Yes, funny stuff but what exactly is Titebond? I like the stuff and use it exclusively but have never been able to figure out what the stuff actually is. A witches brew? Here is what Titebond says in its specification which is basically meaningless:
AAMA 808.3
AAMA 808.3 provides specifications and test methods for exterior perimeter sealing compounds for use with fenestration products. Products meeting the requirements of AAMA 808.3 pass testing for cracking, bond loss, staining, hardness, >90% cohesive failure, slump, stain migration, low temperature flexibility and water resistance.
Well thank you very much Mr. Bond. Further investigation leads to this:
Aliphatic resin emulsion (ARE), commonly referred to as "yellow glue" or "carpenter's glue", has a similar use profile and relative ultimate strength as PVA. The two glues differ in grip characteristics before initial set, with PVAs exhibiting more slip during assembly and yellow glue having more initial grip. Brands include Titebond and Lepage.
