Description

1,10-Bis-Trimethoxysilyldecane is a bifunctional organosilane coupling agent with a long, flexible alkylene bridge. This molecular structure is critical for its role in modifying interfaces between inorganic materials and organic polymers, enhancing adhesion and compatibility. It is essential for formulators and manufacturers in the advanced materials, coatings, and sealants industries seeking to improve the mechanical properties and durability of their composite products.

Application

• As a surface modifier and coupling agent for glass, silica, and metal oxides in composite materials.
• To improve the adhesion and water resistance of primers, paints, and coatings on metallic substrates.
• As a key cross-linking agent in the synthesis of silicone-modified polymers and hybrid organic-inorganic networks.
• For the hydrophobic treatment of mineral fillers and nanoparticles to enhance dispersion in plastic and rubber compounds.
• In the formulation of high-performance sealants and adhesives for construction and automotive applications.
• As a chemical anchor in dental and biomedical composite materials.

Quality Control

Our 1,10-Bis-Trimethoxysilyldecane is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including assay and impurity profiling, to ensure consistency and high purity suitable for industrial and R&D applications. A Certificate of Analysis (COA) detailing specific results 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). Due to its hygroscopic (moisture-sensitive) nature, containers must be kept tightly sealed after opening to prevent hydrolysis and degradation. Keep away from strong acids and bases.
