Dioctyltin bis(acetylacetonate)

Dioctyltin bis(acetylacetonate) (CAS 54068-28-9), also referenced commercially as dioctyltin diketanoate, is an organotin compound used as a catalyst in polymer curing and crosslinking systems.

Where is Dioctyltin bis(acetylacetonate) used?

• Silicone rubber: catalyzes room-temperature and heat-cure crosslinking
• Polyurethane: regulates gel time and cure profile in cast elastomers and sealants
• PVC stabilization research and specialty polymer compounding: processing catalyst where thermal stability during melt processing is a formulation requirement
• Rubber: assessed for crosslink density management in specialty elastomer applications
• It drives controlled reaction rates in silicone and polyurethane processing without aggressive activation conditions.

Good to know: Preferred where low-toxicity organotin alternatives to dibutyltin systems are specified.

Commercial specifications

• High active-content concentrations suited for direct addition during mixing
• Packaging from small laboratory quantities to drum-scale supply
