<p>Kymene wet-strength additives comprise a family of products proven to significantly improve the wet strength of paper. Kymene additives have been trusted by papermakers for more than 50 years. And, thanks to our ambitious R&D program, they’ve only improved with time.</p>
<p>Commercial applications confirm that Kymene wet-strength additives provide a number of value-added benefits:</p>
<ul>
<li>Improved wet strength</li>
<li>Improved retention and drainage</li>
<li>Enhanced creping control</li>
<li>Improved dry strength</li>
<li>Reduced chemical costs</li>
<li>Improved machine runnability</li>
</ul>
<p>Today, Solenis offers the broadest portfolio of wet-strength resins in the world. We provide Kymene wet-strength additives in a wide range of solids content to ensure the perfect fit for your needs. Our portfolio can help you balance freight costs, shelf life and product stability concerns.</p>
<h2>How They Work</h2>
<p>Kymene wet-strength additives 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 permanence, help improve machine efficiency and do not adversely affect paper absorbency.</p>
<p>Kymene additives work during the curing process, when the functional groups on the Kymene 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. Kymene wet-strength products can also reinforce existing fiber-to-fiber bonds, which further enhance the strength of the paper.</p>
<p>For even greater paper performance, <a href="/en/research-and-development/innovations/hercobond-dry-strength-additives/" target="_blank" rel="noopener">Hercobond™ dry strength additives</a> can be used with Kymene wet-strength additives. This combination can increase wet and dry tensile performance by as much as 25 percent.</p>
