Description

Tin Tetrabutanolate is a high-purity organotin compound widely used as a catalyst and precursor in advanced material synthesis. Its primary value lies in its exceptional reactivity and selectivity in esterification and transesterification reactions, which are critical for producing high-performance polymers and coatings. This product is essential for R&D laboratories and industrial manufacturers in the polymer, specialty chemical, and pharmaceutical intermediate sectors seeking reliable and efficient catalytic solutions.

Application

• Polymerization Catalyst: A key catalyst for the production of polyesters, polycarbonates, and other condensation polymers.
• Crosslinking Agent: Used in silicone rubber and room-temperature vulcanizing (RTV) silicone formulations to enhance mechanical properties.
• Esterification & Transesterification: Facilitates the synthesis of plasticizers, lubricants, and biodiesel through efficient ester interchange reactions.
• Precursor for Thin Films: Serves as a metal-organic precursor in Chemical Vapor Deposition (CVD) and Atomic Layer Deposition (ALD) for tin oxide coatings.
• Pharmaceutical Intermediates: Employed in the synthesis of specific organotin compounds with potential biological activity.
• Adhesive & Coating Formulations: Acts as a curing agent and adhesion promoter in high-performance industrial coatings and adhesives.

Quality Control

Every batch of Tin Tetrabutanolate is manufactured and tested under a strict quality management system. We provide comprehensive analytical data to ensure the product meets the high standards required for catalytic and synthetic applications. A detailed Certificate of Analysis (COA), including assay, identity confirmation, and impurity profile, is supplied with each shipment and is available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic and highly volatile nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent moisture absorption and decomposition. Keep away from heat, sparks, and open flame.
