Description

Tin (II) Octoate is a versatile organotin compound widely recognized as a highly effective catalyst in polyurethane chemistry. Its primary value lies in accelerating the reaction between isocyanates and polyols, enabling efficient production of flexible and rigid foams, elastomers, and coatings. This catalyst is essential for manufacturers in the polyurethane, silicone, and specialty polymer industries seeking to optimize cure times and final product properties.

Application

• Polyurethane Foam Production: A key catalyst for promoting the gelling (urethane) reaction in the manufacture of flexible slabstock, molded, and rigid polyurethane foams.
• Polyurethane Elastomers & Coatings: Used in casting, spray, and two-component coating systems to control pot life and cure profile for durable finishes, adhesives, and seals.
• Silicone Curing: Acts as a catalyst in condensation-cure silicone systems, such as RTV (Room Temperature Vulcanizing) sealants and adhesives.
• Esterification & Transesterification Reactions: Serves as a catalyst in organic synthesis for producing plasticizers, lubricants, and biodiesel.
• Specialty Polymer Synthesis: Employed in the production of polyesters and other polymers where controlled reaction kinetics are critical.

Quality Control

Our Tin (II) Octoate is manufactured under strict quality protocols to ensure batch-to-batch consistency and performance reliability. Each lot is analyzed to confirm critical parameters such as tin content, acidity, and specific gravity. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with every shipment to support your quality assurance and regulatory compliance needs.

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 product is easily oxidized (store under inert atmosphere) and highly volatile. Keep away from heat, sparks, and open flame. Containers should be kept tightly sealed when not in use to minimize moisture absorption and prevent evaporation.
