The CAS number serves as a unique identifier for this chemical, ensuring its accurate recognition in various chemical databases and industries.
Trimethoxysilylpropanethiol has a specific molecular structure that contributes to its unique chemical properties. It contains a thiol group (-SH) and a trimethoxysilyl group (-Si(OMe)₃), which endow it with the ability to react with a wide range of substances. In terms of physical properties, it typically appears as a clear liquid under normal conditions. Its purity can usually be adjusted according to different industrial requirements, with high - purity products meeting strict quality standards.
2.1 Rubber Industry: In the rubber industry, trimethoxysilylpropanethiol is used as a coupling agent. It can improve the bonding between inorganic fillers (such as silica) and rubber polymers. This leads to enhanced mechanical properties of rubber products, including better abrasion resistance, tear strength, and reduced rolling resistance. As a result, it is widely used in the production of high - performance tires, conveyor belts, and rubber seals.
2.2 Adhesive and Sealant Industry: In adhesives and sealants, this compound can act as an adhesion promoter. It helps to improve the adhesion between different substrates, such as metals, glass, and plastics. This makes it suitable for applications in the automotive, construction, and electronics industries, where strong and durable bonding is required.
2.3 Surface Treatment: It can be used for surface modification. By reacting with the surface of materials, it can change the surface energy and chemical properties of the materials, improving their wettability, corrosion resistance, and anti - fouling properties. This is useful in the coating industry for preparing high - performance coatings.
3.1 Storage: Store the product in a cool, dry place away from direct sunlight and heat sources. It should be kept in a well - sealed container to prevent moisture and air from entering, which may cause degradation of the product.
3.2 Handling: When handling trimethoxysilylpropanethiol, appropriate personal protective equipment (PPE) should be worn, including gloves, safety glasses, and a lab coat. Avoid direct contact with skin, eyes, and clothing. In case of contact, immediately rinse with plenty of water and seek medical attention if necessary.
3.3 Dosage: The dosage of the product depends on the specific application. In the rubber industry, the typical dosage is usually in the range of 1 - 5% based on the weight of the filler. In adhesive and sealant formulations, the dosage may vary according to the type of substrates and the required adhesion strength. It is recommended to conduct small - scale tests before large - scale production to determine the optimal dosage.
4.1 Tire Manufacturing: A tire manufacturer was facing challenges in achieving good dispersion of silica in the rubber matrix, which led to poor tire performance. After using trimethoxysilylpropanethiol as a coupling agent, the dispersion of silica was significantly improved. The resulting tires showed a 15% increase in abrasion resistance and a 10% reduction in rolling resistance. This not only enhanced the product quality but also reduced fuel consumption for vehicles using these tires.
4.2 Electronic Device Sealing: An electronics company needed a high - performance sealant for its electronic devices to protect them from moisture and dust. By incorporating trimethoxysilylpropanethiol into the sealant formulation, the adhesion between the sealant and the plastic housing of the devices was greatly improved. The sealant passed strict environmental tests, ensuring the long - term reliability of the electronic devices.
