Properties

N-Aminoethyl-3-Aminopropylmethyldimethoxysilane is a colorless to yellowish liquid with a molecular weight of 222.37 g/mol. Its chemical formula is C8H22N2O2Si, and its CAS number is 3069-29-2. This silane coupling agent has a boiling point of 173-175 °C, a flashpoint of 61 °C, and a density of 0.96 g/cm3. It has a refractive index of 1.442 at 20 °C and a viscosity of 2.2 cSt at 25 °C.

The product is soluble in water, ethanol, and other polar solvents. It is stable under normal conditions but can hydrolyze in the presence of water or moisture to form silanol groups. Therefore, it should be stored in a dry and cool place to avoid contact with water or moisture.

Applications

N-Aminoethyl-3-Aminopropylmethyldimethoxysilane is a versatile silane coupling agent that has a wide range of applications in various industries. It is primarily used as a surface modifier to enhance the adhesion, dispersion, and compatibility of inorganic fillers, pigments, and polymers. It can also act as a crosslinking agent, a curing agent, or a functionalizing agent in many applications.

In the rubber industry, this product is used as a coupling agent for silica-filled rubber compounds. It can improve the mechanical properties, such as tensile strength, tear resistance, and abrasion resistance, of the rubber products. It can also reduce the rolling resistance and improve the fuel efficiency of tires.

In the coatings industry, N-Aminoethyl-3-Aminopropylmethyldimethoxysilane can be used as a primer or an adhesion promoter for metal, glass, and other substrates. It can enhance the wetting and spreading of the coating materials, leading to a smoother and more durable surface. It can also improve the scratch resistance and the chemical resistance of the coatings.

In the adhesives and sealants industry, this product can be used as a coupling agent or a crosslinking agent for epoxy, polyurethane, and other reactive systems. It can improve the bonding strength and the durability of the adhesives and sealants. It can also reduce the shrinkage and the brittleness of the cured products.

In the composites industry, N-Aminoethyl-3-Aminopropylmethyldimethoxysilane can be used as a sizing agent or a coupling agent for glass fibers, carbon fibers, and other reinforcing materials. It can improve the interfacial bonding between the fibers and the matrix, leading to a higher strength and stiffness of the composites. It can also reduce the moisture absorption and the delamination of the composites.

Safety

N-Aminoethyl-3-Aminopropylmethyldimethoxysilane is a hazardous substance that should be handled with care. It can cause skin and eye irritation, respiratory sensitization, and allergic reactions. Therefore, protective equipment, such as gloves, goggles, and masks, should be worn when handling this product. It should also be stored and transported in accordance with the safety regulations and guidelines.

Conclusion

N-Aminoethyl-3-Aminopropylmethyldimethoxysilane is a versatile silane coupling agent that has a wide range of applications in various industries.
