Description

1,2-Bis(Trimethoxysilyl)Decane is a specialized organosilicon compound, specifically a long-chain bis-silane coupling agent. This product is engineered to provide superior adhesion promotion and hydrophobic modification between organic polymers and inorganic substrates. It is essential for industries requiring durable, water-resistant composite materials and high-performance surface treatments. Key users include manufacturers in the advanced materials, coatings, and specialty chemical sectors.

Application

• Crosslinking Agent in silicone rubber and high-temperature resistant elastomers.
• Surface Modifier for fillers (e.g., silica, glass beads) to improve dispersion and compatibility in polymer matrices.
• Adhesion Promoter in sealants, adhesives, and coatings for metals, glass, and minerals.
• Hydrophobic Agent for creating water-repellent surfaces on construction materials and textiles.
• Precursor for Hybrid Materials in sol-gel processes for advanced ceramics and nanocomposites.
• Coupling Agent in fiber-reinforced plastics (FRP) to enhance the interfacial bond between resin and reinforcement.

Quality Control

Our production of 1,2-Bis(Trimethoxysilyl)Decane adheres to stringent quality management protocols. Each batch undergoes comprehensive analytical testing, including assay (GC/HPLC), identity confirmation (IR, NMR), and impurity profiling, to ensure consistency and high purity. Certificates of Analysis (COA) are provided with every shipment, documenting all critical quality attributes. We are committed to meeting the specific requirements of our global B2B partners.

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 material is hygroscopic (moisture-sensitive); containers must be kept tightly sealed and under a dry inert atmosphere (e.g., nitrogen) after opening to prevent hydrolysis and maintain product integrity. Keep away from heat and incompatible materials such as strong acids and bases.
