Description
Dibutyltin dilaurate (DBTDL, CAS 77-58-7) is an organotin compound supplied as a yellow oily liquid, also known under trade names Butynorate and Stabilizer D 22. It carries no E-code designation and is classified under HS code 29319090 within the Catalysts and Catalyst Precursors category.
In polyurethane foam and elastomer production, DBTDL accelerates the urethane-forming reaction between isocyanates and polyols by coordinating with the isocyanate group, controlling gel time and cell structure. It also functions as a heat stabilizer in PVC compounding, where it interrupts dehydrochlorination chain reactions at processing temperatures to prevent discoloration and degradation.
DBTDL is available in standard industrial grades and supplied in drum and IBC formats. It falls under REACH regulation (EC 1907/2006) and requires an up-to-date Safety Data Sheet for EU procurement. Buyers should confirm supplier REACH registration status and review current SVHC candidate list obligations before sourcing.
