Description

Decyl 4-[[2-(Decyloxy)-2-Oxoethyl]Thio]-4-Octyl-7-Oxo-8-Oxa-3,5-Dithia-4-Stannaoctadecanoate is a high-purity organotin compound, specifically a dialkyltin carboxylate derivative, valued for its role as a highly effective catalyst and stabilizer in polymer chemistry. Its complex structure provides excellent thermal stability and catalytic activity, making it a critical component for manufacturers requiring precise reaction control. This chemical is essential for producers of polyurethane foams, PVC stabilizers, and silicone elastomers who demand consistent performance and supply chain reliability.

Application

• Polyurethane Catalyst: Acts as a highly efficient catalyst for the production of flexible and rigid polyurethane foams, promoting consistent cell structure and curing.
• PVC Heat Stabilizer: Serves as a critical component in non-toxic, calcium-based PVC stabilizer systems for pipes, profiles, and transparent films.
• Silicone Cross-Linking Agent: Used as a catalyst in the curing (cross-linking) of room-temperature vulcanizing (RTV) silicone rubbers and sealants.
• Esterification & Transesterification Catalyst: Facilitates esterification and transesterification reactions in the synthesis of plasticizers, lubricants, and biodiesel.
• Polymer Additive: Functions as a stabilizer and catalyst in various specialty polymer formulations to enhance processing and final product properties.
• Adhesive & Coating Formulations: Incorporated into high-performance adhesive and coating systems to improve cure rates and durability.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is easily oxidized and should be kept under an inert atmosphere (e.g., nitrogen) after opening to prevent degradation. Keep away from strong oxidizing agents, strong acids, and strong bases.
