Table 2: Results of Group 2 Testing
Table 2 provides the results of Group 2 testing. No significant differences were observed in Group 2 epoxy FTIR spectra. Calcium carbonate was observed by PLM in all Group 2 epoxies but did not yield discriminating data. Barium sulfate was identified by XRD in J-B WELD and J-B KWIK epoxies, but not in Metal/Concrete Epoxy. Barium was identified by XRF in J-B WELD and J-B KWIK epoxies, but not in Metal/Concrete Epoxy. J-B KWIK exhibited a distinguishable pyrogram from both J-B WELD and Metal/Concrete Epoxy.
