We have been using epoxy adhesives for many years in our assembly operations for metals and plastics. However, one of our suppliers is trying to convince us to try his polyurethanes. How do these adhesives compare to other engineering adhesives?
Pressure-sensitive adhesives (PSAs) are used in applications ranging from labeling food packaging to assembling electronic devices to mounting graphics displays. Although they have been around for decades and their use is widespread, manufacturers, converters, and printers may not understand the key differences between the adhesive choices available, how they’re constructed, or which are best suited for a particular job.
