Diethylaminomethyltriethoxysilane

Product Overview

Diethylaminomethyltriethoxysilane is a highly reactive organosilicon compound designed for advanced industrial applications. As an alpha-functional silane coupling agent, it possesses unique chemical properties that facilitate superior bonding between organic polymers and inorganic substrates. This product is characterized by its clear liquid appearance, typically ranging from colorless to pale yellow, indicating high purity levels suitable for demanding manufacturing processes.

The molecular structure features ethoxy groups that readily hydrolyze to form silanols, which then condense with hydroxyl groups on surfaces such as glass, metals, and minerals. Simultaneously, the diethylaminomethyl functionality provides reactivity with organic matrices, creating a robust chemical bridge that enhances material performance significantly.

Key Performance Features

• Rapid cross-linking speed for efficient production cycles in silicone rubber manufacturing.
• Exceptional adhesion promotion between silicone rubber and various metal substrates.
• Improved mechanical strength and toughness in reinforced composite materials.
• Enhanced water resistance and weatherability for outdoor applications.
• Versatile functionality as both a curing agent and a surface treatment modifier.

Technical Specifications

Industrial Applications

This silane coupling agent is extensively utilized as a cross-linking agent for room temperature vulcanized (RTV) silicone rubber. Its fast curing characteristics make it ideal for high-throughput manufacturing environments where cycle time is critical. Beyond rubber applications, it serves as a reinforcing agent for synthetic resins, significantly improving the interfacial bonding between resin matrices and fillers like glass fiber.

In the textile industry, this product functions as a raw material for fabric finishing agents, imparting durability and specific surface properties to fibers. It is also employed as a surface treatment agent when bonding silicone rubber to metal components, ensuring long-term structural integrity in automotive and aerospace assemblies. Additionally, it acts as a curing agent and tackifier for epoxy resin systems, enhancing overall composite performance.

Packaging and Storage

To maintain product stability and safety, Diethylaminomethyltriethoxysilane is packaged in 20kg plastic drums, 180kg drums, or 900kg IBC containers depending on customer volume requirements. Storage should be maintained in the original unopened container at temperatures of 25℃ or below. The recommended shelf life is one year from the production date. Expired products may still be usable subject to passing quality control tests. Handlers must observe appropriate safety protocols given its classification as a Class 8 dangerous good.
