n-Butyltriethoxysilane

Product Overview

n-Butyltriethoxysilane is a premium organosilicon compound widely recognized for its exceptional performance as a coupling agent and surface modifier. This colorless to straw-colored liquid serves as a critical component in enhancing the interface between organic polymers and inorganic substrates. Manufactured under strict quality control standards, our product ensures consistent molecular integrity and reactivity, making it an ideal choice for demanding industrial applications.

As a leading global manufacturer, we provide this silane with a purity level exceeding 97 percent, verified through rigorous gas chromatography analysis. The chemical structure features a butyl group attached to a silicon atom bonded with three ethoxy groups, facilitating effective hydrolysis and condensation reactions on various surfaces.

Key Chemical Properties

The efficacy of n-Butyltriethoxysilane lies in its unique physicochemical profile. Upon exposure to moisture, the ethoxy groups hydrolyze to form silanols, which subsequently condense to create stable siloxane bonds with hydroxyl groups on inorganic surfaces. This mechanism imparts lasting hydrophobicity and improves compatibility within composite matrices.

• High reactivity with glass, minerals, and metal oxides
• Excellent thermal stability up to specified boiling points
• Low viscosity for easy handling and dispersion
• Compatible with most organic resins and elastomers

Industrial Applications

This specialty chemical is extensively utilized across multiple sectors including rubber processing, plastics compounding, and coating formulations. Its primary function involves treating inorganic powders or filler materials to reduce water absorption and enhance mechanical strength. In the rubber industry, it improves the dispersion of silica fillers, leading to better wear resistance and lower rolling resistance in tires.

Furthermore, it acts as a water repellent in construction materials and adhesives. By modifying the surface energy of fillers, it ensures uniform distribution within the polymer matrix, thereby optimizing the final product's physical properties. Manufacturers seeking a drop-in replacement for existing surface treatments will find this product meets rigorous performance benchmarks.

Specifications And Packaging

Safety And Storage

Proper handling is essential to maintain product stability. n-Butyltriethoxysilane is flammable and moisture-sensitive. It should be stored in a cool, ventilated area away from direct sunlight and sources of ignition. Containers must remain tightly sealed to prevent premature hydrolysis. We recommend consulting the safety data sheet for comprehensive handling guidelines and emergency measures.

Our packaging options include 210-liter drums, with custom solutions available upon request to suit specific logistical requirements. As a trusted global manufacturer, we ensure timely delivery and provide complete documentation including certificates of analysis for every batch.
