General product information:
Surface sizing products are designed to enhance the surface properties of various paper and board grades. They reduce the needs of internal sizing requires to achieve a desired overall sizing level, thus resulting in a cleaner wet end and improving machine runnability. This surface sizing products are compatible with most conventional surface application techniques and can be applied at the size press together with a starch solution. They will not increase the viscosity of the size press solution and are compatible with a wide range of other size press additives, including fluorescent whitening agents, dyes, most pigment dispersions, and non-ionic or anionic auxiliary chemicals.
Application:
This Surface Sizing Agent is newly developed by our company. Compared with normal Surface Sizing Agent in the market, this Surface Sizing Agent has small reliance on Aluminum Sulfate. You can add less Aluminum Sulfate, or even no Aluminum Sulfate. Combined with cationic starch, it can greatly improve the water-resistance of paper, therefore it can improve the surface strength of paper.
The actual dosage depends on your expected Cobb value and your pulp. When using waste paper pulp, for the sake of saving cost, you can add proper Aluminum Sulfate. Please avoid being contacted with strong anionic materials.
