Plastic drums or stainless steel tank,200kg net weight.
Transportation and Storage
Avoid shine rain and high temperature in transportation.Store the products in cool, shady and ventilated conditions, keep far away from fire.6 months from date of delivery at a maximum storage temperature of 30℃.
General hints
Can burn in fire!Polymerization may be initiated by contamination with peroxides,azo compounds,heavy metal ions,tert.Amines,S compounds.Polymerization is also induced by light.Atomospheric oxygen saturation in the monomer is necessary for stability.Storage temperatures should not exceed 35°C.
