Cationic water soluble polymer recommended for the efficient neutralisation of the optical brightening effect of fluorescent whitening agents.
It is used for the production of non fluorescent paper from brightened waste paper.
Another important use is during grade changes. It is used to kill fluorescence when changing from whites to colours, or when changing from fluorescent to non fluorescent white grades.
It can be used in brown packaging grades made from waste, to kill the brightener in the waste and reduce dye consumption.
It may be added at the wet end at a suitable addition point. It may be added continuously or batchwise. It can be added to stock or backwater.
The correct addition level must be found by mill trial. It will depend on furnish and machine conditions. Addition level is typically in the region of 1 – 5kg/tonne
