Sterilization capabilities are an important consideration for the selection of polymeric adhesives, sealants and potting compounds for use in medical applications. Master Bond manufactures a number of adhesives, sealants, coatings, and potting and encapsulation compounds for use in the assembly of medical devices. These products retain their desirable performance upon exposure to various sterilization procedures. Many products withstand single as well as multiple sterilization cycles and are designed for both disposable and reusable medical devices.
Many of Master Bond’s sterilization-resistant adhesives are USP Class VI certified and are designed to adhere well to a wide range of substrates, including metals, glass, ceramics, and most plastics. These user-friendly products can be cured at ambient temperatures, elevated temperatures, or by exposure to UV light.
Adhesives, Sealants and Coatings with Outstanding Sterilization Resistance
Grades are available that resist the following sterilization methods:
- Steam autoclave
- Ethylene oxide (ETO)
- Gamma radiation
- Electron beam
- Hydrogen preoxide
- Cold chemical sterilants
The most widely employed sterilization methods for medical devices are autoclaving, radiation, ethylene oxide, plasma or corona discharge, and liquid sterilants. Epoxy polymers are among the most widely employed adhesives, sealants and potting compounds for repeated sterilization such as autoclaving and liquid sterilization. For disposable devices, the more common sterilization techniques are ETO, gamma radiation or liquid sterilization.
