Wood glue is very specifically used for wood. How does wood glue bond differently compared to other glues like epoxy or Elmer's glue? I'm not talking about what makes wood glue unique or special (water-based, non-toxic) but rather the specifics of it's bond to wood from a technical perspective.

Note: The wood glue I have in mind is Tight Bond wood glue.

  • I don't believe that answers my question (i even linked to it in my question). I'm inquiring about its bonding properties, such as making a chemical bond to the material vs other methods of adhesion.

    @Hooplehead24 I think it does answer your question (answer: it doesn't bond differently), unless you're asking how glue works in general compared to e.g. tape?

    Liquid glues tend to soak into wood, to some extent. Obviously that doesn't happen with nonporous materials; it also doesn't happen much with hot glue or tape gums (which is why those are removable). Outside of that...?

    This question is indeed not a duplicate since it asks a specific question that was not answered in its "duplicate". The question was neither asked nor did it evoke the answer that popped up in the US Forest Products Laboratory paper cited by @Hooplehead: The adhesive (PVA) sets when the water of the emulsion partially diffuses into the wood and the emulsified resin coagulates. There is no apparent chemical curing reaction, as with the thermosetting resins.
