Used primarily as a catalyst in the production of polyurethanes and alkyd resins, enabling faster curing and improved film formation in coatings and adhesives. Also employed in sol-gel processes for synthesizing antimony-containing oxide materials, which find use in flame retardants and transparent conductive coatings. Its reactivity with moisture makes it suitable for chemical vapor deposition (CVD) applications in electronics and optical films. Additionally, it acts as a stabilizer and cross-linking agent in certain polymer systems, enhancing thermal and mechanical properties.
