| Résumé : |
Pressure-sensitive adhesives (PSAs) have become more popular in demanding tape and label applications. Many high-performance PSA applications are dominated by solvent acrylic PSAs and radiation-curable PSAs because they can achieve much higher cohesive strength and heat resistance than other technologies, including typical emulsion PSAs. Due to these performance limitations, waterborne emulsion PSAs are used in less demanding applications.
Waterborne acrylic PSAs provide many advantages such as high solids, lower cost, low hazard, and environmental benefits. With these advantages, industry has been pushing the limits of emulsion technologies to close the performance gaps between emulsion and other high-performance technologies.
A new waterborne technology with excellent adhesion and high-temperature properties has been developed that can rival existing solvent acrylic and radiation-curable technologies that are currently used in high-performance applications. The high temperature resistance is measured by shear adhesion failure temperature (SAFT; PSTC-17 test method), which has been the biggest limitation of waterborne PSAs vs. radiation-curable and solvent acrylic PSAs. |
