High Content, High Effeciency

2,2-Dibromo-3-Nitrilopropionamide (DBNPA) is a quick-kill biocide that easily hydrolyzes under both acidic and alkaline conditions. It is preferred for its instability in water as it quickly kills and then quickly degrades to ammonia and bromine ions. DBNPA acts similar to the typical halogen biocides.


DBNPA is used in papermaking as a preservative in paper coating and slurries. It is also used as slime control on papermachines.

High Stability & Low Tendency to Foam

General Information 

LY® S 660 is a styrene-acrylate copolymer dispersion with low viscosity. It shows high stability towards chemical and mechanical influences and a low tendency to foam.

The common adding point is within surface sizing system, the inlet of starch transfer pump or size service tank is the best option for addition.

 

Application 

The typical dosage of LY® S 660 is  2-5% (active/dry starch), which is roughly equal to 0.5 – 1.7 kg/paper ton. The product is a dispersion polymer and it is not sensitive to pH variations. Anti- foaming agent is not usually needed. The product is cationic – it retains easily and remains on a surface of the paper/board, especially in applications where the surface size used is an oxidised or entzymaticly converted starch. However, the care must be taken in the applications, in which high amounts of optical agents are used in a surface size. The product is not, due to the cationic charge, compatible with anionic optical brighteners.

For each different machine, need optimize the amount of the surface sizing agent to get the best sizing results. Lanya's technical services team can help you achieve this goal.
