High Quality Phenyltriethoxysilane with CAS number 780 - 69 - 8 is a key chemical compound in various industries. Its molecular formula is C₁₂H₂₀O₃Si, and the molecular weight is approximately 240.37 g/mol. It has a clear to slightly yellowish liquid appearance. This product features excellent chemical stability, high purity, and is known for its optimal price - performance ratio in the market.
It is soluble in common organic solvents such as toluene, xylene, and ethanol. The boiling point of Phenyltriethoxysilane is around 232 - 235°C, and the density is about 0.99 - 1.01 g/cm³ at 25°C. The refractive index is approximately 1.468 - 1.472. These physical and chemical properties play a crucial role in determining its usability in different applications.
1. **Adhesives and Sealants**: Phenyltriethoxysilane can be used as a coupling agent in adhesives and sealants. It can improve the adhesion between organic polymers and inorganic substrates, such as glass, metal, and ceramics. This enhances the strength and durability of the bond, making it suitable for applications in construction, automotive, and electronics industries.
2. **Coatings**: In the coatings industry, it acts as an additive to improve the weather resistance, chemical resistance, and adhesion of the coatings. It can react with the surface of the substrate and form a strong chemical bond, preventing the coating from peeling or cracking over time.
3. **Composites**: As a reinforcement agent in composite materials, it can enhance the interface between the fiber and the matrix. This results in improved mechanical properties of the composites, such as higher strength, stiffness, and impact resistance. It is widely used in the production of aerospace components, sports equipment, and automotive parts.
1. **Dilution**: If necessary, Phenyltriethoxysilane can be diluted with an appropriate organic solvent. The dilution ratio should be determined according to the specific application requirements. Generally, a dilution ratio of 1 - 10% in a suitable solvent is common.
2. **Surface Treatment**: For applications in adhesion and coating, the substrate surface should be clean and dry before using the product. Phenyltriethoxysilane can be applied to the surface by spraying, brushing, or dipping. After application, the surface should be allowed to dry at room temperature or under suitable curing conditions.
3. **Mixing in Composites**: In composite production, it can be added to the resin matrix during the mixing process. The amount of addition depends on the type of resin, fiber, and the desired properties of the composite. It is recommended to conduct small - scale tests first to determine the optimal dosage.
1. **Automotive Adhesive Application**: A leading automotive manufacturer was facing issues with the adhesion of a new type of plastic trim to the metal body of the vehicle. By using Phenyltriethoxysilane as a coupling agent in the adhesive, the adhesion strength increased by 30%. This not only improved the quality of the final product but also reduced the number of warranty claims related to trim detachment.
2. **Coating for Outdoor Furniture**: A furniture manufacturer was looking for a way to improve the weather resistance of their outdoor wooden furniture coatings. After adding Phenyltriethoxysilane to the coating formulation, the coating showed significantly better resistance to UV radiation, moisture, and temperature changes. The furniture maintained its appearance and integrity for a much longer time, leading to increased customer satisfaction.
3. **Carbon Fiber Composite in Aerospace**: An aerospace company was developing a new carbon fiber composite component. By incorporating Phenyltriethoxysilane in the resin matrix, the strength - to - weight ratio of the composite increased by 20%. This allowed the component to meet the strict weight and performance requirements of the aerospace industry, resulting in improved fuel efficiency and overall performance of the aircraft.
