Time Should Play a Big Role in Picking the Right Adhesives for Medical Devices

When medical device manufacturers are choosing which adhesive to use in a particular device, what’s likely to be first and foremost in their minds is whether it complies with biocompatibility requirements, how well it bonds with the substrates, and whether it can meet all the other functional demands involved in the application. But they could be missing some important criteria in determining the best adhesive for the job at hand.

According to Intertronics, they could be overlooking the effects of the passage of time, in all its various forms. These range from the shelf-life of the adhesive, the time it takes to process it, its working lifespan, and how long it takes to cure.

One of the biggest threats lies in ignoring the expiry date on adhesives. Even if they have been stored unused in recommended conditions, in the original packaging, and negative effects aren’t immediately obvious, they can develop slowly over a period of time causing a decline in performance. Time constraints also apply to the working life and pot life of adhesives after they have been mixed or prepared for application.

Teamed together these can impact on the overall effectiveness of the adhesive and ultimately on the medical device itself. They can also lead to more material waste and reduced productivity, and push up the manufacturing costs considerably.
