3,3-Bis(trimethoxysilyl)dipropylamine: A Versatile Silane Coupling Agent

Silane coupling agents are widely used in various industries as they enhance the compatibility between dissimilar materials, improve adhesion, and provide resistance against moisture, chemicals, and temperature fluctuations. Among the many silane coupling agents available in the market, 3,3-Bis(trimethoxysilyl)dipropylamine (CAS No. 82985-35-1) stands out for its versatility and effectiveness in diverse applications.

Also known as Evonik Degussa Dynasylan 1122, Bis(trimethoxysilylpropyl)amine, or 3-(Trimethoxysilyl)-N-[3-(trimethoxysilyl)propyl]-1-propylamine, this silane coupling agent is manufactured and supplied by INNO Specialty Chemicals, a leading chemical company based in China.

The chemical formula of 3,3-Bis(trimethoxysilyl)dipropylamine is C14H33NO6Si2, and its molecular weight is 383.58 g/mol. It has a clear and colorless liquid appearance with a boiling point of 320°C and a flashpoint of 154°C. The product is highly soluble in organic solvents such as ethanol, acetone, and chloroform and is stable under normal conditions.

The primary function of 3,3-Bis(trimethoxysilyl)dipropylamine is to act as a silane coupling agent between organic and inorganic materials. It contains two reactive trimethoxysilyl groups and one amine group that can react with various substrates such as glass, metals, ceramics, plastics, and composites. The silane groups can bond with the surface of the substrate, while the amine group can react with other functional groups such as carboxylic acids, epoxides, and isocyanates. This dual functionality makes 3,3-Bis(trimethoxysilyl)dipropylamine an ideal choice for many applications.

One of the main applications of 3,3-Bis(trimethoxysilyl)dipropylamine is in the production of adhesives and sealants. It can improve the adhesion strength of the adhesive to the substrate by forming a strong bond between the two materials. This coupling agent can also increase the water resistance and durability of the adhesive, making it suitable for outdoor applications.

In the construction industry, 3,3-Bis(trimethoxysilyl)dipropylamine is used as a surface modifier for cement and concrete. It can react with the hydroxyl groups of the cement to form a chemical bond, which enhances the mechanical strength and durability of the concrete. This silane coupling agent can also reduce the water absorption and increase the frost resistance of the concrete, making it more suitable for harsh weather conditions.

In the automotive industry, 3,3-Bis(trimethoxysilyl)dipropylamine is used as a coating agent for metals and alloys. It can improve the corrosion resistance and adhesion of the coating to the metal substrate, making it more durable and long-lasting. This silane coupling agent can also provide a barrier against moisture and chemicals, which is essential for the protection of the metal surface.

Apart from these applications, 3,3-Bis(trimethoxysilyl)dipropylamine is also used in the production of fiberglass, plastics, and rubber. It can improve the adhesion between the fibers and the matrix, increase the mechanical strength and flexibility of the materials, and reduce the water absorption and degradation of the materials.

In conclusion, 3,3-Bis(trimethoxysilyl)dipropylamine is a versatile and effective silane coupling agent that can enhance the performance of various materials in different applications. Its dual functionality, reactive silane groups, and amine group make it an ideal choice for many industries such as adhesives, construction, automotive, fiberglass, plastics, and rubber. INNO Specialty Chemicals is a reliable supplier of high-quality 3,3-Bis(trimethoxysilyl)dipropylamine, and their products are widely used in many countries around the world.
