UniCat S 25 is cationic wet end starch, used in the manufacturing of papers/boards to increase the internal
strength properties as well as the retention of fillers and fines.
It has a cationic charge attached to it, which improves the internal strength properties of the paper. The electro kinetic attraction promotes a more intimate contact between the anionic cellulosic fibre surfaces and the starch hydroxyls.
UniCat S 25 can be used to increase the retention of fillers and Finers and to improve sheet strength properties at a low cost. It can be used at a level of 2-10 kg per ton of pulp.
UniCat S 25 can be used for emulsification of AKD/ASA under high agitation. Typical solids of UniCat S 25 are in between.
