The product is N - DODECYLTRIETHOXYSILANE with the CAS number 18536 - 91 - 9. It is factory - supplied and comes with a good price. This silane compound has a chemical formula of C₁₈H₄₀O₃Si. Its molecular weight is approximately 332.6 g/mol. It typically appears as a clear, colorless to light - yellow liquid. The density is around 0.88 - 0.90 g/cm³ at 25°C. It has a boiling point in the range of 240 - 260°C under normal pressure. The flash point is relatively high, usually above 100°C, which indicates a certain degree of safety during storage and handling.
N - DODECYLTRIETHOXYSILANE has a wide range of applications in various industries. In the field of coatings, it can be used as an additive to improve the adhesion of the coating to the substrate. It forms a strong chemical bond between the organic coating and the inorganic substrate, enhancing the durability and weather - resistance of the coating. In the rubber industry, it can act as a coupling agent. By reacting with the rubber matrix and the filler surface, it improves the dispersion of the filler in the rubber, thereby enhancing the mechanical properties of the rubber products, such as tensile strength and tear resistance. In the construction industry, it can be used for the surface treatment of concrete and stone materials. It helps to reduce the water absorption of these materials, improving their anti - freeze and anti - corrosion properties.
When using N - DODECYLTRIETHOXYSILANE, it is important to follow the correct procedures. First, make sure the working environment is well - ventilated. Wear appropriate personal protective equipment, such as gloves and safety glasses. For coating applications, it can be added directly to the coating formulation. The recommended addition amount is usually 1% - 5% of the total weight of the coating. Mix it thoroughly with other components to ensure uniform dispersion. In rubber production, it should be pre - treated with the filler before being added to the rubber compound. This can be achieved by adding it to the filler in a high - speed mixer and mixing for a certain period until a homogeneous mixture is obtained. For surface treatment of construction materials, it can be diluted with an appropriate solvent, and then applied to the surface of the material by brushing, spraying, or dipping methods.
Case 1: Coating on Metal Surface
A manufacturer of metal furniture wanted to improve the adhesion and corrosion resistance of their paint coatings. They added N - DODECYLTRIETHOXYSILANE to their epoxy paint formulation at a ratio of 3%. After the application, the adhesion of the paint to the metal surface was significantly improved. The coating passed the cross - cut test with a rating of 5B, indicating excellent adhesion. In a salt - spray test for 500 hours, the corrosion area of the painted metal was less than 5%, which was much lower than that of the coating without the silane additive.
Case 2: Rubber Tire Production
A tire manufacturer used N - DODECYLTRIETHOXYSILANE as a coupling agent in their tire compound. They first treated the silica filler with the silane in a high - speed mixer. After adding the treated filler to the rubber compound, the dispersion of the silica in the rubber matrix was improved. The tensile strength of the tire increased by 15%, and the tear resistance increased by 20%. The rolling resistance of the tire also decreased by 8%, resulting in better fuel efficiency.
Case 3: Concrete Surface Treatment
In a bridge construction project, the concrete piers needed to be protected from water penetration and corrosion. A solution of N - DODECYLTRIETHOXYSILANE diluted with ethanol was sprayed on the surface of the concrete piers. After treatment, the water absorption of the concrete decreased by 70%. After one year of exposure to the environment, there was no obvious sign of cracking or corrosion on the surface of the concrete piers.
