Dear Ted,Everyone has their glue preference and I respect their choices. Hide glue is a good glue andas you say its been used for a long time. If I was to make an argument for changing to a resin glue it would be this. Hide glue is sensitive to both moisture and heat which can loosenthe glue bond. A urea resin is a catalytic glue which it not affected by these two conditions.I think a lot of older furniture that has the veneer coming off has been pressed with hide glue.That is not to say hide glue does not bond well, just that its hard to keep veneered pieces from being affected by moisture and temperature over the long run. I think the main reasonto use hide glue is on antique furniture where the original condition is being maintained or whenyou want to be able to remove the veneer later on. Hide glue is always reversable. This does say something about the glue though.These are my thoughtsSincerelyDarryl Keil : Hi:: I made a small study box a few years ago using 0.5" MDF (Zebrawood face/Maple to balance). I glued the veneer to the MDF : using Franklin's liquid hide glue (room temp. solubility due to dissolved urea, I believe...) and found the procedure extremely : easy (cold clamp). The glue went on easily with a short nap roller and I saw minimal bleed-through, although enough to : convince me I was getting good coverage. : My question is this. Why would I do it any other way? My box is only a few years old, (and it's small) but it shows no sign of : peeling or bubbling. I understand the theoretical benefits of a hard glue line (via a urea resin like Unibond), but I believe that : needs to be counterbalanced by two things: 1. Wood (even MDF) moves, and presumably this movement is continually : degrading the veneer/substrate interface... and 2. Hide glue has a long history of working very effectively (Egyptian : sarcophogi!) - I'm sure even the oldest examples of veneer bound with urea are no more than 30 to 40 years old.: Now admittedly, liquid hide glue is not the same as traditional hide glue, so it's not a fair comparison. But what I'm looking for : is someone knowledgable enough to convince me that I need to move to urea resin... I do plan on tackling more involved : projects (larger panels, curved work, etc...) and I want to know the limitations of the 'technology' I'm currently relying on. : Any advice will be greatly appreciated.: By the way, this is a wonderful forum,: -t
