3-Chloropropyltriethoxysilane, with the CAS number 5089-70-3, is a high - quality chemical product offered at the best price. Its chemical formula is C₉H₂₁ClO₃Si. It is a colorless to light - yellow clear liquid with a characteristic odor. The boiling point of this compound is around 222 - 224 °C, and its density is approximately 0.99 g/cm³ at 25 °C. This product has a refractive index of about 1.426 at 20 °C.
3 - Chloropropyltriethoxysilane has a wide range of applications in various industries. In the field of adhesives and sealants, it can be used as a coupling agent. It helps to improve the bonding strength between inorganic materials (such as glass, metal, and ceramic) and organic polymers by forming a chemical bridge between them. This results in better adhesion, water resistance, and durability of the adhesives and sealants.
In the rubber industry, it is used as a surface modifier for fillers. When added to rubber compounds, it can improve the dispersion of fillers like carbon black and silica, enhancing the mechanical properties of the rubber, such as tensile strength, tear resistance, and abrasion resistance. In the paint industry, it can be used to improve the adhesion of paints to substrates, and also enhance the chemical resistance and weatherability of the painted surfaces.
When using 3 - Chloropropyltriethoxysilane, it is important to follow proper safety procedures. Wear appropriate personal protective equipment, such as gloves, goggles, and a lab coat. This product should be used in a well - ventilated area to avoid inhalation of its vapors.
For use as a coupling agent in adhesives, it can be directly added to the adhesive formulation during the mixing process. The recommended dosage usually ranges from 0.5% to 3% by weight, depending on the specific application and the type of materials being bonded. When used as a filler modifier in rubber, it can be pre - treated with the filler or added during the rubber compounding process. The amount added also depends on the type and amount of filler used, typically around 1% - 5% by weight of the filler.
Case 1: Adhesive for Glass - Metal Bonding
A company was facing issues with the poor adhesion of an adhesive used to bond glass and metal components in an electronic device. After adding 3 - Chloropropyltriethoxysilane at a dosage of 1.5% by weight to the adhesive formulation, the bonding strength increased significantly. In a shear strength test, the bonded samples showed a 30% improvement in strength compared to the samples without the silane. The bonded joints also passed the humidity and temperature cycling tests, indicating better durability.
Case 2: Modified Rubber for Tire Treads
A tire manufacturer wanted to improve the performance of their tire tread rubber. By adding 3 - Chloropropyltriethoxysilane at a dosage of 2% by weight of the silica filler during the rubber compounding process, they were able to improve the dispersion of silica in the rubber matrix. The resulting tire tread rubber showed a 20% increase in abrasion resistance and a 15% improvement in wet grip performance, which is crucial for tire safety.
