Packaging: Plastic drums or stainless steel tank，200kg net weight. Transportation and Storage: 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℃.
