Description

Silane, Trimethyl[3-(1-Methylethyl)Oxiranyl]- (9Ci) is a specialized organosilicon compound featuring both an epoxide (oxirane) ring and a reactive silane group. This unique bifunctional structure makes it a valuable coupling agent and precursor in advanced material synthesis, enabling strong interfacial adhesion between organic polymers and inorganic substrates. It is primarily utilized by manufacturers in the coatings, adhesives, and composites industries seeking to enhance material performance, durability, and chemical resistance.

Application

• Surface Modification Agent: Used to functionalize glass, silica, metals, and other inorganic surfaces to improve compatibility with organic resins.
• Adhesive & Sealant Formulations: Acts as an adhesion promoter in epoxy, polyurethane, and silicone-based systems, particularly for demanding environments.
• Composite Materials: Enhances the interfacial bonding between reinforcing fibers (e.g., glass, carbon) and polymer matrices in high-performance composites.
• Protective & Functional Coatings: Incorporated into coatings to improve corrosion resistance, scratch resistance, and adhesion to difficult substrates.
• Crosslinking Agent: Serves as a reactive intermediate in the synthesis of silicone-epoxy hybrid polymers and networks.
• Electronic Encapsulants: Used in formulations for potting and encapsulating electronic components to provide moisture resistance and mechanical stability.

Quality Control

Our production of Silane, Trimethyl[3-(1-Methylethyl)Oxiranyl]- (9Ci) adheres to stringent quality management protocols. Each batch undergoes rigorous analytical testing, including GC, HPLC, and NMR, to ensure high purity and consistent performance. A comprehensive Certificate of Analysis (COA) detailing identity, assay, and impurity profiles is provided with every shipment to support your quality assurance and regulatory needs.

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 (moisture-sensitive) nature, containers must be kept tightly sealed under a dry inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation.
