Description

Acetoxyethyltris(Dimethylamino)Silane is a highly reactive organosilicon compound, specifically a functionalized aminosilane, designed for advanced material synthesis. Its core value lies in its dual functionality, where the acetoxyethyl group offers hydrolytic stability and the tris(dimethylamino) groups provide potent reactivity as a coupling agent and surface modifier. This makes it an essential precursor for manufacturers in the silicone polymers, advanced coatings, and electronics industries seeking to enhance material adhesion, cross-linking density, and surface properties.

Application

• As a key coupling agent and adhesion promoter in silicone sealants, RTV (Room Temperature Vulcanizing) rubbers, and high-performance elastomers.
• Surface modification and priming agent for inorganic fillers (e.g., silica, glass fibers) to improve dispersion and interfacial bonding in composite materials.
• Precursor for the synthesis of specialty silicon-based polymers and resins with tailored properties for coatings and release layers.
• Intermediate in the production of advanced materials for the semiconductor and microelectronics industries, including low-k dielectrics and passivation layers.
• Used in the formulation of water repellents and protective coatings for construction and automotive applications.
• Catalyst or co-catalyst component in organic synthesis and polymerization reactions.

Quality Control

Our Acetoxyethyltris(Dimethylamino)Silane is manufactured under stringent quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including assay and impurity profiling, to meet exacting customer specifications. A detailed Certificate of Analysis (COA) is provided with every shipment, confirming compliance with agreed parameters.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under a dry inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation.
