As an accredited Hexamethyldisilazane factory, we enforce strict quality protocols—every batch undergoes rigorous testing to ensure consistent efficacy and safety standards.
| Packing | Hexamethyldisilazane, 500 mL, is packaged in a sealed amber glass bottle with a plastic screw cap and safety label. |
| Shipping | Hexamethyldisilazane is shipped in tightly sealed, corrosion-resistant containers under dry, inert conditions to prevent moisture contact, as it is highly flammable and reacts with water. The containers are clearly labeled, complying with hazardous materials regulations, and proper ventilation is ensured during transport to prevent vapor accumulation and potential hazards. |
| Storage | Hexamethyldisilazane should be stored in a tightly closed container, in a cool, dry, and well-ventilated area, away from heat, sparks, open flames, and incompatible substances such as oxidizers and acids. Protect from moisture and direct sunlight. Use only in fume hoods and ensure proper labeling. Store away from sources of ignition, as it is flammable and volatile. |
