WebOct 15, 2024 · You can clearly see how to use FTIR to confirm adhesive bond failure modes. Figure 2 above shows this. “1” is the PET substrate, “2” is an ATR spectrum that shows PET and (acrylic) adhesive. I’m not going to talk about the adhesive in this post (my main interest). Spectrum #3 looks almost like “pure” adhesive, but it is not.
