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. It delivers controlled reactivity in polymer curing and surface treatment processes where precise boron delivery is required.

In plastics and polymer manufacturing, it functions as a cross-linking agent for resins and coatings, improving film integrity and adhesion performance. Lubricant formulators incorporate it as an additive precursor.

Boron-containing compounds contribute to load-bearing and anti-wear performance in metalworking fluids. In industrial cleaning formulations, it supports surface-active systems that require controlled hydrolysis behavior.

This allows for the release of active boron species during application. It also serves as a catalyst in esterification and condensation reactions, relevant to specialty chemical synthesis feeding into polymer supply chains.

Tri-sec-butyl borate is supplied as a liquid, typically handled in sealed containers under inert conditions. This is necessary due to moisture sensitivity during storage and transit to ensure product stability.

Technical grade is the standard commercial offering, with purity specifications commonly at 95% or higher. Packaging ranges from small laboratory quantities to drum-scale volumes for industrial procurement.
