Cartarex NT is capable of helping to significantly eliminate unwanted fluorescence in paper with nearly no yellowing effect. Its effectiveness extends to the disulpho class of optical brightening agents (OBAs) which are recognized as being very resistant to quenching. This capability puts it at the forefront of fluorescence-quenching performance throughout water circulation and stock preparation equipment when changing from a brightened paper to a non-brightened grade.
Papermakers can also take advantage of production time-savings and cost benefits thanks to Cartarex NT’s high effectiveness. Its rapid quenching and resulting minimal impact on system runnability lead to considerably shorter changeover times, allowing an increase in production output and efficiency.
