SEPLITE® CT821 Catalyst Resin Precautions:
Resins should be stored in sealed containers or bags where temperature was above 0℃ in dry conditions without exposure to direct sunlight.
Do not mix ion exchange resin with strong oxidizing agents; otherwise it will cause violent reactions.
In case of eyes contact with resins, rinse eyes immediately with plenty of water, and consult a specialist. Material and samples must be disposed according to local regulations.
Dry polymers will expand when become wetted and may cause an exothermic reaction. Spilled materials may be slippery.
