Description

Acetoxymethyltriethoxysilane is a specialized organosilicon compound, also known as Acetoxymethyltriethoxysilane CAS NO 5630-83-1. It serves as a versatile coupling agent and reactive intermediate, valued for its ability to form stable bonds between organic polymers and inorganic materials. This silane is essential for manufacturers in the coatings, adhesives, and sealants industries seeking to enhance material compatibility, adhesion, and durability.

Application

• Crosslinking Agent in silicone-based sealants and adhesives to improve mechanical properties and thermal stability.
• Surface Modifier for inorganic fillers (e.g., silica, glass fibers) to improve dispersion and bonding within polymer matrices.
• Adhesion Promoter in primers and coatings for metals, glass, and plastics, particularly in demanding automotive and aerospace applications.
• Intermediate for the synthesis of more complex functional silanes and hybrid organic-inorganic materials.
• Moisture-Cure Component in room-temperature vulcanizing (RTV) silicone formulations.
• Filler Treatment in composite materials to reduce viscosity and enhance the interfacial strength between filler and resin.

Quality Control

Our Acetoxymethyltriethoxysilane is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including assay by GC or titration and impurity profiling, to ensure it meets precise specifications and consistent performance for industrial applications. A Certificate of Analysis (COA) documenting purity, identity, and key physical properties is provided with every shipment.

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/59-77°F). This product is hygroscopic (moisture-sensitive). Keep the container tightly sealed under a dry inert atmosphere (e.g., nitrogen) to prevent hydrolysis and maintain product integrity.
