Dibutyltin dichloride

Dibutyltin dichloride (CAS 683-18-1), also known as dibutyltin chloride, is an organotin compound used industrially as a catalyst and stabilizer precursor.

Where is Dibutyltin dichloride used?

• Reactive intermediate in the synthesis of other dibutyltin derivatives
• Direct catalyst in condensation and polymerization processes
• PVC and polymer processing: precursor to heat stabilizer packages that prevent thermal degradation during compounding and extrusion
• Coatings: catalyst in moisture-cure urethane and silicone systems, accelerating crosslinking at ambient conditions
• Adhesives and sealants: promotes cure in tin-catalyzed RTV silicone formulations
• In specialty ink and lacquer systems it initiates controlled polymerization.

Commercial specifications

• Purity typically 95% or higher, depending on supplier specification
• Drum and bulk quantities for industrial procurement
