What is Dibutyltin dilaurate?
Dibutyltin dilaurate (CAS 77-58-7), abbreviated DBTL, is an organotin compound used industrially as a catalyst and stabilizer. Also marketed as Davainex and Tinostat.
Where is Dibutyltin dilaurate used?
- Polyurethane manufacturing: catalyzes the isocyanate-hydroxyl reaction
- Flexible and rigid foam production: controls foam rise and gel times
- Silicone sealant and RTV formulations: consistent cure rates at room temperature
- Construction and automotive sealants: standard catalyst choice
- PVC compounding: heat stabilizer against degradation during extrusion and calendering of flexible profiles
- Films and wire coatings
- Lubricant and metalworking fluids: antioxidant additive that extends service life under high-temperature conditions
- It accelerates curing and crosslinking reactions in polymer systems while providing thermal and oxidative stabilization during processing.
Commercial specifications
- Technical grade, purity typically 95% or higher
- Drum and IBC quantities
- Specifications aligned to industrial polymer and coatings applications, not food or pharmaceutical use
