SAE Anionic Surface Sizing Agent LY-S661

Anionic Surface Sizing Agent LY-S661 ISO9001:2008 Certified Company High Stability & Low Tendency to Foam

General Information 

LY® S 661 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 661 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 anionic – 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.

As an anionic product, in the applications with OBA, it will not cause OBA invalid, can be added directly.  

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.
