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.
