In the diverse landscape of chemical raw materials, coupling agents play a critical role in enhancing the performance and durability of finished products across numerous industries. Among these, silane coupling agents stand out for their unique ability to bridge the gap between organic polymers and inorganic substrates, creating strong, stable chemical bonds. One particularly valuable compound in this category is N-(2-aminoethyl)-3-aminopropylmethyl-dimethoxysilane, identified by its CAS number 3069-29-2.

Silane CAS 3069-29-2 is a highly effective amino-functional silane coupling agent. Its molecular structure features reactive amino groups that can interact with organic matrices and hydrolyzable alkoxy groups that can bond with inorganic surfaces like glass, metal, concrete, and mineral fillers. This bifunctional nature is the key to its versatility and performance as an adhesion promoter and material modifier.

Physically, this silane presents as a colorless, clear liquid, making it easy to handle and incorporate into various formulations without impacting the visual appearance of the final product, provided it is used within recommended concentrations. Its typical properties include a specific gravity in the range of 0.965-0.975 g/cm³ at 20°C and a purity of 98.0% minimum. The boiling point is listed around 265°C, indicating a relatively low volatility for a liquid chemical.

The benefits derived from incorporating Silane CAS 3069-29-2 into formulations are numerous and impactful. One of its primary advantages is its potent adhesion promoting capability. It significantly improves the bond strength between disparate materials, which is crucial in applications ranging from sealants and adhesives to coatings and composites. Unlike some adhesion promoters, this silane can achieve strong bonds without requiring the use of special primers in many systems, simplifying manufacturing processes and reducing overall costs.

Furthermore, Silane CAS 3069-29-2 contributes to improved mechanical properties. In elastomeric systems, for example, it enhances adhesion while simultaneously maintaining or improving elongation, leading to more flexible and durable bonds. Its difunctional nature contributes to good stability, particularly in waterborne systems, which is increasingly important for developing environmentally friendly formulations. The use of this silane can also lead to improved shelf-life for formulated products, maintaining their performance characteristics over time.

The applications of Silane CAS 3069-29-2 are wide-ranging. It is widely used as a vital auxiliary agent in the textile industry, improving the performance of finishes and treatments on fabrics. In the production of sealants and adhesives, it is an indispensable additive. For RTV silicones and hybrid silane-crosslinked sealants, adding just 0.5 to 1.0 percent by weight of this silane dramatically improves adhesion to various substrates like glass, aluminum, and concrete, often resulting in cohesive failure within the sealant itself rather than adhesive failure at the interface.

Polysulfide sealants also benefit greatly from the inclusion of Silane CAS 3069-29-2, showing enhanced adhesion to glass, aluminum, and steel. Its ease of dispersion ensures homogeneous incorporation into the sealant matrix. Similarly, in plastisol sealants, replacing traditional polyaminoamide adhesion promoters with this silane leads to improved bonding to metal substrates. The resulting silane-modified plastisol sealants not only exhibit increased strength but also have a superior aesthetic, being very light in color and curing to a bubble-free compound.

Beyond sealants, Silane CAS 3069-29-2 is valuable as an additive in reinforced plastics and composites, specifically in phenolic and epoxy molding compounds. Its inclusion significantly reduces the water absorption of the molded materials. This reduction in moisture uptake is critical for maintaining performance in humid or wet environments, particularly for electrical applications where it leads to improved wet electrical properties, especially at lower frequencies. It helps preserve the dielectric strength and insulation resistance of composite parts.

Other documented uses include its function as an auxiliary agent in oil drilling, water treatment, rubber, leather, and as a component in surfactant formulations. In these diverse fields, its ability to modify surfaces, improve dispersion, or act as a coupling agent contributes to enhanced process efficiency and product quality.

As a raw material, Silane CAS 3069-29-2 is typically packaged in various sizes to meet industrial demands, including smaller drums and larger intermediate bulk containers (IBCs) of 950kg. This flexibility in packaging facilitates its transport and use in manufacturing facilities of different scales.

Understanding the properties and applications of a high-performance chemical like Silane CAS 3069-29-2 is essential for formulators seeking to optimize their products. Its role as a versatile amino silane coupling agent provides solutions for challenging adhesion problems and enables the development of materials with improved mechanical and environmental resistance.

For companies operating in the chemical industry, securing a reliable manufacturer and supplier of Silane CAS 3069-29-2 is a key business consideration. Evaluating the current market price and availability is crucial for production planning and cost control.
