Description

Dimethylbis(S-Butylamino)Silane is a specialized organosilicon compound featuring two sec-butylamino groups bonded to a silicon center. This chemical matters as a versatile intermediate and coupling agent, enabling the synthesis of advanced silicone polymers and surface-modified materials. Industries requiring high-performance silane coupling agents, such as advanced composites, adhesives, and specialty coatings, will find this product essential for enhancing material properties and interfacial adhesion.

Application

• As a key silane coupling agent in fiberglass-reinforced composites and mineral-filled plastics.
• An intermediate for the synthesis of specialty silicone polymers and resins with tailored properties.
• Surface modification agent for inorganic fillers (e.g., silica, clay) to improve dispersion and compatibility in polymer matrices.
• Adhesion promoter in sealant, adhesive, and coating formulations for demanding substrates.
• Precursor for chemical vapor deposition (CVD) processes to deposit silicon-containing thin films.
• Used in research and development of novel organosilicon chemistry and catalytic systems.

Quality Control

Our Dimethylbis(S-Butylamino)Silane is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including GC, NMR, and Karl Fischer titration, to ensure high purity and consistent performance. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is 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). This product is hygroscopic (moisture-sensitive). Keep the container tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent degradation from atmospheric moisture and oxygen.
