Surface sizing agent is designed to enhance the surface properties of various
paper and board grades. It can 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. It will not increase the viscosity of the size
press solution and is 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. Solid Surface Sizing
Agent is a new type of surface sizing agent, and can efficiently combine with
starch result good cross link intensity and hydrophobic properties. With lower
dosage, lower cost and easy use advantages, it has good film-forming
property which can significantly improve the water resistance and ring-crush
strength of kraft paper and corrugated paper.Completely replace the usage of
internal sizing agent. Application temperature should be bel
