Dibutyltin Bis(Acetylacetonate)

PowerCat™ DBTK is a high-activity organotin catalyst based on dibutyltin bis(acetylacetonate). It is widely used as a catalyst for moisture-curing silane-terminated polymers (STP/MS Polymers), RTV silicone systems, silane condensation reactions and polyurethane applications.


Compared with conventional dibutyltin dilaurate (DBTDL), PowerCat™ DBTK provides faster curing performance, improved storage stability and lower odor, making it particularly suitable for one-component moisture-curing sealants and adhesives.


PowerCat™ DBTK is compatible with most organic solvents but is sensitive to moisture and should be handled under dry conditions.

Application


PowerCat™ DBTK is a high-activity organotin catalyst recommended for moisture-curing silane-terminated polymers (STP/MS Polymers), RTV silicone sealants and rubber, silane condensation reactions, polyurethane coatings, adhesives and sealants, as well as other moisture-curing polymer systems.


PowerCat™ DBTK provides fast curing performance, excellent storage stability and low odor. It is particularly suitable for one-component moisture-curing systems requiring rapid cure development and efficient silane crosslinking. The catalyst exhibits good compatibility with common organic solvents and can be used in both one-component and two-component formulations. Compared with conventional dibutyltin dilaurate (DBTDL), PowerCat™ DBTK offers improved curing efficiency and enhanced formulation stability.
