What is 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.
Where is Dioctyltin dilaurate used?
- PVC compounding: prevents thermal degradation during high-temperature extrusion and calendering
- Rigid and flexible PVC: stabilizes the polymer matrix during extrusion, calendering and injection molding
- Coatings and adhesives: catalyst for moisture-cure and two-component polyurethane systems
- Sealants and elastomers: supports crosslinking reactions
- Lubricants and metalworking fluids: boundary lubrication contribution in high-load applications
- It reduces discoloration and degradation under processing heat.
Commercial specifications
- Purity typically 95% upward, depending on supplier specification
- Drum and IBC quantities
