Description

Silane, Trimethoxy(1-Methylethyl)- CAS NO 14346-37-3 is a specialized organosilicon compound, specifically an isopropyl-substituted alkoxysilane. This chemical is valued for its dual functionality, serving as both a coupling agent and a surface modifier in advanced material synthesis. It is primarily sought by manufacturers in the silicone polymer, adhesive, and coatings industries who require precise control over material interfaces and enhanced composite performance.

Application

• Crosslinking Agent: Used in the production of moisture-curable silicone polymers and resins, where it contributes to network formation and final material properties.
• Surface Priming & Modification: Acts as an adhesion promoter and surface treatment for inorganic materials like glass, minerals, and metals to improve bonding with organic polymers.
• Composite Materials: Enhances the dispersion and interfacial adhesion between fillers (e.g., silica, clay) and polymer matrices in high-performance composites.
• Sealants and Adhesives: A key intermediate in formulating high-strength, weather-resistant sealants and adhesives, particularly in construction and automotive applications.
• Hydrophobic Coatings: Imparts water-repellent characteristics to surfaces in protective coating formulations.
• Chemical Synthesis Intermediate: Serves as a versatile building block for the synthesis of more complex organosilicon molecules and functional materials.

Quality Control

Our production of Isopropyltrimethoxysilane adheres to stringent quality management protocols. Each batch undergoes rigorous analytical testing, including Gas Chromatography (GC) for purity and identity confirmation, to ensure consistency and compliance with agreed specifications. Certificates of Analysis (COA) detailing all test results are provided with every shipment to guarantee supply reliability and product integrity for your critical processes.

Storage

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