Description

2-Ethylhexyl 5-Butyl-12-Ethyl-5-[[3-[(2-Ethylhexyl)Oxy]-3-Oxopropyl]Thio]-9-Oxo-10-Oxa-4,6-Dithia-5-Stannahexadecanoate is a specialized organotin compound with the CAS number 61241-05-2, designed for high-performance applications requiring thermal and UV stabilization. This chemical is valued for its ability to impart exceptional durability and longevity to polymer systems under demanding environmental conditions. It is primarily sought by manufacturers in the plastics, coatings, and specialty chemical industries for formulating advanced stabilizer packages.

Application

• Polymer Stabilizer: Acts as a highly effective heat stabilizer and light stabilizer in PVC (polyvinyl chloride) and other halogenated polymers to prevent degradation during processing and end-use.
• Plastic Additive: Used in the formulation of rigid and flexible PVC products, including pipes, fittings, profiles, cables, and films, to enhance weatherability and service life.
• Coatings Industry: Incorporated into coating systems to provide UV protection and prevent chalking, cracking, and loss of gloss in exterior applications.
• Lubricant Additive: Serves as a multifunctional additive in synthetic lubricants and greases, offering anti-wear and extreme pressure properties.
• Silicone Cross-linking Agent: Functions as a catalyst or co-agent in the curing and cross-linking of silicone polymers and room-temperature vulcanizing (RTV) silicones.
• Specialty Synthesis: Employed as a key intermediate or catalyst in organic synthesis for the production of fine chemicals and pharmaceuticals.
