I have been experimenting with bottled cold Franklin hide glue. I am interested in using it to attach trim and molding. I like hot hide glue because of ease in clean up but there is very little open time before it gels. I was pleasantly surprised at the strength of a joint made with cold hide glue. After an overnight clamp, the joint was stronger than the mahogany. Attempts to seperate the joint resulted in wood fracture with maintenance of the joint glue line.
My question is "what is the longevity of a cold hide glue joint?" As a biologic product can I expext 20 year longevity? More maybe? Is there any scientific data on this?

Please refer to e-mail I sent you. Franklin was good enough to supply me with all the information you might require including an attachment which outlines a study conducted by Stanford U. Luckily this study compares cold liquid hide with hot glue. I hope you find this valuable.

Howard, I have a quantity of “Coxes cold glue”, I acquired in the late 60's, this is excellent glue that has given over 40 years of reliable service to myself, and other users in the UK? It stands equal on strength and durability, to any hot glue, sold today.

I sent it to John Walkowiak with the impression he would post it. I have no idea how to get a pdf onto a post. You can tell me and I'll post it or you can email me and I will forward everything to you.
 
For a PDF file select the 'text' button, highlight all the text using the mouse, select 'copy' and then paste into your message on this forum.  Or click 'edit', then 'select all', then 'copy' and then paste the result.  Despends which version of Adobe you have.

My email won't send anything to your email address. Get some body else up to the plat and I'll e-mail it to them.
 
Sorry Fran, I didn't know you were expecting me to post the article. The link you posted works and is better than copying 10 pages here. The reply you received pretty much sums it up. Thanks again for sharing the information. The liquid Titebond hide glue is great stuff and I am glad they are still making it. If one doesn't need or want the quick tack that the hot glue provides it works very well. It is not the glue to use for your outdoor furniture in Florida, however!

Subject: RE: liquid hide glue


We've found that the environmental conditions that the bond is exposed
to is very important. The Hide Glue is affected by both heat and
moisture. Under ideal conditions the life span of the bond is
indefinite. When exposed to heat and or moisture the bond will be lost
rapidly, within a day in most cases. I've attached a study done at
Stanford University that will address some of these questions. They
compared the Titebond Liquid Hide Glue with hot pot hide glue. The
conclusion was that the Titebond Liquid Hide Glue was as strong or
stronger than the hot pot hide glue in normal conditions. When heat and
moisture is added, the Titebond Liquid Hide glue loses two-thirds of its
strength, while the pot hot hide glue loses one-third of its strength.�
