Product Application of Dibutyltin Dilaurate CAS#77-58-7
Dibutyltin Dilaurate (CAS 77-58-7) is a high-performance organotin catalyst widely used in multiple applications. In polyurethane foaming, it helps control gel time to ≤90 seconds (ASTM D7487) in flexible and molded foams. For silicone curing, it acts as a condensation catalyst in RTV sealants, contributing to performance such as hardness (ISO 7619). In coatings, it functions as a curing accelerator for alkyd resins, improving adhesion properties (ISO 3251). Additionally, it is used in adhesive formulations as a fast-curing promoter for structural bonding (EN 1465). The product is exempt under REACH Annex XIV, and technical guidance is available for various applications.
