When someone mentions medical adhesives, the first thought that often comes to mind is skin adhesion. It’s understandable, since nearly everyone has worn some type of medical adhesive product—from a simple bandage to an electrode, athletic tape, IV cover, and so on. However, an entire world of medical adhesives goes unnoticed by many: diagnostics.
The characteristics of ultraviolet (UV)-cured acrylic adhesives outweigh alternatives when health, the environment, longevity, and durability are priorities.
Sealants and adhesives play an integral role in the building envelope. However, not all adhesive formulations are created in the same way or from the same materials. Some may actually interact negatively with various building materials or perform temperamentally in areas of the country that experience broader seasonal temperature fluctuations. Choosing the correct adhesive saves valuable time and reduces labor, as well as the likelihood of costly rework.

Panacol has developed a new UV-curable acrylic adhesive that is certified to USP Class VI biocompatibility standards for medical device assembly applications.
It is important to consider the variables associated with the LED source and proper measurement tools in order to understand, maintain, and control the adhesive curing process.
UV LEDs with peak spectral outputs of 365, 385, 395, or 405 nanometers (nm) are increasingly being used to cure adhesives formulated to work with LEDs. The impact of spectral differences should be evaluated based on the adhesive, photoinitiator package, and desired cure properties.
Beyond peak intensity and curing area, differences in uniformity can impact the delivered UV light dose and change the optimal setup for flood-curing systems.
When selecting a UV flood-curing system, it is relatively easy to compare the advertised curing area and the peak intensity of the different systems and assume that higher values mean higher light delivery.
