Dibutyltin dichloride is widely used as a catalyst in the production of polyurethane foams and coatings. It accelerates the reaction between polyols and isocyanates, ensuring efficient and uniform foam formation. In the manufacturing of PVC (polyvinyl chloride), it acts as a stabilizer, preventing degradation during processing and enhancing the material's durability. Additionally, it is employed in the synthesis of organotin compounds, which are utilized in various industrial applications, including antifouling agents for marine paints. Its catalytic properties also make it valuable in esterification and transesterification reactions, particularly in the production of plasticizers and lubricants.
