| Résumé : |
Pressure sensitive adhesives (PSAs) are found everywhere in our society. Solventborne PSA formulations traditionally were based on modified rubber chemistry. Today they are being replaced by low-VOC, fast-curing systems such as UV-cured PSAs.
This article describes current water-based and 100% solid UV-curable PSAs and their properties. Shear, peel strengh and tack properties are reported for systems with various oligomer and monomer contents.
The PSAs were prepared to minimize premature polymerization and evaluated by three test methods: rolling ball tack (RBT), 180° peel and shear. The article describes sample preparation, test methods and significant findings. These findings reveal a correlation between crosslink density and shear performance, tackifier content and peel strength, and system Tg. |
