What is Dibutyltin diacetate?
Dibutyltin diacetate (CAS 1067-33-0), commonly abbreviated as DBTDA, is an organotin compound used as a catalyst for curing and cross-linking reactions in polymer and sealant manufacturing.
Where is Dibutyltin diacetate used?
- Silicone sealants and elastomers: catalyzes room-temperature vulcanization in one- and two-component systems for construction, automotive and electronics assembly
- Polyurethane coatings and adhesives: controls gel time and cross-link density
- PVC compounding: stabilizer catalyst supporting thermal stability during processing
- It accelerates condensation and addition reactions that would otherwise need elevated temperatures or longer processing times.
Commercial specifications
- Packaging from drums to intermediate bulk containers (IBCs)
