Adhesives
DuPont Global Specialty Solutions (GSS) METHOCEL™ cellulose ethers and POLYOX™ water-soluble resins offer outstanding adhesive functionality. For a typical application, such as paper converting, our products can be used to deliver the desired result. In other applications, METHOCEL™ and POLYOX™ polymers enhance the functionality of other adhesives. These polymers can also be used as a thickening agent for other adhesive compounds to reach the required viscosity.
GSS supports its customers around the globe to develop, optimize, and manufacture adhesive solutions.
Key Adhesive Applications
A typical application of our METHOCEL™ and POLYOX™ polymers is paper converting. Those are usually first-choice polymers when formulating paper adhesives, especially towel and tissue adhesives (fugitive glues). Our product range, which includes other cellulose ethers, provides:
- Numerous polymer options to adapt adhesives to production equipment and finished product requirements
- Customizable viscosity and wet tack allowing for faster machine speeds
- Robust, proven-to-perform formulations, with improved consumer acceptance
- BfR / FDA food contact compliance
- Global footprint
