Product Technical Details

Product Overview

(N-Anilino)methyltriethoxysilane represents a high-performance class of organosilane coupling agents designed for demanding industrial applications. Featuring a unique anilino functional group attached to a methyltriethoxysilane backbone, this compound offers distinct chemical reactivity that surpasses conventional silanes. The integration of the nitrogen-containing aromatic group enhances compatibility with specific polymer matrices, facilitating robust interfacial bonding between inorganic substrates and organic resins. This molecular design is engineered to optimize surface modification processes, ensuring reliable performance in critical manufacturing environments.

Key Performance Characteristics

The chemical stability of this silane is a defining feature, particularly regarding thermal resistance. The silicon-carbon bond within the structure exhibits remarkable resilience against thermal degradation, maintaining integrity at elevated temperatures where other coupling agents might fail. This property ensures that composite materials retain their mechanical strength and structural cohesion over extended service lives. Furthermore, the hydrolytic stability provided by the ethoxy groups allows for controlled cross-linking reactions, balancing processing speed with final product durability.

  • Delivers exceptional adhesion promotion on metals, glass, ceramics, and cement surfaces
  • Accelerates cross-linking kinetics in room temperature vulcanizing (RTV) silicone rubber
  • Provides superior heat resistance compared to standard gamma-functional coupling agents
  • Enhances tensile strength and impact resistance in mineral-filled plastic compounds
  • Ensures long-term water resistance and environmental stability for outdoor applications

Industrial Applications

This versatile coupling agent is primarily employed as a cross-linking agent in the production of RTV silicone rubber, where it significantly improves cure rates and final physical properties. Beyond silicone systems, it is widely adopted in the manufacturing of glass fiber reinforced plastics (GFRP) and mineral-filled thermoplastics. The ability to prevent bond breakage under thermal stress makes it ideal for automotive components, electronic encapsulation, and construction sealants. Manufacturers utilize this chemical to achieve drop-in performance improvements in formulations requiring high adhesion and thermal stability.

Packaging Storage and Handling

Quality preservation is paramount for organosilane products. This material is packaged in 20Kg plastic drums, 200Kg steel drums, or 1000Kg intermediate bulk containers (IBC) to ensure safety during transit. Storage protocols require keeping the product in its original unopened container at temperatures not exceeding 25℃. Exposure to moisture should be minimized to prevent premature hydrolysis. The established shelf life is one year from the date of production. While classified as non-dangerous goods, standard chemical handling procedures should be followed. Expired product must undergo quality testing before reintroduction into production lines to guarantee specification compliance.
