Description

10-Isocyanatodecyltrimethoxysilane, 95% CAS NO 1310372-82-7 is a high-purity organosilane coupling agent featuring a reactive isocyanate group and hydrolyzable methoxysilyl group on a long alkyl chain. This dual functionality is critical for creating strong, durable covalent bonds between inorganic substrates and organic polymers. It is an essential material for formulators and manufacturers seeking to enhance adhesion, mechanical properties, and long-term stability in composite systems. Key industries that rely on this specialty silane include advanced composites, coatings, adhesives, and sealants.

Application

• Surface Modification Agent: Priming glass, metal, or mineral surfaces to improve the adhesion of paints, coatings, and adhesives.
• Composite Reinforcement: Acting as a coupling agent in fiberglass, carbon fiber, or mineral-filled polymer composites (e.g., nylon, polypropylene) to enhance interfacial bonding and mechanical strength.
• Adhesive & Sealant Formulation: Improving the bond strength and moisture resistance of polyurethane (PU) and silicone-based adhesives and sealants.
• Rubber Compounding: Enhancing the filler-matrix interaction in silica-filled rubber compounds for tires and industrial rubber goods, leading to reduced rolling resistance and improved wear.
• Hybrid Material Synthesis: Serving as a key monomer or crosslinker in the synthesis of organic-inorganic hybrid (OIH) materials and sol-gel coatings.
• Waterproofing Treatments: Formulating durable water repellents (DWR) for textiles, leather, and construction materials.

Quality Control

Our 10-Isocyanatodecyltrimethoxysilane is manufactured under strict quality management protocols. Each batch undergoes rigorous analytical testing, including assay by titration or HPLC, to ensure the specified purity and functional group integrity. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing key parameters such as purity, isocyanate content, and moisture level. Our quality commitment ensures batch-to-batch consistency for your critical formulation and production processes.

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 a dry inert atmosphere (e.g., nitrogen or argon) to prevent hydrolysis and polymerization. Isocyanate-containing materials should be stored separately from moisture, alcohols, amines, and other reactive compounds.
