PRODUCT INFORMATION
SEPLITE® Monojet™SC7900N H
Nuclear grade, Uniform particle size, Gel, Strong acid cation resin for water treatment in Nuclear power industry
SEPLITE® Monojet™ SC7900N H Ion Exchange Resin is an extremely high-purity, high-capacity with 16% DVB cation resin in uniform particle size designed specifically for use in nuclear power industry to remove cations for purification and control the pH value.
This resin is supplied in H form and the ionic conversion rate of H form is up to 99%. There's special procedure imposed during the manufacturing in order to assure the highest demand of purity. The uniform particle size gives an optimized balance of pressure drop and exchange kinetics.
When used in a mixed bed, it always paired with SA8800N OH anion exchange resin.
The resin can be used in primary water treatment, fuel pool purification and PWR steam generation blowdown, also can be used in BWR condensate polishing application.

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.
