ANMOCATSIZE-30H is a cationic rosin size designed for efficient sizing in a pH range of 5.0 to 6.5. Anmocatsize 30H is an excellent cationic size rosin with particle size below 2 microns, which actively disperses and imparts excellent internal sizing properties to kraft/paper board/kappa board. Incorporation of an additional charge donor, e.g., cationic starch and/or retention aids, at near neutral pH is beneficial.
In capsize, the alum/PAC consumption is much less than that of dispersed rosin, and thus, the paper can be made at a higher pH.
