Shelf life section[edit]

This section seems to be fairly minor, since it doesn't offer very specific information (ie. "Some glues have a limited shelf life" doesn't tell us much). Maybe this needs to be incorporated into the particular examples as sorted by reactiveness? — SelectivelyPermeableStudent (talk) 18:02, 10 April 2021 (UTC)[reply]

Science of the bonding properties[edit]

I was looking for an explaination/understanding of the science of how the glue adheres to the surfaces being glued, ie is it surface tension, chemical bonding, electostatic forces or what. This could be good information for understanding why different adhesives work with different materials and why they may fail. I know nothing on the subject so really needs some expert/chemist with some time to write something. Thanks —Preceding unsigned comment added by 203.51.39.214 (talk) 01:20, 5 May 2011 (UTC)[reply]

Oreo example[edit]

What's with the Oreo example? That isn't international - Oreos are generally confined to the US of A. Mort42 (talk) 19:51, 26 January 2009 (UTC)[reply]

BP?!?[edit]

OK, so a bunch of new-world order types don't like AD/BC and instead insist on CE/BCE. Now, WTF is BP supposed to stand for in the way it is used in this article? First guess was "before people" but that doesn't really make any sense given that the article is about glue. Might have worked in an article about dinosaurs tho.

Can someone in charge just make up their f'n mind about what standard we are going to use, and then make sure we stick to it? I grudgingly accepted the idea that authors of articles about non-christian religions and cultures might want BCE/CE, but am lost as to what BP might mean here. "Before Petroleum"? Except that would be wrong, since tars have always been available on certain sandy beaches ... Zaphraud (talk) 22:41, 16 August 2009 (UTC)[reply]

Note .. if it is "before people", the idea that obviously intelligent non-homo sapiens should not also be considered "people" in terms of discussing the accomplishments of their civilization is at least as offensive to the ideals of equality as any religion-based date system ever was - at least AD/BC doesn't re-classify members of any civilization as animals. Zaphraud (talk) 22:45, 16 August 2009 (UTC)[reply]
It means "before present"; in other words it's synonymous with "ago". Ewulp (talk) 23:36, 16 August 2009 (UTC)[reply]
According to https://en.wikipedia.org/wiki/Before_Present, BP means "before 1950". 94.30.84.71 (talk) 20:49, 13 September 2022 (UTC)[reply]

Plastic Wrap[edit]

"Plastic wrap displays temporary adhesive properties as well." Really? So does jelly but that doesn't make it an adhesive. Shouldn't this be removed? Shepherdtech (talk) 23:07, 1 April 2010 (UTC)[reply]

Thanks for the heads up. I've removed it. Wizard191 (talk) 23:34, 1 April 2010 (UTC)[reply]

Polyvinyl acetate[edit]

Isnt polyvinyl acetate a thermoplastic? It appears as thermosetting in the article? Sturgman (talk) 18:10, 16 June 2010 (UTC)[reply]

Yup, I fixed it. Thanks! Wizard191 (talk) 23:20, 16 June 2010 (UTC)[reply]

Birdlime[edit]

How well does traditional birdlime stand up against adhesives on the modern market? (I ask because I can't picture capturing birds on the branch using any of the usual stuff) Wnt (talk) 21:34, 26 August 2010 (UTC)[reply]

History[edit]

The history section presents a somewhat misleading picture.

  • The way the section is structured, it implies that animal glues were strictly prehistoric; in reality, animal-skin-derived glues were in widespread use throughout the pre-modern period until the more convenient bottled stuff replaced them in all but the most specialized applications. (Reproduction furniture makers, for example, still use rabbit skin glue.)
  • Egg whites (glair) were commonly used as a binder for paints, but make a less satisfactory gold size than a proper gesso, made with some sort of animal glue plus a 'body' agent such as slaked plaster. Other gold sizes (which give a more flat/matte effect then the mirror-finish of gesso) include garlic juice or gum ammoniac.
  • I believe at least one of the medieval artists instruction manuals mentions milk glue, well before the 19th century.

Animal glue[edit]

At least in the mid-20th century, and perhaps even at present, hot animal glue was preferred by luthiers for joining the top plate (front) (and, probably, the back) of a violin (and other similar stringed instruments) to the ribs (sides). It can be cracked apart for repairs with minimal or no damage to the wood. As well, it was the adhesive/sealant of choice for pipe-organ building and repairs, at least by some workers in that field. I can remember as a child in the 1940s watching my parents heat up brown translucent flakes of animal glue in a hot pot (water-jacketed)? It was applied hot, and perhaps bonded well as soon as it was cool; I'm not sure. It had a distinctive odor.

It would not be surprising to find that animal and fish glues are still used by some makers of folk instruments worldwide. Nikevich (talk) 14:59, 5 January 2012 (UTC)[reply]

Sex and glue[edit]

The first line of the second paragraph begins "Adhesives are used for adventurous sex positions, gluing you genitals to a wall ;)". No citation is given and wink makes me suspicious. Orangutanlibrarian (talk) 10:42, 25 November 2011 (UTC)Orangutanlibrarian[reply]

Fixed. Grantmidnight (talk) 16:23, 25 November 2011 (UTC)[reply]

"Glue" vs. "Adhesive"[edit]

I was rather disappointed, although I'm not an expert, by what seems to be lack of rigor in the use of these terms in what, on the whole, strikes me as an excellent article. While I'm no professional in the field, I have been quite interested in adhesives for just about all my life (I'm almost 76).

There's no denying that common usage (in English) prefers the term "glue"; it's monosyllabic, and universally understood. "Adhesive", imho, can run the risk of seeming pedantic. Several decades ago, I read that the term "Adhesive" is generic, and "glue", strictly speaking, is one type of adhesive (probably defined as primarily earlier technology, and probably/typically composed of animal/fish-derived substances). Until I read this article, I have kept that distinction*. It seems that the usage of "adhesive" and "glue" in the article is somewhat inconsistent, but considering that my belief is that of an amateur, I haven't changed any text. Nevertheless, I hope to see a clarification in the lead sentence [s] of the article regarding common usage and (versus?) the exact definition of "glue".

  • Much as I still maintain that soap is no longer in common use, and plain soap is hard to find; "soap", these days, implies detergent, but, technically, differs chemically. Soap was notorious for forming insoluble curds when used with hard water. Nevertheless, I'll accept "soap" as common usage to mean "detergent". Brevity is often a virtue.

Applications[edit]

This article (and it is not alone) fails in one of the primary purposes of an encyclopaedic article. A layperson seeking information about adhesives is likely to want help in finding the best choice for a particular task. A section devoted to this would be best, although a poor second would be relevant information under each glue type section. treesmill (talk) 10:10, 5 May 2012 (UTC)[reply]

Recent Edit to Preview and History Section[edit]

I have recently replaced the preview and history sections with what I consider better written, verifiable ones. Please review and post recommendations. HIST406-13rgrover1 (talk) 19:46, 17 April 2013 (UTC)[reply]

overly general?[edit]

I feel like this should be a category instead of an article. Attempting to lump all types of adhesives into one article invite excessive simplifications and results in a poor description of any given topic. You wouldn't try and describe every type of vehicle in one single article, because you wouldn't be able to provide an appropriate level of information on any particular vehicle. This is especially apparent in this article, as many of these different types of adhesives have bonding mechanisms with no relation to any other adhesive in the article. It's like trying to explain helicopters and boats in the same article. — Preceding unsigned comment added by 66.42.152.225 (talk) 22:48, 17 June 2013 (UTC)[reply]

This is a survey article to give an overview of the topic, with pointers to more-detailed information in other articles. It is also used to provide comparisons of different adhesives, which cannot be done by a simple category. This article does need improvement in many areas, but the overall format is appropriate.

One-part vs. 2-part adhesives[edit]

The section on one-part adhesives has a subsection describing a two-part adhesive that cures when exposed to heat... Doesn't that make it a 2-part adhesive and therefore shouldn't it be in that section? Or am I missing something here? KDS4444Talk 14:42, 15 December 2013 (UTC)[reply]

'broken' reference[edit]

I don't know how references are supposed to work, but the link at

  Mittal and Pizzi 2003, p. 3.

is not helpful. On careful examination, it is, itself, a reference to the bibliography section, but it doesn't work: clicking on it does not take you to the bibliography section. — Preceding unsigned comment added by 124.188.143.67 (talk) 01:34, 11 October 2020 (UTC)[reply]

Working temperature ranges[edit]

I have been asked to re-fix a handle which is no longer spot-welded to a bowl (17cm across, 6cm deep, about 0.5mm thick; handle is bent rod, 5mm diameter; both are stainless steel) which is apparently used for boiling but might be put in a refrigerator.

So I need a glue which has a working temperature range encompassing say -20C to 110C. Most glue manufacturers do not, as far as I can see, give that sort of information (but I knew of one type which claims an upper limit of 1300C).

I suggest, therefore, for the Article, a table of properties, giving for each generic type of glue: whether it sets hard or flexible, its setting time at normal temperature, its working temperature range, etc. For some jobs, that table could be enough to show what is needed; for others it could at least eliminate some categories.

I don't know enough to begin writing such a table. 94.30.84.71 (talk) 22:07, 13 September 2022 (UTC)[reply]

"Chemical weld" glues[edit]

Perhaps I missed it, but I don't see mention of adhesives that work by partially dissolving the items to be joined so that they fuse then reharden as the solvent(s) evaporate. Examples include plastic model cement, which softens and fuses polystyrene, and the cement used with PVC pipe and fittings. (There is even an enzyme used in modernist cooking that bonds meats this way.) This would be a sub-classification of the drying type glues, but the method of bonding is sufficiently different from others as to warrant its own description.

I know a little about this, but am not sufficiently expert to write such a section well. Someone more knowledgeable that I should, please, add this. Joe Avins (talk) 13:17, 23 September 2022 (UTC)[reply]
