In the dynamic world of silicone chemistry, precision and control are paramount for achieving desired product characteristics. One such compound that plays a crucial role in specialized silicone formulations is Tetramethyldivinyldisiloxane, identified by its CAS number 2627-95-4. This article, brought to you by NINGBO INNO PHARMCHEM CO.,LTD., delves into the significance of this chemical intermediate, particularly its function within two-part Silicone RTV-2 Addition Curing systems.

Tetramethyldivinyldisiloxane is a linear siloxane known for its characteristic colorless to yellowish transparent liquid appearance. Its molecular structure, C8H18OSi2, and a specific gravity of approximately 0.811, make it a distinct compound within the siloxane family. The primary utility of this substance lies in its capacity to act as a linear inhibitor. In the context of Silicone RTV-2 Addition Curing systems, inhibitors are essential for managing the reaction rate.

The effectiveness of Tetramethyldivinyldisiloxane stems from its high vinyl content. This feature allows it to significantly influence the working time, or pot life, of the silicone mixture. By retarding the platinum-catalyzed addition reaction, it provides manufacturers with a crucial window of opportunity to process the material – whether it's for molding, encapsulation, or coating applications. This precise control is invaluable, preventing premature curing and ensuring that the silicone can be applied evenly and without defects. Finding reliable suppliers for such specialized chemicals is key, and NINGBO INNO PHARMCHEM CO.,LTD. is committed to providing high-quality silicone products and intermediates. If you are looking to purchase Tetramethyldivinyldisiloxane, considering its price and availability from reputable manufacturers is a wise first step.

Furthermore, Tetramethyldivinyldisiloxane boasts a boiling point of 139°C, which means it readily volatilizes during the curing process. This characteristic is advantageous as it leaves behind a pure silicone elastomer without residual inhibiting agents, contributing to the final product's integrity and performance. A typical formulation might involve using 0.25 to 0.50 parts by weight of this siloxane per 100 parts of the base polymer that contains the platinum catalyst. This dosage provides effective control without compromising the final cured properties.

The applications for Tetramethyldivinyldisiloxane extend to the production of vinyl end-capped siloxane polymers. These polymers are foundational building blocks for a wide array of silicone-based materials, including silicone rubber, sealants, and coatings, which find extensive use in industries ranging from automotive and electronics to healthcare and consumer goods. Understanding the buy opportunities and the technical specifications, such as minimum purity levels (often 99% or higher), is crucial when sourcing this chemical.
