Adhesive/Sealant for Attaching RFID Tags

"Hello, currently I am working with 2 Cal Poly professors to make monitoring operating room packs easier. Our goal is to be able to attach micro RFID tags to surgical tools so that they can be scanned and bookmarked. What type of adhesive would work best to attach these tags to surgical tools? The adhesive needs to be biocompatible and be able to undergo sterilization."

 

Assuming most surgical tools are stainless steel, and need to survive repeated autoclave, I would recommend looking at 2-part epoxies as your base chemistry. Options are available from Loctite, 3M, and Epoxy Technology, to name a few, and some have biocompatibility certificates on file. If the surgical tools are disposable or plastic, and only need to withstand a single autoclave cycle, EtO, or Gamma sterilization, then a light-curable acrylated urethane like the DYMAX 1120-M-UR light-curable medical device adhesive would be my first choice. Acrylated urethane light-curable adhesives have excellent adhesion, are simple to apply as a 1-part material, and cure in less than a second.
