The product is 3-Thiocyanatopropyltriethoxysilane with the CAS number 34708-08-2. It is supplied directly from the factory at the best price. This silane coupling agent has a unique chemical structure that combines a thiocyanate group and a triethoxysilyl group.
The chemical formula of 3-Thiocyanatopropyltriethoxysilane is C₁₀H₂₃NO₃SSi. It has a molecular weight of approximately 265.44 g/mol. Physically, it is typically a clear to slightly yellowish liquid. The boiling point of this compound is around 278 - 279 °C, and it has a density of about 1.01 - 1.03 g/cm³ at 25 °C.
3-Thiocyanatopropyltriethoxysilane has a wide range of applications across different industries. In the rubber industry, it can be used as a coupling agent to improve the adhesion between inorganic fillers (such as silica) and rubber matrices. This leads to enhanced mechanical properties of rubber products, including improved tear strength, abrasion resistance, and low - rolling resistance in tires.
In the coating industry, it can be added to coatings to improve their adhesion to various substrates, especially those made of glass, metal, or ceramics. This results in more durable and high - performance coatings that are resistant to peeling and corrosion.
In the plastics industry, it can be used to modify the surface properties of plastic materials. It can improve the compatibility between different polymer phases and inorganic fillers, thereby enhancing the overall performance of plastic products.
When using 3-Thiocyanatopropyltriethoxysilane, it is important to follow proper safety procedures. Wear appropriate personal protective equipment, such as gloves and goggles, to avoid direct contact with the skin and eyes.
In most applications, the product is added during the mixing or compounding process. For example, in the rubber industry, it can be added to the rubber compound along with other ingredients such as fillers, accelerators, and vulcanizing agents. The recommended dosage usually ranges from 1 - 5% by weight of the filler, depending on the specific application and the desired performance.
In the coating industry, it can be added to the coating formulation during the blending process. It is important to ensure thorough mixing to achieve uniform dispersion of the silane coupling agent in the coating.
Caso 1: Fabrico de pneus
A tire manufacturer was looking to improve the performance of their tires. They added 3-Thiocyanatopropyltriethoxysilane to their silica - filled rubber compound. After testing, they found that the tear strength of the tires increased by 20%, and the rolling resistance decreased by 15%. This not only improved the fuel efficiency of vehicles using these tires but also extended the service life of the tires.
Case 2: Coating on Metal Substrates
A metalworking company wanted to enhance the corrosion resistance of their metal products. They incorporated 3-Thiocyanatopropyltriethoxysilane into their epoxy - based coating. The coated metal samples were subjected to salt - spray testing. The results showed that the coating with the silane coupling agent had significantly better corrosion resistance compared to the coating without it. After 500 hours of salt - spray testing, the coating with the silane coupling agent showed only minor signs of corrosion, while the coating without it had extensive rusting.
