Dibutyltin bis(acetylacetonate)

Dibutyltin bis(acetylacetonate) (CAS 22673-19-4) is an organotin compound used as a catalyst in polymerization and curing reactions across plastics, coatings, and sealant manufacturing.

Its chelated structure provides controlled reactivity, making it suitable for applications where precise cure rate management is a formulation requirement for industrial chemical processes.

In silicone and polyurethane sealant systems, it functions as a condensation cure catalyst, enabling controlled crosslink density in construction and industrial adhesive formulations.

Coating manufacturers use it to accelerate curing in moisture-cure and two-component systems where pot life and through-cure balance are critical for high-performance finishes.

In PVC and polymer stabilization processes, it acts as a processing aid catalyst, supporting thermal stability during compounding and ensuring the integrity of the final plastic product.

Rubber compounders also employ it in elastomer crosslinking where a tin-based catalyst offers selectivity advantages over conventional sulfur or peroxide cure systems in specialized manufacturing.

Dibutyltin bis(acetylacetonate) is supplied as a liquid or viscous solution, typically at concentrations suited for direct addition to formulations during the mixing stage.

Technical grade is the standard commercial offering for industrial catalyst applications. Packaging ranges from small drums to bulk quantities depending on production-scale requirements.
