Benefits of LED Cured Adhesives in Medical Applications

Selecting an adhesive is often a difficult task because it involves give and take between the end-use and manufacturing requirements. When it comes to bonding applications in the medical industry, the challenge is even greater because of strict specifications and safety constraints. A common standard for adhesives in medical devices is biocompatibility. In North America, the most widely accepted test for biocompatibility is United States Pharm acopeia (USP) Class VI. In tended to evaluate the suitability of polymeric materials for direct and indirect patient contact, the USP Class VI regimen consists of a series of in vivo reactivity and toxicity tests. These tests involve injecting and implanting samples of the material under consideration into mice and rabbits, which are then evaluated at fixed time intervals for any ill effects. ISO 10993 is another standard that tests cytotoxicity and is used to determine an adhesive’s compatibility with blood and body fluids according to the requirements of the Elution Test, ISO 10993-5 guidelines.
