« Part 10: Inlay onlay with the Inlay Kit Part 11 of Tool Tip series Part 12: Liquid Hide Glue expired no good Pt 2 Stress test results »

Earlier in 2014 I was working with Liquid hide glue, and had a container on the shelf, upon checking it there was a shelf life expiry date 20/2010 so I went and bought another.

I did some tests on both at the time, pre May 2014 and I did not see any discernable differences in the expired glue and the fresh batch I had just bought, so both went on the shelf.

There they stayed until today, I was readings Stefangs blog on his home made LHG.

He conducted some strength destruction tests on his batch of glue, and noted LHG had a short shelf life.

So this prompted me to get my lot out again.

Upon checking I found the batch I bought earlier this year had now also expired in May 2014.

I was going to do some more tests to see if there was any difference in the expired batch and current batch but this was not to be the case.

As I was not keen to spend another $14 AUD just to do the tests I decided to use both expired batches, so here we with Part 1 the Glue up and technical information of the products.

Firstly here is a shot of both samples.

and the small print on the back showing the expiry dates.

Bottle B

Bottle A

First up a viscosity or settling test, as this will indicate a problem if there is a vast difference in viscosity.

Glue up Tests

Test 1

I applied a sample of glue

Initally joined together and then separated to check glue spread.

Test 2

I again applied a sample of glue

Then did a glue spread check again.

Test 3

A result of reading the glue should be applied with a heavy spread.

Checking the glue spread again.

Apply clamps for 30 minutes

After 30 minutes had expired I removed the clamps and took another shot of the
settling sample.

The skin of the glue must have set in the 30 m as there was an ant walking around on the glue, maybe he was a small LJ.

I will now leave them for 24 hours and continue with Test No2 the stress test in 24 hours

Some Preliminary observations/results

It appears the 20/2010 sample B is less viscous (more runny) then the May 2014 Sample A.
This is most evident in the settling sample and in the meniscus of the test samples.

This is interesting Robert. I do like the idea that my homemade LHG will not go out of date and I think the longer clamping time is a price worth paying. I would of course think differently if I were using LHG on a frequent basis, but as an infrequent user I would find it very inconvenient to reach for a product and find that it is outdated. Looking forward to seeing the final result of your tests.

Mike,

I checked out when I bought the LHG, it looks to be Nov 2013 when I was working on the Curved Front Box project that I was posting as progress blogs.

So knowing that date it appears the the shelf life for LHG is only about 6 months.

I will have to get onto the titebond site and check, but regardless it a pretty poor shelf life.

Amazing how time goes by I didnt think it was so long ago, I had better get it out and do some more work on it.

-- Regards Robert

I just checked Titebonds web site the spec sheet for LHG specifies 12 months as long as the cap is on tight.

So knowing that and the fact I purchased it in Nov 2013 it should still be in date shelf life wise.

So its anybodys guess how long it had been sitting on the shelf possibly since May 2013 six months before I purchased it.

Buyer beware !
