Product Overview
n-Octyltriethoxysilane is a premium organosilicon compound engineered for advanced surface modification and hydrophobic protection. As a leading global manufacturer, we supply this high-performance silane coupling agent with strict quality control to ensure consistent batch-to-batch reliability. The molecule features a reactive triethoxy silyl group capable of bonding with inorganic substrates, paired with a long-chain octyl group that provides exceptional water repellency and compatibility with organic polymers.
This specialty chemical is widely recognized as a drop-in replacement for major industry standards, offering equivalent performance in demanding applications ranging from construction waterproofing to polymer composite reinforcement. Our production facilities adhere to international safety and quality management systems, guaranteeing a product purity of 98% or higher.
Key Industrial Applications
The versatility of n-Octyltriethoxysilane makes it indispensable across multiple sectors. In the construction industry, it serves as a highly effective waterproofing agent for masonry and concrete. Upon application, it penetrates the substrate and forms a durable hydrophobic layer that prevents water seepage while allowing vapor transmission. This protective barrier significantly mitigates damage from sunlight, acid rain, and alkali erosion, thereby extending the service life of architectural structures.
In the plastics and rubber industries, this silane functions as a critical surface treatment agent for inorganic fillers such as calcium carbonate, silica, and glass fibers. By modifying the filler surface energy, it improves dispersion within the polymer matrix and enhances interfacial adhesion. This results in improved mechanical properties, including tensile strength and impact resistance, while reducing viscosity during processing. Additionally, it acts as a superior dispersant for pigments, ensuring uniform color distribution and stability in coatings and masterbatches.

Quality Assurance and Handling
We understand that consistency is vital for industrial manufacturing processes. Every shipment of n-Octyltriethoxysilane is accompanied by a comprehensive Certificate of Analysis (COA) verifying all physical and chemical parameters. Our logistics network ensures safe and timely delivery globally, with packaging options tailored to your volume requirements, including 180kg iron drums and 880kg IBC containers.
For optimal stability, store the product in its original unopened container at temperatures below 25°C. Under these conditions, the shelf life is guaranteed for one year from the production date. While expired products may still be usable, we strongly recommend conducting quality testing before incorporation into critical formulations. As a non-dangerous good, transportation is streamlined, though standard chemical handling precautions should always be observed to ensure workplace safety.
