Transposable adhesives: Acrylic Pressure-Sensitive Adhesives with Reactive Components

摘要

Pressure-sensitive adhesives (PSAs) have been an integral part of many industries that require the bonding of two or more materials. PSAs are commercially available in many forms: hot/warm melts, solvent borne, water based and syrups. They are used for applications as simple as paper labels to high-performance tapes used to bond two pieces of an automobile. Regardless of the application, PSAs have a set of viscoelastic properties that exhibit permanent adhesion characteristics once applied to a substrate. These adhesion characteristics are constant outside the typical responses from degradation from external environmental conditions, such as temperature and chemical exposure.
