※Wet strength resin
Product introduction:
This product is a cationic polyamide polyamine epichlorohydrin polymer, able to quickly and efficiently adsorb pulp with negatively charged, thermosetting chemical reaction occur in drying section. And give paper wet strength, product is easy to be absorbed by the fiber, can be cured under neutral or alkaline conditions. This product can be widely used in decorative base paper, art paper, carte paper, food wrap paper, fruit-bay paper, medical paper, etc.
Specification:

Product features:
Enhancement affect is obvious, wet strength increase 5 to 10 times, dry strength increased 20% -30%. Positive charge density is high, it can increase the pulp drainability and papermaking speed, increase the retention rate of filler, glue and fine fiber. Do not contain “ free aldehyde”, at the same time avoid the paper yellowing after a long time. The range of application is wide. The fiber can absorb it from acid to alkaline broad PH range, can achieve good wet strength effect without adding aluminium sulfate.
It will achieve a better affect in neutral and weak alkaline conditions.
Dosage and methods: 　
1.0.5-1.0% to oven try stock, best use of PH value is 7.5-8.0.
2.Broken paper and waste paper recucling easy: Unbleached paper: the condition of beating can be controlled to the PH value to about 65c.
3. bleaching paper: adjust  PH value to 5-8, the temperature is about 5℃. The effect will be better if add a small amount of sodium hypochlorite.
