Surface Sizing Agent S660 CAS NO.24981-13-3

Surface Sizing Agent LY® S 660

 

GENERAL INFORMATION

LY®S 660 is a kind of styrene-acrylic emulsion surface sizing agent, used on paper and paper board’s surface sizing in variety of papermaking conditions. Compared with AKD kind of surface sizing agent, LY®S 660 almost has no problems such as maturation period, which can effectively control the quality of the paper sizing. Besides, LY®S 660 has a low tendency to foam, it can increase the paper surface strength to a certain extent. This product can partly replace internal sizing, purifying the wet system.

 

APPLICATION

The common adding point of LY®S 660 is within surface sizing system, the inlet of the starch transfer pump or being directly added into the used bucket of sizing material. The typical dosage is 2～5%(dry starch), which is roughly equivalent to 0.5～2.0 kg/t paper ton. Basically, it need aluminum sulfate to help the sizing. It should be noticed that LY® S 660 can not be directly added in the application of OBA, which to prevent the failure of OBA.

For different paper machines, the dosage of surface sizing agent should be optimized in order to obtain the best sizing effect. Lanya’ technical service team can help you achieving this goal.
