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.

Application

Cationic wet end starch 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.

Cationic wet end starchcan be used for emulsification of AKD/ASA under high agitation. Typical solids of Cationic wet end starch are in between 2-6%.
