Moisture Resistant SAE Surface Sizing Agent

Product Specification

Feature

Customized anti-moisture reversion molecular structure forms dense closed protective film on paper surface, blocks continuous infiltration of ambient moisture, prevents paper strength decline, softening and box collapse caused by moisture backflow in rainy seasons, cold storage and long-distance maritime transportation. Distinct from general-purpose surface sizing agent, it maintains stable hydrophobic performance after long-term placement in humid environment, avoids gradual failure of water-proof effect of ordinary sizing products with time going by. Can fully replace internal sizing agent for production, no curing period required, finished paper obtains instant and durable anti-moisture performance after drying, shortens production cycle. Good compatibility with common industrial starch, directly mix with starch liquid for surface sizing, effectively lower overall chemical consumption cost without modifying original workshop feeding process. Remarkably retain paper ring crush strength and surface rigidity under high humidity condition, avoid sharp drop of physical indexes of packaging paper during damp storage and transportation. Superior emulsion stability, long storage validity period at normal temperature, no delamination or deterioration during storage and pipeline circulation, stable batch-to-batch performance. Low foaming characteristic adapts to high-speed surface sizing machine operation, eliminates bubble pinhole defects on paper surface, ensures smooth running of sizing circulation system. Wide adaptability for virgin wood pulp, chemical pulp, mechanical pulp and compound recycled pulp, consistent anti-moisture effect under fluctuating water quality and temperature working conditions. Reduce viscous dirt accumulation on sizing roller and drying cylinder, decrease downtime cleaning frequency, extend service life of paper machine fittings. Lower overall reject rate of finished paper in post-processing such as printing, creasing and die-cutting, bring stable yield benefit for packaging paper manufacturers.
