Cationic starch carries a positive charge over the entire pH range creating their affinity towards negatively charged substrates, such as cellulose, pulp and some synthetic fibres, aqueous suspensions of minerals and slimes and biologically active macromolecules.
This starch may be derived from either maize or tapioca is used primarily as a wet-end starch and mainly used in paper and cardboard forming processes:
-Increases mechanical strength and for better retention of fines and fillers
-Enables faster drainage and improved sheet formation and production, saving both time
and resources.
-Improves opacity, brightness and stiffness of paper and allows for better printing quality
-It is also popularly used in the manufacture of disposable diapers (nappies) and personal
sanitary products.
