Packaging and Storage
This product can be packaged in 25 kg plastic drums, 200 kg plastic drums, or steel drums. Other package sizes are available upon request. Store in a cool, well-ventilated, dry place in tightly sealed containers, protected from light. Keep away from moisture and sources of ignition. Ensure the lid is tightly sealed and effectively isolates the product from air; moisture in the air can react quickly, thereby leading to hydrolysis and polymerization. Shelf life in the original unopened packaging is one year. This product is irritating to skin and eyes. If it contacts skin, wash with soap. If it contacts eyes, rinse immediately with plenty of water.
