Cationic Direct Dyestuff
Levacell / Pontamine Fast Blue KS-6GLL liquid is a highly substantive dyestuff which is used whenever rapid exhaustion onto the paper furnish is required.
It can be added shortly before the flow box, for example, and still be taken up completely, thanks to its high affinity to the pulp. Being a cationic direct dyestuff, Levacell / Pontamine Fast Blue KS-6GLL liquid is incompatible with anionic Levacell / Pontamine brands if mixed directly with them. Anionic and cationic direct dyestuffs should not be mixed or added at the same metering point.
The Pontamine name is used in North America.
