    Description

    3-Aminopropyltriethoxysilane, also known as γ-aminopropyltriethoxysilane (KH-550), is a bifunctional organosilane with active amino groups and hydrolyzable ethoxysilyl groups. It is a colorless liquid with characteristic ammonia odor, miscible with alcohols, aliphatic hydrocarbons and aromatic hydrocarbons.

    Applications

    It is a widely used silane coupling agent. It can be applied in mineral-filled thermoplastic and thermosetting resins such as phenolic resin, polyester, epoxy resin, PBT, polyamide and polycarbonate. It improves the mechanical strength and electrical properties of composite materials, and enhances the wettability and dispersion of fillers in polymers.

    It acts as an excellent adhesion promoter for polyurethane, epoxy, nitrile, phenolic adhesives and sealants. It improves pigment dispersion and adhesion to glass, aluminum and iron metals. It is also suitable for polyurethane, epoxy and acrylic latex coatings.

    Other applications include resin sand casting, glass fiber and mineral wool production, and abrasive wheel manufacturing to improve bonding strength and moisture resistance. Applicable polymer systems include epoxy, phenolic, melamine, nylon, PVC, polyacrylate, polyurethane, polysulfide rubber, nitrile rubber and more.

    Safety & Storage

    Store in sealed container at room temperature, away from moisture, acids and strong oxidants. Suitable protective equipment should be worn during handling. Occupational operation needs good ventilation.

    ECHEMI Editorial Reference
    (3-Aminopropyl)triethoxysilane, this unique organosilicon compound, identified by its formula C11H27NO3Si, has taken its place in the chemical world. Its molecular structure is exquisite, ingenious fusion of amino (-NH2) this active group and three ethoxy (-OEt) elegant posture, giving it extraordinary reactivity and multi-functional characteristics. This compound, often colorless to pale yellow liquid form in front of the world, like a gentle beauty, quietly exuding a unique charm. When it comes to the physical properties of (3-Aminopropyl)triethoxysilane, it is necessary to mention its excellent water dispersion and adhesion. These two features are like its inner soul, which makes it easy to use in many application scenarios. When it is gently sprinkled on the surface of the material, it seems to be a skillful craftsman who closely connects the water with the material with superb skills, and at the same time lays a solid protective layer on the surface, so that the performance of the material can be further improved. In the industrial sector, the (3-Aminopropyl)triethoxysilane has shown exceptional value. As a leader in adhesives and crosslinkers, it can not only significantly improve the adhesion of materials, make the combination between various materials more closely, but also effectively extend the service life of materials, bringing great convenience and economic benefits to industrial production. In addition, the presence of its amino functional group makes it a tiger, becoming a leader in the field of coupling agents. In the coatings, rubber and plastics industries, it seems to be a messenger of wisdom, cleverly promoting the harmonious coexistence between inorganic materials and organic polymers, so that these materials with different properties can work together to create more excellent performance. In order to better understand the important role of (3-Aminopropyl)triethoxysilane in industrial applications, let's take a look at a few concrete examples. In the coating industry, the compound is often used as a coating additive to improve the adhesion and weather resistance of the coating, making the protective effect of the coating more significant. At the same time, it can also form good compatibility with pigments and fillers in the paint, so that the overall performance of the paint is further improved. In the rubber and plastics industry, (3-Aminopropyl)triethoxysilane is often used as a crosslinking agent or viscosifier to improve the mechanical properties, heat resistance and aging resistance of rubber and plastics by increasing the cross-linking density and the intermolecular interaction force. It is worth mentioning that the wide application of (3-Aminopropyl)triethoxysilane is also supported by numerous empirical studies and statistical data. According to relevant studies, after adding an appropriate amount of this compound to the coating, the adhesion of the coating can be increased by more than 30%, and the weather resistance is also significantly improved. In the rubber and plastics industry, when it is used as a crosslinking agent or tackifier, the key performance indicators such as tensile strength, tear strength and wear resistance of the material are significantly improved. These empirical studies and statistical data not only fully prove the excellent performance and application value of (3-Aminopropyl)triethoxysilane, but also provide strong support for its application in more fields.
