A Medical Device with Adhesives Bonding Plastic and Metal

Adhesive Solutions for the Medical Industry

If you're in the market for an adhesive solution for your medical application, H.B. Fuller's got you covered. Whether you require a UV curable product, an instant adhesive, an epoxy, or a hot melt, our full line of medical adhesives are the premier choice.

Our products have the consistent quality you can depend on to conform to all of your company's production standards. Our manufacturing processes are ISO 13485 certified to ensure that your medical adhesive is consistently made the same way–every time. We are among only a few medical grade adhesive manufacturers in the world to be certified to this standard.
Biocompatibility also is an important factor. Many of our products biocompatible adhesives and have passed ISO 10993 for cytotoxicity, irritation, and sensitization so you can develop new medical devices with confidence.
We ensure that we do our part to exceed your expectations so you can focus on the end product. Whether you require a medical grade adhesive that is elastic, low viscosity, medium viscosity, high viscosity, flexible, has a quick set time, or anything else, you can entrust H. B. Fuller with your medical bonding needs.

Adhesives for the Medical Device Industry

Medical adhesives applications vary widely, but typically involve the bonding of plastics and metals. Though bond strength requirements are typically within reach for many medical adhesives from H.B. Fuller’s standard line, medical devices present a variety of unique challenges beyond strength. In addition to bonding parts together successfully, medical adhesives must also be compatible with direct or indirect contact with the body (depending on the application), and may be required to withstand sterilization through a variety of potential methods. Furthermore, certain substrates may necessitate the use of primers or other surface preparations in order to achieve satisfactory adhesion.

Medical Device Substrates to Be Bonded

When selecting an medical adhesive solution, the most important factor to consider is the specific composition of the materials being bonded. Broadly speaking, surface energy is the primary determinant of a substrate’s affinity for bonding—the higher the surface energy, the easier it is to bond the substrate. Recently, as a result of the growing concern over the health effects of phthalate-based plasticizers (e.g. DEHP) and the Bisphenol A monomer, PVC and polycarbonates have seen diminished use as substrates in medical device design.
From a medical adhesive standpoint, the widespread replacement of these easy-to-bond, high surface energy plastics with low surface energy alternatives like Pebax® has made bonding medical devices much more challenging. It is therefore imperative to know exactly which substrates are being bonded, and to work with a medical grade adhesive supplier comfortable working with the difficult-to-bond substrates increasingly common in medical device design, like H.B. Fuller.
