Kraft Paper-cationic Sae Surface Sizing Agent S 660

These Kraft Paper-Cationic SAE Surface Sizing Agent 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 ofLYAR S 660 is 2-5% (active/dry starch), which is roughly equal to 0. 5 a 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 a it retains easily and remains on a surface of the paper/board, especially in applications where the surface size used is an oxidized 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 certain application, the usage ofLYARS 660should also follow the operating instructions of our company.
Safety
LYAR S 660may be stimulated to skin and eyes, it is recommended to use gloves and protective glasses when use. If come into direct contact with eye or skin, immediately rinse with plenty of water at least 15 minutes.
