Bismuth neodecanoate

Bismuth neodecanoate (CAS 34364-26-6) is an organobismuth compound used as a metal catalyst in polyurethane and polymer curing systems.

Where is Bismuth neodecanoate used?

• Polyurethane foam, elastomer and coating formulations: catalyzes the isocyanate-hydroxyl reaction, enabling gel and cure without organotin compounds such as DBTDL
• Sealants and adhesives: controlled open times and through-cure in one- and two-component systems
• Industrial coatings: supports crosslinking of polyurethane and alkyd systems while meeting VOC and heavy metal compliance targets
• Lubricants and metalworking: bismuth-based EP additive precursor and functional component
• It offers a non-tin, non-mercury pathway for catalyzing urethane reactions.

Good to know: Addresses increasingly strict regulatory requirements around heavy metal content in finished products; not to be confused with organotin compounds such as DBTDL.

Commercial specifications

• Liquid, typically in solution form with varying bismuth metal content
• Technical grade; specifications defined by bismuth assay and viscosity parameters relevant to catalyst dosing
• Packaging ranges from drums to IBC containers suited to industrial volumes
