Methyltrimethoxysilane IOTA-20: Core Crosslinking and Coupling Agent for Silicon-Based Materials
In the fields of silicone rubber, silicone resin, and glass fiber modification, Methyltrimethoxysilane IOTA-20 has become a key additive linking the preparation of various silicon-based materials, thanks to its high-purity quality and precise chemical reactivity. Its clear chemical identification—English name Methyltrimethoxysilane, CAS No.: 1185-55-3, and structural formula CH₃Si(OCH₃)₃ (molecular weight 136.2)—demonstrates the product’s standardized properties, providing a reliable basis for precise applications across industries.
Stable and excellent physicochemical properties form the foundation for efficient application. IOTA-20 appears as a colorless, transparent liquid with a pure, impurity-free appearance, and is fully miscible with alcohols, ketones, benzene, and various other organic solvents, allowing easy integration into diverse production systems. Authoritative testing shows its key indicators are precise and controllable: at 20°C, the density remains stable at 0.95 ± 0.02 g/ml, the refractive index is 1.3690 ± 0.0020, and its physical properties are highly uniform; it has a boiling point of 102°C/760 mmHg and a flash point of 5°C, providing precise thermodynamic data for temperature control during production. Notably, its ability to crosslink upon contact with water and generate methanol forms the core chemical basis for its crosslinking function.
The high purity supports multiple core applications, establishing the product’s irreplaceable industrial value. With a main content of ≥99.0%, IOTA-20 ensures high reaction efficiency and product stability. As a silicone rubber crosslinking agent, it precisely initiates crosslinking reactions, significantly improving the mechanical properties and environmental stability of silicone rubber; as a glass fiber coupling agent, it effectively enhances the adhesion between glass fibers and resin matrices, improving the overall strength and durability of composites; meanwhile, it serves as a high-quality raw material for the preparation of silicone resins, providing solid support for the research and production of specialty silicone resins.
From storage to packaging, the product design fully accommodates industrial production needs. It should be stored in sealed containers in a cool, dry, and dark place. Its non-corrosive nature allows it to be transported as a general chemical, reducing logistics costs and risks. Packaging options include 25 kg, 190 kg, and 200 kg, covering plastic drums and inner-plastic/outer-iron drums, flexibly meeting the varying needs of laboratory trials, pilot-scale, and large-scale industrial production. Whether for upgrading silicone rubber products, modifying glass fiber composites, or developing silicone resins, choosing Methyltrimethoxysilane IOTA-20 means selecting precise and controllable reactions, stable and reliable product quality, and efficient production processes, injecting key momentum into the high-quality development of the silicon-based materials industry.
