Description

Allyldimethoxymethylsilane is a versatile organosilicon compound characterized by its reactive allyl and methoxy functional groups. This dual functionality makes it a valuable intermediate for introducing silicon-containing moieties into polymer backbones and organic molecules. It is primarily utilized in the synthesis of silicone polymers, coupling agents, and as a key building block in advanced material science. Industries such as specialty chemicals, adhesives & sealants, and coatings rely on this compound for developing products with enhanced properties.

Application

• Silicone Polymer Synthesis: A key monomer or cross-linking agent in the production of modified silicone resins and elastomers.
• Surface Modification & Coupling Agent: Used to functionalize inorganic surfaces like glass, silica, or metals to improve adhesion with organic polymers.
• Organic Synthesis Intermediate: Serves as a precursor in hydrosilylation and other reactions to create novel organosilicon compounds for research and development.
• Adhesive and Sealant Formulations: Imparts improved flexibility, weather resistance, and adhesion properties in high-performance formulations.
• Release Coatings and Liners: Employed in the manufacture of silicone-based release papers and films.
• Water Repellents: Used in treatments for textiles, construction materials, and stone to confer hydrophobic characteristics.

Quality Control

Our Allyldimethoxymethylsilane is manufactured under stringent process controls to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including Gas Chromatography (GC) and NMR spectroscopy, to verify identity, assay, and impurity profiles. Certificates of Analysis (COA) detailing all test results are provided with every shipment to support your quality assurance protocols.

Storage

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