Tulsimer ® T-46 Li is a specially developed premium grade strongly acidic cation exchange resin containing nuclear sulphonic acid groups with excellent physical and chemical stability for use in the nuclear industry.

Tulsimer ®T-46 Li is primarily used for purification of reactor coolant water and moderator in nuclear power station plants to keep corrosion products to the minimum and thus protect the heat transfer surfaces from scaling and corrosion.

Tulsimer ® T-46 Li is supplied in hydrogen, lithium and ammonium forms to facilitate control of the pH of coolant water at a value that would result in practically negligible attach on metal surface by the coolant water.

Tulsimer ® T-46 Li is manufactured under the most stringent quality controls to ensure minimal metallic impurities esulting in the highest purity of the ionic form supplied.
