Loctite shelf life

[Ian S CParticipant @iansc]

I work on the idea that if its still in the bottle, its OK, if the bottle is empty, it's reached its shelf life.

I don't know about loctite, but mature Stilton is inedible until at least a month after the date on the label!

Seriously though, I've noticed 'superglue' type adhesives go off quickly, presumably because of moisture getting in, whilst anaerobic adhesives seem to last.

It depends on how well the bottle is sealed . If atmospheric moisture is completely excluded product will last in useable form for many years . Any ingress of atmospheric moisture , however small , will cause rapid degredation .

Not quite the same question but a friend reminded me today of another degredation effect – accidental introduction of minute quantities of some common workshop substances will cause almost instant gelling of the whole contents of bottle .

Peter, I believe at lot of tablets and the like just become less efective to the point that they do nothing at all after the use by date, they apparently woun't do you any harm, but if you are unsure, it is best not to take them.

Regards Nick.

In general I agree with you, but I do not accept that tablets etc suddenly become unusable/ineffective the day after their "Do Not Use After" date. Maybe not even after a week, or a month, although I certainly wouldn't make a habit of it. But as happened recently, the old back pain flared up again, I went through the usual rigmarole of hot water bottle, then paracetamol, and finally Codeine Phosphate only to find that despite my regular checking, they were a week or two out of date. Now my Surgery tells us to allow 3 days before collecting repeat prescriptions so I used the old pills. Fortunately they worked. I now have a new set of pills.

The cream that I used was a few months out of date and that DID cause problems.

Regards,

Peter

Just as an aside, I've not had much luck with Loctite or equivalent adhesives. Or indeed many other adhesives. In fact, I find good old Araldite the best adhesive ever and I find it quite surprising just how often Araldite works after other adhesives have failed.

When I say Araldite, I suppose I should really say "2-part epoxy adhesives", but as I have only ever used Araldite as a liquid adhesive, and Milliput as a solid (?) adhesive, those are all I can recommend.

Dry pills are unlikely to degrade as the chemicals are 'locked' in place. Wet (water or oil based) preparations allow molecules to move and mix, so chemical reactions to take place.

There are exceptions. I'm sure.

Peter,

Assuming that by "Loctite" we mean specifically the Anaerobic Adhesives; I am intrigued …

I don't think that I have ever had a failure with Loctite [and I've used it in some fairly extreme situations]. It behaves rather like a cold version of soft-soldering .. Low peel-strength, but very effective in compression and shear.

Please let us know what problems you have had.

Michael,

To tell the truth, I haven't used them that much and can't really think when and where I did try them. I also think that on at least one occasion, it probably wasn't a suitable adhesive because I can remember thinking I'll try this and see what happens.

I have tried superglue occasionally. Again, that not really work.

I have a suspicion it may be down to a combination of surface preparation, specifically cleanliness and smoothness. Epoxy adhesives do have gap filling properties.

I know that on numerous occasions I have used good old Araldite because nothing else has seemed to work. Certainly on one item I have been, and still am, surprised that years later it is still holding – this was one of SWMBO's garden ornaments in the shape of duck where it broke across the neck. It is quite heavy and can still be lifted by the neck.

I have been using Araldite for nearly 50 years now, the first ocasion being a repair on my Austin A35 van. On these vehicles, the door windows were pushed/pulled up & down by a small piece of glass perhaps 10 x 50mm which was glued onto the window itself. When one came off, I used Araldite (what is now called the Standard version – 24 hours full setting time) to glue it back on. Initially, it was held in place with Sellotape or equivalent.

Araldite doesn't always work. Eg, little grandaughter presented me with a toy horse with a broken leg. I glued it up, but a few weeks later back it came. This time I pinned it as well.

As you can see, I like Araldite. I wonder if I'm addicted to it!!!

Regards,

Peter
