Methyltris(methylethylketoxime)silane, identified by its CAS number 22984-54-9, is a specialized organosilicon compound that plays a crucial role in the formulation of advanced materials, particularly in the realm of silicone sealants. As a key oxime silane crosslinker, its unique chemical structure and reactivity make it indispensable for achieving specific material properties. For manufacturers and researchers seeking to enhance their product lines, understanding the properties and applications of this compound is paramount. We, as a dedicated supplier, aim to provide clear insights into this versatile chemical.

Understanding the Core Properties of Methyltris(methylethylketoxime)silane

This compound typically presents as a colorless to pale yellow transparent liquid, often with a characteristic odor. Its molecular formula is C13H27N3O3Si, and its molecular weight is approximately 301.46 g/mol. A significant characteristic is its hydrolytic sensitivity, meaning it reacts with moisture. This property is precisely what makes it an effective crosslinker in moisture-curing systems.

Key physical properties include:

  • Boiling Point: Around 110-112°C at 17 mmHg, indicating its moderate volatility.
  • Flash Point: Typically around 90°C, important for safe handling and storage.
  • Purity: Reputable suppliers offer products with purity levels of 70.0% or higher, with many offering 95% or more.

The reaction mechanism involves the release of methyl ethyl ketoxime (MEKO) upon exposure to atmospheric moisture. This neutral release is a significant advantage, allowing the resulting sealants to be applied to a wide range of substrates without causing damage or corrosion, a critical consideration for many industrial applications.

Applications Driving Demand for Methyltris(methylethylketoxime)silane

The primary application for Methyltris(methylethylketoxime)silane is its function as a cross-linking agent in Room Temperature Vulcanized (RTV) silicone rubber and silicone glass glue, particularly those requiring neutral curing. Its ability to create a robust, flexible elastomer network upon reaction with hydroxyl-functionalized silicone polymers is highly valued.

Key application areas include:

  • Silicone Sealants and Adhesives: It serves as the main crosslinker in oxime silicone sealants, either used alone or in combination with other oxime silanes to achieve desired properties such as cure rate, adhesion, and elasticity. These are vital in construction, automotive assembly, and electronics sealing.
  • Protective Coatings: In formulations for protective coatings, it enhances adhesion to various surfaces, improves weather resistance, and increases the overall durability of the coating.
  • Composites and Rubber: It can act as a coupling agent to improve the compatibility and mechanical properties of composites and to enhance the crosslinking density in rubber formulations.
