Résumé : |
Many formulation factors can influence the performance of UV-curing pressure-sensitive adhesives (PSAs). Several basic material fundamentals should be considered, including polymer rheology, molecular weight, functionality and crosslink density. These topics will be addressed first to provide insight into the behavior of polymeric materials in PSA applications. The various raw materials in PSA applications. The various raw materials that are used in practical UV formulations will then be reviewed, as well as formulations for certain applications. Most commercially available UV-curing PSA systems are based on free-radical curing liquid systems, therefore emphasis will be on this technology. |
