Polycup™ Crosslinking Resins

<p>Polycup&nbsp;crosslinking resins are formaldehyde-free, water-based resins that are reactive with amine, carboxyl, hydroxyl and thiol functionality. They promote water resistance in polymer systems that are typically water-soluble or water-sensitive. Polycup resins are commonly used to produce filtration media, cellulose meat casings, adhesives, inks and top-coatings.</p> <p>The&nbsp;environmentally friendly resins also impart toughness to formulations and improve adhesion to low surface energy substrates. They&rsquo;re a safe and environmentally responsible alternative to traditional crosslinking resins; Polycup resins contain no formaldehyde, VOCs, APEs/NPEs or SARA 313 components.&nbsp;</p> <p>Polycup resins provide benefits such as:</p> <ul> <li>Improved adhesion</li> <li>Improved durability and strength</li> <li>Enhanced flexibility</li> <li>Greater water resistance&nbsp;</li> </ul> <h2>Application Considerations</h2> <p>Polycup&nbsp;resins are available for industrial, indirect food contact and direct food contact applications. When you plan to use polymer resins, keep these considerations in mind:</p> <ul> <li>Polycup&nbsp;resins typically require temperatures from 80˚C to 150˚C for effective crosslinking; at lower temperatures, the resin requires longer time to set.&nbsp;</li> <li>Resins work over a broad pH range, with optimum performance between pH 7 and pH 9.</li> <li>You&nbsp;can extend the shelf life of formulas containing a Polycup resin by lowering the pH, temperature or Polycup resin concentration.</li> <li>Typical dosage rates (dry basis) are 0.25 to 5 percent.</li> <li>Add&nbsp;resin to well-agitated aqueous systems; to improve blending, pre-dilute with water using an in-line static mixer.</li> </ul> <h2>More Information</h2> <p>To learn more about Polycup crosslinking resins, or if you would like free technical advice on your specific application,&nbsp;<a href="/en/contact/ask-expert/">ask a Solenis expert today</a>.</p>
