As an accredited Hexamethyldisiloxane factory, we enforce strict quality protocols—every batch undergoes rigorous testing to ensure consistent efficacy and safety standards.
| Packing | Hexamethyldisiloxane is packaged in a 1-liter amber glass bottle with a secure screw cap and tamper-evident seal. |
| Shipping | Hexamethyldisiloxane should be shipped in tightly sealed containers, away from heat, sparks, and open flames. It must be labeled as a flammable liquid and handled according to relevant safety regulations. Transport in accordance with local, national, and international guidelines, such as UN1993 (Flammable Liquid, N.O.S.), using appropriate hazard labels. |
| Storage | Hexamethyldisiloxane should be stored in a tightly sealed container in a cool, dry, and well-ventilated area, away from direct sunlight, heat sources, and ignition sources. Keep away from strong oxidizing agents and acids. Proper labeling and secondary containment are recommended to prevent leaks or spills. Store at ambient temperature and ensure compliance with all relevant safety regulations and guidelines. |
