CUP is classified as a Class F liquid organic peroxide; cargo classification: 5.2, UN Number: 3109, Class 2 dangerous goods packaging.
Safety Precautions:
(1) Keep away from sources of ignition, open flames, and heat sources.
(2) Avoid contact with reducing agents (such as amines), acids, alkalis, and heavy metal compounds (such as accelerators, metal soaps, etc.)
(3) Please refer to the Material Safety Data Sheet (MSDS) for this product.
Applications:
CUP is a commonly used polymerization initiator. It can be widely used in various polymerization reactions, such as suspension polymerization and emulsion polymerization. It can also form an oxidation-reduction system with accelerators to
facilitate polymerization reactions at room temperature.
Storage Conditions:
Keep the packaging tightly sealed and store in a well-ventilated area. The maximum storage temperature is 40°C. Avoid contact with reducing agents such as amines, acids, bases, and heavy metal compounds (accelerators and metal soaps). Repackaging and handling within the
warehouse are strictly prohibited.
Storage Stability:
When stored under the conditions specified by the manufacturer, the product is guaranteed to meet factory technical standards for three months.
Fire Extinguishing:
For small fires, use dry powder or carbon dioxide fire extinguishers, while simultaneously spraying with copious amounts of water to prevent reignition. For large fires, spray with copious amounts of water from a safe distance.
