a functional component in formulations where pH stability is required.

Its primary use is in metalworking fluids, specifically semisynthetic and synthetic coolants, where it inhibits rust on ferrous substrates. It contributes to film lubricity during machining and grinding.

Aerospace and defense maintenance fluids incorporate this chemical where tight corrosion protection standards apply to aluminum and steel components. It ensures long-term stability for critical parts.

Automotive manufacturing lines use it in cutting and forming fluids to protect tooling and workpieces across high-throughput operations. It is essential for maintaining precision in heavy manufacturing.

It also appears in hydraulic fluid concentrates and rust-preventive coatings where water-dilutable corrosion protection is specified. This versatility makes it a staple in industrial chemical inventories.

The product is supplied as a clear to slightly yellow liquid, typically as a concentrated aqueous solution. Technical grade is the standard commercial specification for most industrial uses.

The product is characterized by active content and a pH profile relevant to fluid formulators. Drum and IBC packaging are the norm for industrial supply volumes to ensure safe transport.
