Degussa Dynasylan 1122: A Reliable Solution for Surface Modification

In the world of chemical manufacturing, surface modification agents play a crucial role in enhancing the properties of various materials. The use of such agents has become increasingly common in industries such as construction, automotive, and electronics, to name a few. One such versatile surface modification agent is Degussa Dynasylan 1122, manufactured and supplied by INNO Specialty Chemicals from China.

Degussa Dynasylan 1122, also known as Bis[3-(triethoxysilyl)propyl]amine, is a clear, colorless liquid with a molecular weight of 385.6 g/mol. It is a bifunctional silane coupling agent that contains both amino and triethoxysilyl groups. The amino group enables it to react with various organic and inorganic substrates, while the triethoxysilyl group allows for easy bonding with a variety of surfaces, including glass, metal, and minerals.

The primary application of Degussa Dynasylan 1122 is as a surface modifier for mineral-filled polymer composites. When added to the composite matrix, it enhances the adhesion between the mineral filler and the polymer matrix. This results in improved mechanical properties, including tensile strength, flexural strength, and impact resistance. In addition, it improves the thermal and electrical properties of the composite, making it suitable for use in high-temperature and electrical applications.

Another significant application of Degussa Dynasylan 1122 is as a coupling agent for glass fibers. The silane coupling agent forms a strong chemical bond between the glass fibers and the polymer matrix, resulting in improved mechanical properties, such as higher tensile and flexural strength, and better impact resistance. Moreover, it reduces water absorption, which can lead to improved dimensional stability and durability of the composite.

In the construction industry, Degussa Dynasylan 1122 is used as a surface modifier for concrete and cementitious materials. It improves the adhesion between the cement matrix and the reinforcement material, such as steel or glass fibers, resulting in higher strength and durability of the composite. Additionally, it enhances the water repellency of the concrete, reducing the risk of water damage and improving the longevity of the structure.

Apart from these applications, Degussa Dynasylan 1122 is also used as a surface modifier for various materials, including textiles, coatings, and adhesives. It improves the wetting and dispersing properties of the material, resulting in better adhesion, improved durability, and resistance to environmental factors such as UV radiation and moisture.

In conclusion, Degussa Dynasylan 1122 is a versatile and reliable surface modification agent that offers numerous benefits to various industries. Its ability to enhance the mechanical, thermal, and electrical properties of materials makes it an essential component in the manufacture of high-performance composites. As the demand for high-performance materials continues to grow, the use of surface modification agents such as Degussa Dynasylan 1122 is expected to increase significantly in the coming years.
