Adhesives and Epoxies Q&A
-
I have an application in which opaque parts bond with a Super Glue-type cyanoacrylate. There is much surface area and I have a very good bond. Will gamma sterilization affect my bond strength?Answered January 28th, 2010 by Expert:Most cyanoacrylates will survive 1×, 2×, and sometimes even 3× gamma sterilization without a significant impact on bond strength. However, repeated gamma sterilization will add additional cross-linking, which will start to reduce elongation. As most cyanoacrylates are already brittle materials (depending on the grade), the adhesive may become even more brittle. Drop tests, impact testing, or tensile testing may be a good indicator of the final impact on your bond strength.
