Tri-sec-butyl borate

Tri-sec-butyl borate (CAS 22238-17-1) is an organoboron ester used industrially as a catalyst and cross-linking agent.

Where is Tri-sec-butyl borate used?

• Plastics and polymer manufacturing: cross-linking agent for resins and coatings, improving film integrity and adhesion
• Lubricants: additive precursor
• Metalworking fluids: load-bearing and anti-wear performance
• Industrial cleaning: supports surface-active systems requiring controlled hydrolysis
• Specialty chemical synthesis: catalyst in esterification and condensation reactions

Good to know: Moisture-sensitive; handle in sealed containers under inert conditions during storage and transit.

Commercial specifications

• Purity specifications commonly at 95% or higher
• Packaging from small laboratory quantities to drum-scale volumes
