Applying :
Brightening during paper compounding:
To add it into pulp directly or after dissolved before using alum and cationic auxiliary. It has mid to high affinity to fiber. The brightness will be affected by dyeing time and consistence of the pulp. When the consistence of the pulp is the highest, the brightness will be the best.
Dosage:
To dry pulp: 0.15~0.4%, max dosage<0.6%.
