As an accredited Butyltrichlorosilane factory, we enforce strict quality protocols—every batch undergoes rigorous testing to ensure consistent efficacy and safety standards.
| Packing | Butyltrichlorosilane is packaged in a 500 mL amber glass bottle, tightly sealed with a PTFE-lined cap, and labeled hazardously. |
| Shipping | Butyltrichlorosilane should be shipped in tightly sealed, corrosion-resistant containers, under a dry, inert atmosphere to prevent hydrolysis and hazardous reactions. Transport according to UN 2987 regulations for toxic, flammable liquids, Class 6.1, Packing Group II. Clearly label with hazard markings and ensure compliance with all relevant safety and regulatory guidelines. |
| Storage | Butyltrichlorosilane should be stored in a cool, dry, well-ventilated area away from moisture, heat, and sources of ignition. The chemical must be kept in tightly closed, clearly labeled containers made of compatible materials—preferably glass or stainless steel. Avoid contact with water or humid air, as it reacts violently with moisture and can release toxic and corrosive gases such as hydrogen chloride. |
