Grade: CG-801

Triethoxyoctylsilane

CG-801 (Triethoxyoctylsilane) has three ethoxy groups that easily hydrolyze to form Si-OH structures. This monofunctional silane can modify the surface of glass, quartz sand, metals, and powder fillers to provide good hydrophobic properties, and can also improve the compatibility between fillers and resins.

Packaging and Storage

This product can be packaged in 25 kg plastic drums, 200 kg plastic drums, or steel drums. Other package sizes are available upon request. Store in a cool, well-ventilated, dry place in tightly sealed containers, protected from light. Keep away from moisture and sources of ignition. Ensure the lid is tightly sealed and effectively isolates the product from air; moisture in the air can react quickly, thereby leading to hydrolysis and polymerization. Shelf life in the original unopened packaging is one year. This product is irritating to skin and eyes. If it contacts skin, wash with soap. If it contacts eyes, rinse immediately with plenty of water.

Application

  • CG-801 can modify the surface of precipitated silica and reduce its viscosity, while also improving the processability of rubber compounds containing precipitated silica fillers.

  • CG-801 can modify the surface of glass, quartz sand, metals, and powder fillers to provide good hydrophobic properties.

  • CG-801 can improve the compatibility between fillers and resins.

  • CG-801 can be used in the tire, footwear, and mechanical rubber industries to improve the dispersibility of silica.

  • CG-801 can be used as an additive for cement concrete to effectively improve the impermeability performance of cement buildings and dams.
