Packaging
Typically supplied in 25 kg PE drums for safe storage and handling, but other packaging options can be arranged to meet specific customer requirements.
-
Storage
Store in an area with proper ventilation, tightly sealed to prevent contamination. The maximum storage temperature should not exceed 25°C, and avoid exposure to incompatible chemicals such as acids, alkalis, heavy metal compounds (accelerators and metallic soaps). Repacking or transferring the product in storage areas is not recommended.
-
Storage Stability
If stored correctly, this chemical compound retains its quality for up to three months under the conditions specified by the manufacturer.
-
Safe Handling
Keep the product away from open flames, heat sources, and ignition points to ensure safety during handling and storage.
Avoid contact with incompatible chemicals like reducing agents (amines), acids, bases, and heavy metal compounds (such as accelerators, metallic soaps).
Refer to the Material Safety Data Sheet (MSDS) for detailed safety guidelines and handling instructions.
