Marking, Packing, Storage and Transportation:

1) The packing container should have obvious mark including: manufacturer, address, date of production, net weight, standard No., inflammable and explosive product (GB190-90) and heatproof mark (GB191-90).

2) The packing container adopts clean and dry tanker or 200kg/galvanized barrel (if the environmental temperature is higher than 30° C, must use tanker). The container must be firmly sealed and hasn't been stored other chemicals. Use nitrogen gas to displace for container before packing, and leave 20% space. If the environmental temperature is higher than 28° C, the container should have anti-solarization facilities.

3) It is a dangerous product, handle with care during loading, unloading and transportation. Not to frictionize, impact and weigh down them. Not to pack together with other inflammable and explosive matters.

If the storage temperature is lower than 0° C, please use nitrogen gas to protect and add into appropriate amount of polymerization inhibitor.
