Cyanoacrylate reaction with water
WebSep 1, 2024 · Cyanoacrylates were initially deemed nonsensitizing because cyanoacrylate polymerization is quickly triggered by moisture on the bonded surface (e.g., metals, ceramic, glass, rubber, biologic tissue) and occurs within minutes (Sasseville, 2012 ). However, cyanoacrylates are now well documented sources of ACD ( Chou et al., 2024 ). WebOct 4, 2024 · As you can see from the reaction of cyanoacrylate from Wikipedia, the carbonyl ( C = O) groups do not react with the cyano acrylate which means that acetone should not react with your super glue. That does not mean though that any water present in the acetone won't. So you should make sure your acetone is dry.
