Description

10-Oxiran-2-Yldecyltrimethoxysilane is a specialized organosilane coupling agent featuring both an epoxy (oxirane) ring and a long alkyl chain terminated with trimethoxysilane groups. This unique bifunctional structure enables it to act as a powerful molecular bridge, creating strong covalent bonds between inorganic substrates and organic polymer matrices. It is essential for formulators and material scientists seeking to enhance the mechanical properties, durability, and adhesion of composite materials. Key industries that rely on this advanced silane include advanced composites, coatings, adhesives, and sealants.

Application

• As a coupling agent in glass or mineral fiber-reinforced polymer composites (e.g., epoxy, polyester, polyamide) to improve interfacial adhesion and mechanical strength.
• Surface pretreatment for glass, metals, and minerals to promote adhesion of paints, coatings, and adhesives.
• Modification of fillers (e.g., silica, clay) to improve their dispersion and compatibility within plastic and rubber compounds.
• Crosslinking agent or reactive intermediate in the synthesis of specialty silicone polymers and hybrid organic-inorganic materials.
• Enhancing the water resistance and weatherability of mineral-filled sealants and construction materials.
• Improving the bond strength and durability of dental composites and other biomedical materials.

Quality Control

Our production of 10-Oxiran-2-Yldecyltrimethoxysilane adheres to stringent quality management protocols. Every batch undergoes comprehensive analytical testing, including assay (GC/HPLC), epoxy value determination, and purity verification, to ensure consistency and performance. Certificates of Analysis (COA) documenting all critical parameters are provided with each shipment. We support our global clients with compliance documentation relevant to their regional regulatory requirements.

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. Keep away from heat and incompatible materials such as strong acids, bases, and oxidizing agents.
