Silane coupling agents are widely used in the chemical industry due to their unique properties that enable them to enhance the performance of various materials. One such silane coupling agent is 3-ureidopropyltriethoxysilane, which is commonly known as Dynasylan 2201, Z-6676, KBE-585, Silquest A-1160, and other names. This article will provide an overview of the properties, applications, and benefits of 3-ureidopropyltriethoxysilane, highlighting INNO Specialty Chemicals as the leading manufacturer and supplier of this product from China.
Properties of 3-Ureidopropyltriethoxysilane
3-Ureidopropyltriethoxysilane is a clear, colorless liquid with a molecular formula of C11H26N2O3Si and a molecular weight of 266.42 g/mol. It has a boiling point of 266 °C and a flash point of 115 °C. The silane coupling agent contains a urea functional group and three ethoxy groups, which make it highly reactive with various organic and inorganic substrates. 3-Ureidopropyltriethoxysilane has a density of 0.978 g/mL and a viscosity of 2.5 cP at 25 °C. It is soluble in most organic solvents, such as ethanol, acetone, and toluene, but insoluble in water.
Applications of 3-Ureidopropyltriethoxysilane
3-Ureidopropyltriethoxysilane is a versatile silane coupling agent that finds applications in various industries, including adhesives, coatings, sealants, composites, plastics, rubber, textiles, and construction. The main function of 3-ureidopropyltriethoxysilane is to improve the adhesion, wetting, dispersibility, and durability of the materials it is added to. The urea functional group of the silane coupling agent can react with the hydroxyl groups of the substrate surface, forming covalent bonds and creating a strong interfacial adhesion. The ethoxy groups of the silane coupling agent can hydrolyze in the presence of moisture, forming silanol groups that can further condense with other silanol groups or with the substrate surface, creating a three-dimensional network that enhances the mechanical and chemical properties of the material.
Some specific applications of 3-ureidopropyltriethoxysilane are:
- Adhesives: 3-Ureidopropyltriethoxysilane can improve the adhesion of various types of adhesives, such as epoxy, polyurethane, acrylic, and phenolic, to metals, glass, ceramics, and plastics. It can also enhance the water resistance, heat resistance, and aging resistance of the adhesives.n- Coatings: 3-Ureidopropyltriethoxysilane can act as a crosslinker and a dispersant in coatings, improving the hardness, scratch resistance, and pigment dispersion of the coatings. It can also provide anti-corrosion and anti-fouling properties to the coatings.n- Rubber: 3-Ureidopropyltriethoxysilane can be used as a coupling agent and a crosslinker in rubber compounds, enhancing the bonding between the rubber and the filler, such as carbon black or silica, and improving the mechanical properties, such as tensile strength, tear resistance, and abrasion resistance, of the rubber.n- Textiles: 3-Ureidopropyltriethoxysilane can be applied to textile fibers, such as cotton, polyester, and nylon, to impart water repellency, oil repellency, and stain resistance. It can also improve the dyeability and the anti-static properties of the textiles.n- Construction: 3-Ureidopropyltriethoxysilane can be added to cement, concrete, and mortar to enhance the adhesion to the substrate, reduce the water absorption, and improve the freeze-thaw resistance and the durability of the construction materials.
Benefits of 3-Ureidopropyltriethoxysilane
The use of 3-ureidopropyltriethoxysilane in various applications can bring several benefits, such as:
- Improved adhesion: 3-Ureidopropyltriethoxysilane can create a strong interfacial adhesion between the substrate and the material, resulting in better bonding and less delamination or detachment.n- Enhanced durability: 3-Ureidopropyltriethoxysilane can improve the resistance of the material to various environmental factors, such as water, heat, UV radiation, and chemical agents, resulting in longer service life and less maintenance.n- Better processing: 3-Ureidopropyltriethoxysilane can improve the processability of the material, such as the dispersion of fillers, the flowability of coatings, and the curing of adhesives, resulting in higher efficiency and lower costs.n- Environmentally friendly: 3-Ureidopropyltriethoxysilane is a low-toxicity and low-VOC substance that can contribute to the sustainability of the products and the environment.
