3-Chloropropyltriethoxysilane CAS No. 5089-70-3
3-Chloropropyltriethoxysilane CAS No. 5089-70-3 (CPTS) is a clear, colorless, flammable liquid with a mild odor. It is a silane coupling agent that is used to modify the surface properties of materials. CTPS is a versatile reagent that can be used in a variety of applications, including:
- Adhesion promoters
- Mold release agents
- Water repellents
- Anti-static agents
- Corrosion inhibitors
- Textile finishes
- Paper coatings
- Cosmetics
- Pharmaceutical products
CTPs is a safe and effective reagent when used as directed. However, it is important to note that it is a flammable and irritant. It should be stored in a cool, dry place and away from heat and ignition sources. If it comes into contact with the skin or eyes, it should be washed immediately with soap and water.
Characteristics and uses:
The appearance of this product is a colorless transparent liquid. It is an important organosilane coupling agent intermediate, which can be used as a filler reinforcing agent for synthetic resins, and can also be used to improve the chemical link between resin and organic materials, and is also an important raw material for the production of downstream silane coupling agents containing ethoxy groups.
Packaging and storage:
- This product must be sealed and stored in a warehouse with a room temperature of about ≤30 °C, otherwise it will be hydrolyzed by moisture to form polymers.
- This product has slight irritation to the skin and eyes, so it is necessary to protect it when using it.
- The packaging of this product is divided into: 200KG plastic packaging drum and 1000KG plastic drum packaging.
