As a manufacturer, supplier or factory of specialty chemicals, it is important to stay on top of the latest developments in the industry. One such product that has gained attention in recent years is 1-[3-(Triethoxysilyl)propyl]urea, also known as gamma-ureapropyl triethoxysilane or [3-[Tris(ethoxy)silyl]propyl]urea. This unique compound has a range of applications and benefits that make it a valuable addition to any chemical portfolio.

Properties of 1-[3-(Triethoxysilyl)propyl]urea

1-[3-(Triethoxysilyl)propyl]urea is a colorless to pale yellow liquid that is soluble in water and many organic solvents. It has a boiling point of 310°C and a flash point of 118°C, making it a stable and safe compound to handle. One of the key properties of 1-[3-(Triethoxysilyl)propyl]urea is its ability to react with surfaces containing active hydrogen atoms, such as metals, glass, and ceramics. This makes it useful in a range of applications where adhesion, coupling, or surface modification is required.

Applications of 1-[3-(Triethoxysilyl)propyl]urea

1. Adhesion Promotion

One of the primary applications of 1-[3-(Triethoxysilyl)propyl]urea is as an adhesion promoter. When applied to a surface, the compound reacts with any active hydrogen atoms present, forming strong chemical bonds. This improves the adhesion of coatings, adhesives, and sealants to the surface, making them more durable and reliable. This is particularly useful in applications where the surface is exposed to harsh conditions, such as extreme temperatures, moisture, or chemicals.

2. Surface Modification

Another important application of 1-[3-(Triethoxysilyl)propyl]urea is as a surface modifier. When applied to a surface, the compound forms a thin layer that can improve the surface properties, such as hydrophobicity, oleophobicity, or anti-corrosion. This is particularly useful in applications where the surface needs to resist water or oil, such as in automotive coatings or electronic components.

3. Coupling Agent

1-[3-(Triethoxysilyl)propyl]urea can also be used as a coupling agent in polymer composites. When added to the polymer matrix, the compound forms a chemical bond with the filler particles, improving the adhesion between them. This can improve the mechanical properties of the composite, such as strength, stiffness, and toughness.

4. Crosslinking Agent

Another application of 1-[3-(Triethoxysilyl)propyl]urea is as a crosslinking agent in polyurethane foams. When added to the foam formulation, the compound reacts with the isocyanate groups, forming urea linkages. This can improve the mechanical properties of the foam, such as compression set, tear strength, and resilience.

Availability of 1-[3-(Triethoxysilyl)propyl]urea

1-[3-(Triethoxysilyl)propyl]urea is produced by several manufacturers worldwide, including Evonik Degussa Dynasylan 2201, DOWSIL Z-6676, Shin-Etsu Japan KBE-585, Momentive Silquest A-1160, and Ningbo Inno Pharmchem Co.,Ltd. Each manufacturer may have slight variations in their product specifications, such as purity, viscosity, or color, so it is important to choose the right product for your specific application.

Conclusion

1-[3-(Triethoxysilyl)propyl]urea is a versatile and useful compound that has a range of applications in the chemical industry. As a manufacturer, supplier, or factory, it is important to stay on top of the latest developments in the industry and explore new products that can improve the performance and reliability of your products. With its unique properties and applications, 1-[3-(Triethoxysilyl)propyl]urea is a valuable addition to any chemical portfolio, and can help you stay ahead of the competition.
