Wet Strength Agent


Wet Strength Agent



        are water-soluble polymer products. The most
commonly used solutions are formulated with polyamide-

epichlorohydrin (PAE) resin chemistry and are intended 

primarily for the consumer market. PAE resins function 

in neutral/alkaline papermaking processes. They have a 

high level of Wet strength agent permanence, help improve 

machine efficiency and do not adversely affect paper 



        Wet strength agent work during the curing process, 

when the functional groups on the polymer react with cellulose 

fiber to form a covalent bond. The polymer molecules cross-link, 

forming a network in the cellulose web that provides strength 

when the paper becomes wet. 



 – Paper production efficiency: After using the product, the paper production efficiency will be improved.
 – Wet strength effect: Easy to absorb water, with obvious anti-scratches effect.
 – With excellent performance of keeping luster and color, do not reduce the whiteness of original fiber.
 – With stable chemical properties and good compatibility.


       The product has good characteristic to reduce the problem of dropping off powder which 

is can widely used in the tissue, package paper, culture paper and other kinds of  wet strength 

of paper production.
