In this paper, we introduce the basics of pressure-sensitive adhesives (types of adhesives, test methods for adhesive properties, and the mechanism of adhesion), and use rubber-based adhesives containing various additives as an example to explain the mechanism of durability (deterioration). Next, we explain that the research on changes in adhesive properties over time, focusing on the efforts of “time-dependent mechanism of adhesive properties and life prediction" conducted by the four industry-academia collaborative research groups of the Adhesive Research Group.
