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:
Miracle’s surface sizing products are effective over a wide pH range and are fully cured on-machine, provided that modest heat is applied to the treated paper during drying. This kind of Surfaces Sizing Agent is synthesized by copolymerization of styrene and ester. It can efficiently combine with starch result with good cross link intensity and hydrophobic properties. With lower dosage, lower cost and easy use advantages, it has good film-forming and strengthening property to writing paper, copy paper and other fine papers. It can be used with starch to reduce sizing cost. It also has good mechanical stability with less bubbles generated during the operational process.
Completely replace the usage of internal sizing agent. Application temperature should be below 75℃.
Packing & storage:
Packing: 200kg OR 1000kg plastic drums.
Storage: This product should be stored in the drying room. Avoid light, sun and freezing. Temperature should below 30℃.
