n Attention:
Ø Avoid exposure to heat sources such as direct sunlight or steam pipes. Stored in a dry place at temperatures below 25℃ and the shelf life is 6 months.Keep sealed to prevent moisture pick-up and monomer loss.
Ø Transportation should fit the State Council “Chemistry Dangerous Articles Safety Management Regulations”. Because it contains styrene monomer, it is hazardous and inflammable.
