1) Ws-1D wet strength agent for papermaking is water-soluble, cationic and thermosetting resin with high cationic density, strong fixation on fiber and obvious improvement of wet strength effect.
2) It has the advantages of high efficiency, suitable for neutral papermaking, easy recovery of damaged paper or waste paper, non-toxic and so on. The organic chlorine content is low and can be used in food, medicine and other packaging paper.
3) suitable for all kinds of wet strength paper. The product can be used as a wet strength agent, but also as a retention agent for emulsion rosin and reinforced rosin glue, a synergist of neutral sizing agent and cationic starch modifier.

3.Usage of WS-1D
1) When in use, dilute it with water for 10 times and then add it to the slurry tank or directly inject it into the slurry delivery pipe with a metering pump.
4. Packaging and storage
1) Packed in 50kg to one ton drums
2) It is suggested that the optimal storage temperature should be higher than 4.4 ℃ and lower than 32 ℃. If the product is frozen at low temperature, it can be melted and used immediately after mixing evenly.
