n-Octyltrimethoxysilane

Product Overview

n-Octyltrimethoxysilane is a premium organosilicon compound designed for advanced surface modification and hydrophobic protection. As a key member of the alkylalkoxysilane family, this chemical exhibits exceptional reactivity with inorganic substrates, forming durable water-repellent layers that enhance material longevity. Our manufacturing process ensures high purity levels, making it an ideal choice for demanding industrial applications where performance consistency is critical.

This silane coupling agent functions by chemically bonding to surfaces such as concrete, minerals, and fillers. Upon hydrolysis, it creates a robust hydrophobic barrier that protects against moisture ingress, UV radiation, and chemical erosion. The result is significantly improved durability for construction materials and enhanced compatibility for composite polymers.

Key Specifications

Industrial Applications

The versatility of n-Octyltrimethoxysilane allows it to serve multiple roles across various sectors. Its primary function revolves around surface treatment and modification, providing tangible benefits in performance and lifespan.

• Construction Waterproofing: Acts as a penetrating sealer for masonry and concrete, forming an invisible hydrophobic layer that prevents water seepage while allowing vapor transmission.
• Filler Surface Treatment: Modifies inorganic fillers used in plastics, rubbers, and resins to improve dispersibility and interfacial compatibility.
• Pigment Dispersion: Enhances the distribution of pigments in coatings and inks, resulting in better color strength and stability.
• Protective Coatings: Provides resistance against acid, alkali, and sunlight erosion, extending the service life of protected substrates.

Storage and Handling

To maintain optimal quality, this product should be stored in its original unopened container at temperatures below 25℃. The shelf life is one year from the production date when stored under recommended conditions. Expired products may still be usable but must pass quality testing before application. As this substance falls under Dangerous Goods Classification 6.1, all handling procedures must adhere to relevant safety regulations and local transportation laws. Proper personal protective equipment is required during handling to ensure workplace safety.
