PAE paper wet strength agent is polyamide epich resin, which is a water-soluble cationic thermosetting resin. It is an excellent wet-strength agent for paper making.PAE molecular chain contains groups with strong positive electric charge, which can strongly adsorb with negatively charged fibers or fillers. After heating, cross-linking and curing occur between the molecules, resulting in obvious wet strength properties of the paper. It is efficient, suitable for neutral papermaking, easy to recycle damaged paper or waste paper, non-toxic, and so on.PAE is suitable for making all kinds of paper with wet strength. Besides being used as a wet strength agent, it can also be used as a retention aid of emulsion rosin gum and strengthened rosin gum, a synergistic agent of neutral sizing agent, and a cationic starch modifier to improve the dimensional stability of paper.

3)The main Application:
This product is one kind of non-formaldehyde polymer nonpoisonous and odorless hydrogen ion index range is wide. Suitable for neutral copying paper under alkaline conditions a little it increases wet strong results and it is superior to urea aldehyde and resingather cyanoge amine and formaldehyde resin three times.
4) Functions and Usages
1. Obvious humidification effect:
Wet strength agent with the traditional urea formaldehyde or melamine formaldehyde resin, adding in the same dosage, the enhancement effect is obvious, according to the different pulp raw material and adding different doses can improve the wet strength commonly 80-100%, at the same time also can improve the dry strength, also due to the strong positive charge of molecular chain and the effect of fiber, but also can increase the pulp drainability and writing speed, improve the packing, plastic material and microfiber micro retention rate, the other in the feel of paper than urea formaldehyde or melamine formaldehyde resin such as soft, absorbent.
2. Wide PH range:
Since the wet strength agent itself is cationic, it can be absorbed by the fiber in a wide range of PH values from acidic to alkaline, achieving a good effect without the presence of aluminum sulfate. When the condition is neutral to slightly alkaline, the wet strength agent is more suitable for curing and has a better effect.
5) packaging and storage:
This product is packed with polyethylene plastic barrel a net weight of 200kg per barrel. This product should be avoided when stored under the freezing point and under high temperatures the most suitable temperature for storing is 5-22 degrees Centigrade this product is according to the above-mentioned conditions
