General product information:
ASA is a reactive neutral sizing agent with high efficiency and activity, which can easily react with fiber to form ester bond. It doesn’t require any heat treatment or curing time when away from the paper machine. No paper slipping is caused due to its low friction coefficient. Therefore, it is suitable for high-speed paper machines, particularly for the paper made from waste paper. The system influence and the sizing cost is also very low.
Application:
Due to the instability of ASA emulsion, it must be on-line emulsification and used immediately after preparation. The cationic starch or cationic polymer are often used as emulsifier and protectant to prevent hydrolysis.
Packing & storage:
Packing: 200kg OR 1000kg plastic drums.
Storage: Avoid high temperature and solarization, and prevent from dampness. The store temperature should be 10℃-35℃, keep ventilate.
