AB  - Glyoxal and glutaraldehyde are two viable alternatives to formaldehyde for the preparation of tanninresorcinol-aldehyde adhesive but lead to less resistant glue joint. Tannin-resorcinol-glyoxal (TRG1) and 
tannin-resorcinol-glutaraldehyde (TRG2) resins have been prepared and analyzed by matrix-assisted laser 
desorption/ionization time of fl ight (MALDI-ToF) spectrometry to understand the chemical process behind 
the pre-curing of these resins and possibly the causes of this lower resistance. The analysis showed that TRG 
resins are not a simple mix of resorcinol-aldehydes oligomers and fl avonoids, but a much more complex 
combination of various species including tannin-aldehydes and tannin-resorcinol oligomers.
