Applications

Application	Details
Curing Agent	Used primarily as a curing agent for unsaturated polyester resins, it provides shorter gel times and lower heat peaks compared to methyl ethyl ketone peroxide. Particularly suitable for manufacturing thick molded products, buttons, and spray molding processes. Requires cobalt-based accelerators for ambient temperature curing.

Packaging and Transportation

Item	Details
Standard Packaging	20 kg PE plastic drums, custom packaging available based on user requirements.
Transport Regulations	Conforms to IMDG 5.2, UN No. 3105 (Class 5.2 Liquid Organic Peroxide, Type D).

Shelf Life

Shelf Life (Storage Conditions)	Details
Shelf Life	Product quality guaranteed for 3 months if stored according to manufacturer instructions.

Storage Instructions

Precaution	Description
Storage Temperature	Store at temperatures not exceeding 25°C.
Storage Environment	Keep packaging sealed and in a well-ventilated area. Avoid exposing to reducing agents, acids, alkalis, and heavy metal compounds (e.g., accelerators, metal soaps). No handling in storage areas.

Fire Protection

Fire Protection	Description
Small Fire Handling	Use dry powder or CO₂ extinguishers. Apply large amounts of water to prevent re-ignition.
Large Fire Handling	For large fires, use a large water stream from a safe distance.
