    Packing & Storage
    Packing Tetramethoxysilane is packaged in a 500 mL amber glass bottle with a tamper-evident cap and UN hazard labeling.
    Storage Tetramethoxysilane should be stored in a tightly sealed container in a cool, dry, and well-ventilated area. Keep it away from moisture, humidity, acids, and sources of ignition. Store it separately from oxidizing agents and strong bases. Ensure appropriate chemical labeling and containment to prevent leaks or spills, and use appropriate safety measures to avoid inhalation or skin contact.
    Shipping Tetramethoxysilane should be shipped in tightly sealed containers made of compatible material, protected from moisture. It is typically classified as a flammable liquid and transported according to relevant hazardous material regulations. Ensure labels indicate chemical hazards, and use secondary containment. Handle with care to prevent leaks, spills, or exposure during transit.
