I don't think super glue should be classed as a "drying adhesive", because when it cures it actually polymerizes in a chemical reaction. The chemical reaction is triggered by hydroxyl ions present in traces of water on the surface to be glued, so it might be classed as a reactive adhesive, but then again it might not, so I'm simply raising the issue here on the talk page instead of changing it myself.

My bad, already fixed -- I went and cross-checked. Thanks for the notification! The Anome 07:41 Oct 1, 2002 (UTC)

The article says that bonding is different from sticking, but does not say why. Can anyone out there explain? -- Heron 12:31, 14 Jun 2004 (UTC)

I would just like to say thank you for this article. It proved to be of great help to me, especially the way it states the categories of the glues in an organised way. Wikipedia is a wonderful place on the Internet.

Regarding the claim of quieter car engines due to "loctite" like glues, where's the source??? I thought engines were quieter in part due to better machining, tighter tolerances, etc, not that the parts were glued together. Maybe adhesives play some role but I don't think my old chevy 350 was noisy because of loose bolts. Could be wrong though, wouldn't be the 1st time. 08:56, 11 September 2007 (UTC)jawshoeaw

I second that, I do not know of any 'epoxy' in my engine (would it even resist the temperature?) (talk) 00:03, 1 November 2008 (UTC)


Who first invented glue? (school project)

Use the box at left to "search" for "glue" and you will be rewarded. FWIW, the word "first" in your question may be omitted without changing the meaning of your question. Sfahey 00:38, 3 November 2005 (UTC)

(I disagree that "first" is redundant when paired with "invented." Sir Isaac Newton and Gottfried Wilhelm Leibniz both invented Calculus, but the question remains as to who invented it first.)

touché. and in turn, "both" newton and leibniz suggests that they invented it together; "each" would do better.Sfahey 15:54, 8 March 2006 (UTC)

Soldering? Welding?

Is soldering or welding covered by "adhesive"? My gut feeling is that soldering is but welding is not in that soldering simply adds solder which "sticks" to the surfaces whereas welding melts the surfaces together to form a single piece. By that measure, though, solvent-based plastic cement isn't an adhesive since it welds. ―BenFrantzDale 07:28, 10 February 2006 (UTC)

How do they work?

To what degree do adhesives rely on the microstructure of the surfaces they adhere as opposed to relying on chemical bonding for their holding power? As a non-chemist, I wonder: If it is chemical bonding, what sorts of bonds can be so versatile to stick to nearly anything? ―BenFrantzDale 07:28, 10 February 2006 (UTC)

Good question. I've been under the impression that adhesion is basically suction, but at the microscopic level - is this true or false? --Starkruzr 06:28, 21 March 2006 (UTC)

The section on "reactive adhesives" covers much of this.Sfahey 19:34, 22 March 2006 (UTC)
Does it? It only says something about some reactive adhesives which use chemical bonding but doesn't explain how normal glues manage to stick...Although, I distinctly remember from a magazine somewhere quite a while ago that there's no unified 'glue-theory' (ie. uniformly accepted explanation as to why glues stick). - G3, 00:39, 25 April 2006 (UTC)

Adhesives work on the basis of molecular attraction. Materials with a high-molecular surface-energy attract each other; in order to bond a material with a low-surface energy (such as polyethylene), you need to engineer an LSE chemistry that will attract to the polyethylene. That is one, and a major element in engineering adhesion. You also have to factor in the the overall surface tension (see: Dynes) porosity and density of materials, as well as the kind of bond and stress (tensile, peel, cleavage, or shear) it may be introduced to in-application. TrulyTory (talk) 19:26, 22 April 2008 (UTC)


The failure section needs cleanup. It also should discuss toughness versus material strength versus bond strength. For example, super glue may be strong, but it is brittle so geometric considerations can cause it to fail by stress localization where a weaker but tougher adhesive would not fail. Similarly a hard adhesive bonding a soft material might fail at the interface because of stress localization at the edge of the interface. ―BenFrantzDale 00:39, 13 February 2006 (UTC)

YOU appear to be the one best able to clean it up.Sfahey 19:21, 15 February 2006 (UTC)
Thanks for the vote of confidence. We'll see. ―BenFrantzDale 00:04, 16 February 2006 (UTC)

remove the whole section cause i dont think any of it is both correct and coherent

I inserted a few things on adhesive failure types and testing methods ... .ferracin 18:30, 31 Jully 2006 (UTC)

The last line is really off base. It must come from an "adhesive" guy (or gal). A splitting failure of the adhesive may not be the goal. In some applications, such as tape or post it notes, you want the adhesive to be removed cleanly from the surface.

I agree, being in "adhesives" that last line is not necessarily true. The goal is to design failure where it best suits the application.

Duplicate with Glue ??

The Glue page seems to cover the same topic, and it looks to me like the two pages should be combined. —The preceding unsigned comment was added by (talkcontribs) .

Some entries may be merged into here, or perhaps the whole list, see also talk:glue. A simple merge/redirect won't do though, since glue is a disambiguation page and these two pages have slighty different purposes. Femto 14:35, 18 April 2006 (UTC)

Quiet automobile engines?

The sentence of how certain adhesives make car engines more quiet should either be motivated by a good reference, or removed. It seems far-fetched. Certainly, an old car with several loose bolts might rattle, but not all old cars had loose bolts, and they were still noisier than new cars. -- 06:40, 15 June 2006 (UTC)

Is that Locktite he's talking about? Its not used to contribute to vibration dampening in an engine, but to keep the screws from unscrewing themselves from the vibration. If a part is loose, then it will vibrate more, hence louder, and that is the only way using locktite would make it quieter.
Comment from FERRACIN : Like all polymers, the adhesive will have a filtering and damping effect on any vibration passing through the structure .... It is used by steel manufacturers in the automotive industry to limit vibration in complex steel structures. Beside that, I never heard of them in the engines themselves...
With all due respect, I suspect the original thought was that composites, which incorporate very advanced forms of adhesives, have been developed and are in current use in modern automobile engine manufacturing for a variety of purposes including reduction of: weight, cost, and noise. For example, we have GM's thermoset plastic Corvette valve covers, Chrysler's constrained-layer oil pans and multi-polymer valve covers, and ThyssenKrupp's steel-resin sandwich (ie, Bondal®) (used for engine covers and such). In addition, much work has been done to incorporate adhesives as a fastener replacement to eliminate squeeks and loose components in various parts of the automobile. A quick Google on "automotive adhesive" would probably yield enough hits to keep oneself busy for a while. ;-) JimScott 20:35, 1 May 2007 (UTC)


Have removed the insightful phrase "this is all poo POOPOOOPOOOOOOOOOPO" from Drying Adhesives paragraph.

Perhaps the author was thinking of Goop or it's predecssor, that old favorite, Shoe GOO; both widely popular and useful line of adhesives. JimScott 20:35, 1 May 2007 (UTC)

Bookbinding - why?

The section on "Polyurethane-based adhesives in the bookbinding industry" is interesting, but I don't think it should be on this page. Perhaps it should go on the bookbinding page, but it's a little too specific for this page. Any objections if it gets removed ? -- 20:41, 5 August 2007 (UTC)

5-year-old ceramic vessels?

In the section on "History" is written

Archaeologists have found 5-year-old ceramic vessels that had broken and been repaired using plant resin.

Surely this should be referring to vessels far older than five years old. --Dan Griscom 01:46, 21 October 2007 (UTC)

History section

The history section is awful. Badly needs reorganization. Care to have a crack at it? ike9898 (talk) 16:40, 22 November 2007 (UTC)

sounds like an ad

Near the end, it looks like different companies are trying to promote their products. Could someone with more expertise take a look at this?--07:01, 7 December 2007 (UTC)~

Henkel Corporation's page for the layperson

A good discussion for the layperson of different types of adhesive can be found at I mention this because I came across the page when I was looking for information on anaerobic adhesives. Henkel Corporation is a manufacturer of adhesives under several different brand names. --Eastmain (talk) 03:45, 2 May 2008 (UTC) Another reference website is, which is a non-commercial web portal dedicated to helping explain the fundamentals of adhesives and sealants.

Anaerobic Adhesives

Could someone add a section on anaerobic adhesives, or are they already in the article by a different name? --Eastmain (talk) 03:45, 2 May 2008 (UTC) Check out There is a summary of adhesive types listed there.
