N-(2-Aminoethyl)-3-aminopropyltrimethoxysilane, commonly known as Silane KH-792 or GX-792, with CAS No. 1760-24-3, stands as a highly effective and versatile amino-functional silane coupling agent. This chemical compound plays a crucial role in a wide array of industrial applications by significantly improving the bond between organic polymers and inorganic substrates. Its unique molecular structure, featuring both polyamino functionality and a trifunctional silane group, allows it to act as a bridge, enhancing the overall performance and durability of composite materials, adhesives, and sealants.

The polyamino functionality of Silane KH-792 provides reactive sites for various amino-reactive resins, facilitating excellent wetting of diverse substrates. Simultaneously, its trifunctional silane group ensures superior adhesion to inorganic surfaces such as metal, glass, and a variety of mineral fillers. This dual functionality is particularly beneficial in complex formulations where robust adhesion across dissimilar materials is critical. A key advantage of incorporating Silane KH-792 is its ability to often eliminate the need for separate primers, streamlining manufacturing processes and reducing overall costs while maintaining or even improving bond strength.

In the realm of sealants, Silane KH-792 proves invaluable. Its addition to one- and two-part RTV silicones and hybrid silane-crosslinked sealants dramatically improves adhesion to common construction materials like glass, steel, aluminum, and concrete. Furthermore, when used in conjunction with silylating urethane polymers (such as in SPUR Technology-based systems), it can enhance adhesion to a broad spectrum of plastics. Similarly, in polysulfide sealants, Silane KH-792 at typical loadings of 0.5 to 1.0 percent by weight ensures better adhesion to various substrates, often leading to cohesive failure within the sealant rather than adhesive failure at the interface. For plastisol sealants, replacing polyaminoamide adhesion promoters with 0.5 to 1.5 weight percent of Silane KH-792 not only improves bonding to metal substrates but also results in a lighter color and a bubble-free cured compound, enhancing aesthetic appeal and performance.

Beyond sealants, Silane KH-792 is a powerful additive in phenolic and epoxy molding compounds. Its inclusion helps to significantly reduce the water absorption of molded composites, which in turn leads to improved wet electrical properties, particularly at low frequencies. High-temperature strength properties of these compounds are also considerably enhanced, making them suitable for demanding environments. This silane's capacity to form a durable bond between organic and inorganic materials is central to its wide adoption, enabling the creation of high-performance heterogeneous environments and composite structures.

The typical physical properties of Silane KH-792 include its appearance as a clear, colorless transparent liquid. It boasts a minimum purity of 97.0%, a specific gravity at 20°C ranging from 1.010 to 1.030, and a refractive index at 20°C between 1.439 and 1.447. The color, Pt-Co, is typically max 25, with a flash point of 150 °C and a viscosity at 25 °C of approximately 6.5 cSt. These consistent specifications ensure reliable performance across various applications.
