Dioctyltin dilaurate

Dioctyltin dilaurate (CAS 3648-18-8 ) is an organotin compound used as a heat and light stabilizer in PVC processing and related polymer systems. It prevents thermal degradation during high-temperature compounding and extrusion, extending the service life of finished plastic articles. In rigid and flexible PVC formulations, it stabilizes the polymer matrix during extrusion, calendering, and injection molding. This reduces discoloration and degradation under processing heat, ensuring the integrity of the final material. Coating and adhesive formulators use it as a catalyst for moisture-cure and two-component polyurethane systems. It allows for precise control over the cure rate and final film properties in various industrial applications. In sealants and elastomers, it supports crosslinking reactions where consistent cure speed is critical to production throughput. This reliability is essential for maintaining efficiency in high-volume manufacturing environments. Lubricant and metalworking fluid manufacturers incorporate it for its boundary lubrication contribution in high-load applications. This versatility makes it a valuable additive across multiple chemical sectors and industrial processes. Dioctyltin dilaurate is supplied as a pale yellow to amber liquid. Technical grade is the standard commercial form, with purity levels typically ranging from 95% upward depending on the specific supplier specification. It is available in drum and IBC quantities suited to industrial-scale consumption in plastics compounding and coating production. Proper handling and storage are required to maintain the chemical stability of the product over time. Contact us for supply of Dioctyltin dilaurate Request Quote
