Di-n-butyldi-n-butoxytin is primarily used as a catalyst in the production of polyurethanes, particularly in flexible and impact-resistant products such as foams, coatings, and adhesives. It accelerates the urethane bond formation between isocyanates and alcohols, enabling faster and more efficient manufacturing processes. Additionally, it serves as a catalyst in silicone curing reactions and is employed in the synthesis of specialty polymers requiring high thermal stability. This compound is also effective in solvent-free coating systems, where it prevents air bubble formation during reactions and offers excellent compatibility with various precursors. While it can contribute to stabilization in certain polymer applications, its main role is catalytic.
