III. Packaging, Transportation, and Storage1. Packed in 200L plastic drums, with a net weight of 190 kilograms per drum.
2. This product is not classified as dangerous goods, but it is flammable. It should be stored and transported away from sources of ignition.
3. This product undergoes self-polymerization during storage, leading to a decrease in acid value, which accelerates during hot seasons. Therefore, this product should be stored in a sealed and shady place, with an effective storage period of three months. If it exceeds the storage period and passes inspection, it can still be used.
