Development of photoreactive UV-crosslinkable solvent-free acrylic pressure-sensitive adhesives coated at room temperature and used for removable and repositionable self-adhesive materials

Development of photoreactive UV-crosslinkable solvent-free acrylic pressure-sensitive adhesives coated at room temperature and used for removable and repositionable self-adhesive materials The goal of this article is to review the development of photoreactive UV-crosslinkable acrylic pressure-sensitive adhesives (PSAs) characterized by low viscosity, which can be coated at room temperature in the form of adhesive layers and are characterized by removable properties after UV-crosslinking. Surfactants and stearic acid have been used to improve the performance of the acrylic PSA, too. They are used for the manufacturing of removable and repositionable self-adhesive products, such as easy peel-able decorative films and wide range version of post-it articles.
