Efficient Silicon-Based Coupling Agents: Evonik's Dynasylan MTMO and VPSi163

Silicon-based coupling agents are essential components in many industrial processes, where they help to improve the adhesion and compatibility of different materials. These coupling agents are used in a wide range of applications, from coatings and adhesives to textile and paper production. Among the most effective silicon-based coupling agents available on the market are DOWSIL Z-6062, Shin-Etsu KBM-803, WACKER GENIOSIL GF 70, Momentive Silquest A-189, and Evonik Degussa Dynasylan MTMO and VPSi163.

Evonik Degussa, a global leader in specialty chemicals, has been producing high-quality silicon-based coupling agents for over 50 years. These products are designed to improve the adhesion, wetting, and dispersibility of different substrates, such as metals, glass, ceramics, and polymers. In particular, Evonik's Dynasylan MTMO and VPSi163 are highly efficient coupling agents that offer numerous benefits to manufacturers, suppliers, and factories in various industries.

Dynasylan MTMO (3-(trimethoxysilyl)propanethiol) and VPSi163 ((γ-Mercaptopropyl)trimethoxysilane) are sulfur-functionalized silanes that have a thiol group (-SH) in their molecular structure. This thiol group can react with metal oxides, such as aluminum, iron, and zinc, as well as with organic compounds, such as epoxy, polyester, and polyurethane resins. This reaction leads to the formation of strong covalent bonds that enhance the adhesion and mechanical properties of the materials.

One of the main advantages of Dynasylan MTMO and VPSi163 is their ability to improve the corrosion resistance of metal surfaces. When applied to metal substrates, these coupling agents can form a protective layer that prevents the penetration of moisture and chemicals, thus reducing the risk of rust and oxidation. This is particularly important in automotive and aerospace applications, where metal parts are exposed to harsh environmental conditions.

Another benefit of Dynasylan MTMO and VPSi163 is their compatibility with different solvents and formulations. These coupling agents can be easily dissolved in polar and non-polar solvents, such as water, ethanol, and toluene, and can be incorporated into various formulations, such as coatings, adhesives, and sealants. This versatility allows manufacturers to tailor the properties of their products to specific requirements, such as viscosity, curing time, and adhesion strength.

Moreover, Dynasylan MTMO and VPSi163 are highly stable and resistant to hydrolysis. This means that they can maintain their effectiveness even in humid and acidic environments, where other coupling agents may degrade and lose their properties. This stability also ensures a longer shelf life and easier handling and storage of the products.

In terms of performance, Dynasylan MTMO and VPSi163 have been shown to outperform other sulfur-functionalized silanes, such as Shin-Etsu KBM-803 and WACKER GENIOSIL GF 70, in several aspects. For instance, Dynasylan MTMO has a higher reactivity and can form stronger bonds with metal surfaces than KBM-803. VPSi163, on the other hand, has a lower viscosity and can penetrate deeper into porous substrates than GF 70, thus improving the adhesion and corrosion resistance of these substrates.

Finally, Evonik Degussa offers a reliable and efficient supply chain for Dynasylan MTMO and VPSi163. The products are produced in a state-of-the-art facility in China by Ningbo Inno Pharmchem Co., Ltd, a subsidiary of Evonik Degussa. This factory has a production capacity of 3000 tons per year and is certified according to ISO 9001 and ISO 14001 standards. Moreover, Evonik Degussa provides technical support and expertise to help customers optimize their formulations and processes.

In conclusion, Dynasylan MTMO and VPSi163 are efficient and versatile silicon-based coupling agents that offer numerous benefits to manufacturers, suppliers, and factories in different industries. These products can improve the adhesion, wetting, and dispersibility of different substrates, enhance the corrosion resistance of metal surfaces, and offer compatibility with various solvents and formulations. Moreover, Dynasylan MTMO and VPSi163 are stable, resistant to hydrolysis, and produced by a reliable and efficient supply chain. Therefore, if you are looking for high-quality coupling agents for your industrial processes, consider Evonik Degussa's Dynasylan MTMO and VPSi163.
