Adhesives and Epoxies Q&A

Can oxygen inhibition be removed from cured parts without causing damage to the fully cured substrate area? We are looking to change our process to include a nitrogen blanket but have many components that cannot be completed due to the tackiness on the outer surface. We tried CRC Brakleen, but this cleaning agent affected the cured surface area as well as the tacky coating.Answered March 28th, 2011 by Expert:First of all, I would like to refer you to an earlier exchange in “Ask the Experts” regarding the inhibition of cure.
CRC Brakleen is a very strong cleaning agent that contains tetrachloroethylene and dichloromethane or ketone (depending on the packaging used). As you already noticed, these are chemicals that easily remove the tacky layer, but they also dissolve the cured adhesive. If oxygen inhibition cannot be avoided, the tacky layer should be removed using an isopropyl alcohol (IPA) wipe. IPA is less aggressive than CRC Brakleen and is commonly used for this purpose. We would always recommend a wipe rather than a soak.
