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
absorbency.
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.
Advantage
Features
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.
