DABCO® T 12
- CAS Number
- 77-58-7
- Chemical Name
- Dibutyltin dilaurate
DABCO® T 12 (dibutyltin dilaurate, DBTDL) is a catalyst that enhances the urethane (polyol-isocyanate) reaction in the manufacturing of flexible and rigid polyurethane foams, coatings, adhesives, and sealants. It promotes rapid gel and tack-free times, contributing to improved mechanical properties in molded and slabstock foams.

- Applications
DABCO® T 12 finds greatest use in the manufacture of rigid polyurethane foams. In de- manding applications where amine catalysis alone is inadequate, the extra activity obtained by the synergistic combination of organometallics like DABCO® T 12 with an amine catalyst permits the required rapid catalysis. Examples include high- density structural foam, spray-up wall insulation and rigid boardstock run at high line speeds. Even when used at levels as low as 0.1 phr based on polyol, DABCO® T 12 is especially effective in promoting rapid gel and tack-free times. Tetravalent diorganotins like DABCO® T 12 are known throughout the industry as promoters of the reaction of isocyanates with polyols to form polyurethanes, and of the secondary crosslinking reactions to form allophonate and biuret linkages.; Because of this selectivity for polymerization, DABCO® T 12 is often a benchmark in the catalysis of polyurethane systems including two- component adhesives and moisture-cure coatings, where the oxidative stability of tetravalent tins permits masterbatching of components.; Use-life and retention of catalytic activity of such a masterbatch are dependent upon the presence of amines, moisture and other additives as well as on the storage temperatures. Organotin carboxylates will hydrolyze like any ester, so applications de- manding specific pot lives should be laboratory screened first.
