Adhesive nasal strips were first created in the early 20th century not for people but for racing horses. Horse trainers found that their horses raced better with the strips in place.
Converting webs of pressure-sensitive adhesives (PSAs) presents a variety of challenges. The inherent sticky properties of adhesives can be problematic throughout the slitting and rewinding process.
Over the last 50 years, the aerospace and aircraft industries have used silicone in an ever-growing number of applications. Silicone inherently has high dielectric strength (typically ≥ 500 V/mil) and a large coefficient of thermal expansion (CTE), allowing it to absorb stresses during thermal cycling.
Although five major bonding mechanisms are associated with adhesion promotion, two primary factors predominately influence the adhesion of any type of polymer to another substrate: chemical surface-to-surface interaction at the molecular level, and the wettability of the adhesive so as to enable surface spreading. Adhesion values can also be influenced by the matrix, or vehicle, that enables surface wet-out.
Adhesive bonding can be used to assemble identical materials or materials of different types; the purpose of such an assembly is to transfer mechanical loads in a given environment.
Industries ranging from automotive and consumer electronics to building and construction are designing and manufacturing products that call for increasingly sophisticated bonding solutions.
A new coating could help medical implants function better.

Tiny implants to monitor bodily functions or to provide insulin or other drugs based on immediate need would be an advancement in personalized medicine. But a problem inherent in implants is the tendency of the human immune system to recognize the device as an invader and encapsulate it, preventing the device from doing its job.
Roof tile adhesives can provide strong adhesion, including resistance to hurricane-force winds.
