Precautions

• Store resins in sealed containers or bags at temperatures above 0℃ in dry conditions, away from direct sunlight.
• Do not mix ion exchange resin with strong oxidizing agents.
• In case of eye contact, rinse immediately with plenty of water and consult a specialist.
• Dispose of materials and samples according to local regulations.
• Dry polymers will expand when wetted, potentially causing an exothermic reaction.
• Spilled materials may be slippery.
