Degussa Dynasylan 3403: A Versatile Silane Coupling Agent for Enhanced Adhesion

If you are looking for a reliable and efficient silane coupling agent to improve the adhesion of your materials, then Degussa Dynasylan 3403 is the perfect solution for you. This versatile product, also known as Evonik Degussa Dynasylan 3403, DOWSIL AY43-062, Shin-Etsu KBM-802, or 3-Mercaptopropyl(dimethoxy)silane, has a wide range of applications in various industries, including coatings, adhesives, sealants, plastics, and rubber.

INNO Specialty Chemicals, a leading manufacturer and supplier of silane coupling agents in China, produces and distributes Degussa Dynasylan 3403 to customers worldwide. This high-quality product is a clear, colorless to yellowish liquid with a sulfur-like odor and a boiling point of 132-134°C. Its chemical formula is C6H16O2SSi, and its molecular weight is 196.34 g/mol.

Degussa Dynasylan 3403 is a bifunctional silane coupling agent that contains both a methoxy group and a mercaptopropyl group. These functional groups enable the silane to react with both inorganic surfaces, such as glass, metal, and ceramics, and organic surfaces, such as polymers, resins, and elastomers. The methoxy group can hydrolyze in the presence of water, forming a silanol group that can bond with the inorganic surface. The mercaptopropyl group can react with the organic surface, forming a covalent bond that can enhance the adhesion between the two surfaces.

The use of Degussa Dynasylan 3403 as a silane coupling agent can provide several benefits to your materials, such as:

1. Improved adhesion: By forming a strong and durable bond between the surfaces, Degussa Dynasylan 3403 can enhance the adhesion of your materials, even in harsh environments.

2. Increased durability: By protecting the surfaces from moisture, corrosion, and other environmental factors, Degussa Dynasylan 3403 can increase the durability and lifespan of your materials.

3. Enhanced mechanical properties: By improving the interfacial strength between the surfaces, Degussa Dynasylan 3403 can enhance the mechanical properties of your materials, such as stiffness, toughness, and fatigue resistance.

4. Better processing: By reducing the viscosity and surface tension of your materials, Degussa Dynasylan 3403 can improve the processing and handling of your materials, such as flowability, wetting, and dispersion.

The applications of Degussa Dynasylan 3403 are numerous and diverse, depending on the specific needs and requirements of your materials. Some of the common applications of Degussa Dynasylan 3403 are:

1. Coatings: By adding Degussa Dynasylan 3403 to your coating formulations, you can improve the adhesion of the coatings to the substrates, such as metals, plastics, and glass. This can also enhance the corrosion resistance, weatherability, and chemical resistance of the coatings.

2. Adhesives and sealants: By incorporating Degussa Dynasylan 3403 into your adhesive and sealant formulations, you can enhance the bonding strength and durability of the adhesives and sealants to the substrates, such as wood, concrete, and rubber. This can also improve the resistance to water, heat, and chemicals of the adhesives and sealants.

3. Plastics and rubber: By using Degussa Dynasylan 3403 as a surface modifier or a crosslinking agent for your plastics and rubber, you can improve the adhesion of the materials to the inorganic surfaces, such as glass fibers, fillers, and reinforcements. This can also enhance the mechanical properties, such as tensile strength, elongation, and modulus, of the plastics and rubber.

4. Others: Degussa Dynasylan 3403 can also be used in other applications, such as textiles, paper, leather, and ceramics, where improved adhesion and durability are required.

In conclusion, Degussa Dynasylan 3403 is a versatile and effective silane coupling agent that can enhance the adhesion and durability of your materials in various applications.
