The underlying principle is known as \u201c<em>debonding on demand<\/em>\u201d. When heated, the complex polymer structures that are stable at room temperature break apart, allowing the adhesive bond to detach again. This is caused by predetermined breaking points in the molecule, whose number and required breaking temperature can be adapted to individual applications \u2013 even for temperatures well below 100 \u00b0C (212 \u00b0F). In this sense, reversible adhesives can be designed for defined thermal release profiles.<\/p>\n<p><center><a href=\"https:\/\/www.rct-online.de\/en\/adhesives-and-lubricants\/adhesives\/two-component-adhesives\/30377\/ptfe-adhesive-based-on-synthetic-rubber-contact-adhesive\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-5119 size-full\" title=\"PTFE Adhesive Based on Synthetic Rubber (Contact Adhesive) | For Bonding PTFE Parts with Other Materials\" src=\"https:\/\/www.rct-online.de\/magazin\/wp-content\/uploads\/2020\/07\/ptfe-kleber-auf-synthetischer-kautschukbasis-kontaktkleber.jpg\" alt=\"ptfe-adhesive-based-on-synthetic-rubber-contact-adhesive-reversible-adhesives\" width=\"300\" height=\"300\" srcset=\"https:\/\/www.rct-online.de\/magazin\/wp-content\/uploads\/2020\/07\/ptfe-kleber-auf-synthetischer-kautschukbasis-kontaktkleber.jpg 300w, https:\/\/www.rct-online.de\/magazin\/wp-content\/uploads\/2020\/07\/ptfe-kleber-auf-synthetischer-kautschukbasis-kontaktkleber-150x150.jpg 150w\" sizes=\"(max-width: 300px) 100vw, 300px\" \/><\/a> <a href=\"https:\/\/www.rct-online.de\/en\/adhesives-and-lubricants\/adhesives\/one-component-adhesives\/30370\/tangit-pvc-u-adhesive\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-5120 size-full\" title=\"Tangit\u00ae PVC-U Adhesive | Solvent-Based Special Adhesive for Tensile-Resistant Bonding\" src=\"https:\/\/www.rct-online.de\/magazin\/wp-content\/uploads\/2020\/07\/tangit-pvc-u-kleber.jpg\" alt=\"tangit-pvc-u-adhesive-reversible-adhesives\" width=\"300\" height=\"300\" srcset=\"https:\/\/www.rct-online.de\/magazin\/wp-content\/uploads\/2020\/07\/tangit-pvc-u-kleber.jpg 300w, https:\/\/www.rct-online.de\/magazin\/wp-content\/uploads\/2020\/07\/tangit-pvc-u-kleber-150x150.jpg 150w\" sizes=\"(max-width: 300px) 100vw, 300px\" \/><\/a><\/center><\/p>\n<p style=\"text-align: justify;\">If such reversible plastics were also used in the electronics industry in the future, the recycling of discarded electronic devices would become far more effective. Repairs to smartphones and tablets would also become more feasible with such reversible plastics, and some devices would not become scrap in the first place \u2013 batteries being a prime example \u2013 because components that are currently still firmly embedded in non-detachable potting compounds would become accessible and replaceable. Reversible adhesives therefore offer a potential route towards easier disassembly and improved repairability.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"A_Metal_as_an_Adhesive\"><\/span>A Metal as an Adhesive?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p style=\"text-align: justify;\">Compared with other joining and <a href=\"https:\/\/www.rct-online.de\/en\/fasteners\">fastening technologies<\/a>, adhesive bonding can be implemented with relatively little technical effort. It is therefore increasingly replacing conventional industrial joining methods such as riveting, screwing or welding, which also add weight. However, releasing adhesive bonds is usually not possible, as reversible adhesives are rarely used.<\/p>\n<figure id=\"attachment_5090\" aria-describedby=\"caption-attachment-5090\" style=\"width: 200px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-5090 size-full\" title=\"The French Chemist Paul \u00c9mile Lecoq de Boisbaudran (1838\u20131912)\" src=\"https:\/\/www.rct-online.de\/magazin\/wp-content\/uploads\/2020\/07\/Chemiker-Paul-Emile-Lecoq-de-Boisbaudran.jpg\" alt=\"Chemist Paul Emile Lecoq de Boisbaudran\" width=\"200\" height=\"230\" \/><figcaption id=\"caption-attachment-5090\" class=\"wp-caption-text\">The French chemist Paul \u00c9mile Lecoq de Boisbaudran (1838-1912)<\/figcaption><\/figure>\n<p style=\"text-align: justify;\">Gallium (Ga), a metal discovered in 1875 by the French chemist Paul \u00c9mile Lecoq de Boisbaudran (1838-1912), is non-toxic and chemically similar to aluminium. With a density of 5.9 g\/cm<sup>3<\/sup>, however, it is more than twice as heavy as aluminium. Gallium provides a simple way to solve the problem of separating joints and fastenings again with minimal effort.<\/p>\n<p style=\"text-align: justify;\">Its low melting point of around 30 \u00b0C (86 \u00b0F) makes this possible, and handling is straightforward. In its liquid state, at temperatures above 30 \u00b0C (86 \u00b0F), the metal is applied in a thin layer to the preheated surfaces to be bonded. These surfaces are then joined together, as in conventional adhesive bonding. Once cooled below the melting point, a firm bond is formed between the two material parts. The \u201cbonding\u201d process is also possible in humid conditions.<\/p>\n<p style=\"text-align: justify;\">If the temperature is raised above 30 \u00b0C (86 \u00b0F), the metal liquefies again and releases the bonded parts without leaving residues. Gallium can also be used successfully to secure screw connections by \u201clubricating\u201d the heated thread with liquefied metal, which solidifies after cooling and prevents the screw connection from loosening.<\/p>\n<figure id=\"attachment_5093\" aria-describedby=\"caption-attachment-5093\" style=\"width: 400px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-5093\" title=\"Liquid Gallium Beginning to Crystallise\" src=\"https:\/\/www.rct-online.de\/magazin\/wp-content\/uploads\/2020\/07\/gallium-fluessig.jpg\" alt=\"liquid-gallium\" width=\"400\" height=\"327\" srcset=\"https:\/\/www.rct-online.de\/magazin\/wp-content\/uploads\/2020\/07\/gallium-fluessig.jpg 600w, https:\/\/www.rct-online.de\/magazin\/wp-content\/uploads\/2020\/07\/gallium-fluessig-300x245.jpg 300w\" sizes=\"(max-width: 400px) 100vw, 400px\" \/><figcaption id=\"caption-attachment-5093\" class=\"wp-caption-text\">Liquid gallium beginning to crystallise<\/figcaption><\/figure>\n<p style=\"text-align: justify;\">Although gallium is a relatively rare and therefore expensive metal, and is particularly important in semiconductor production, it can be used successfully wherever especially gentle adhesion is required and the operating temperature of the bonded parts always remains below 30 \u00b0C (86 \u00b0F). One significant advantage of the metal is that the \u201cadhesive\u201d is reversible and can be recovered and used repeatedly. This makes gallium an unusual but technically relevant example within the broader field of reversible adhesives.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Of_Snails_Mussels_and_Geckos\"><\/span>Of Snails, Mussels and Geckos<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p style=\"text-align: justify;\">There are remarkable images of geckos remaining on smooth glass walls and even hanging upside down from ceilings for hours.

Because of its animal models, it is known as GECKEL, GECKO or MUSSEL adhesive.<\/p>\n<figure id=\"attachment_5099\" aria-describedby=\"caption-attachment-5099\" style=\"width: 400px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-5099\" title=\"A Type of &quot;Super Adhesive&quot; Prevents Blue Mussels from Being Washed Out to Sea in Strong Currents\" src=\"https:\/\/www.rct-online.de\/magazin\/wp-content\/uploads\/2020\/07\/miesmuscheln-kleber.jpg\" alt=\"mussel-adhesive\" width=\"400\" height=\"365\" srcset=\"https:\/\/www.rct-online.de\/magazin\/wp-content\/uploads\/2020\/07\/miesmuscheln-kleber.jpg 600w, https:\/\/www.rct-online.de\/magazin\/wp-content\/uploads\/2020\/07\/miesmuscheln-kleber-300x274.jpg 300w\" sizes=\"(max-width: 400px) 100vw, 400px\" \/><figcaption id=\"caption-attachment-5099\" class=\"wp-caption-text\">A type of \u201csuper adhesive\u201d prevents blue mussels from being washed out to sea in strong currents<\/figcaption><\/figure>\n<p style=\"text-align: justify;\">Rod-shaped structures in the nanometre range on the feet of geckos enable dry adhesion based on van der Waals forces. If these structures are formed from polymers based on mussel adhesive proteins, adhesion can be achieved on both dry and moist substrates. Such adhesives based on nanostructures are already used in biomedicine for wound closure and may in future also be used for bonding bone fractures. For medical and technical applications alike, reversible adhesives based on biological principles are attracting increasing attention.<\/p>\n<p><center><a href=\"https:\/\/www.rct-online.de\/en\/adhesives-and-lubricants\/adhesives\/two-component-adhesives\/31118\/high-tech-electrical-conductivity-adhesive-two-component\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-5124 size-full\" title=\"Electrically Conductive Adhesive - Two-Component | Heat-Curing Adhesive Based on Epoxy Resin\" src=\"https:\/\/www.rct-online.de\/magazin\/wp-content\/uploads\/2020\/07\/elektro-leitfaehigkeitskleber-zweikomponenten.jpg\" alt=\"electrically-conductive-two-component-adhesive-reversible-adhesives\" width=\"300\" height=\"300\" srcset=\"https:\/\/www.rct-online.de\/magazin\/wp-content\/uploads\/2020\/07\/elektro-leitfaehigkeitskleber-zweikomponenten.jpg 300w, https:\/\/www.rct-online.de\/magazin\/wp-content\/uploads\/2020\/07\/elektro-leitfaehigkeitskleber-zweikomponenten-150x150.jpg 150w\" sizes=\"(max-width: 300px) 100vw, 300px\" \/><\/a> <a href=\"https:\/\/www.rct-online.de\/en\/adhesives-and-lubricants\/adhesives\/one-component-adhesives\/31275\/pevicol-pvc-adhesive\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-5125 size-full\" title=\"PeViCol Adhesive for PVC | Ideal for Bonding Plastic Fittings, Pipes and Hoses\" src=\"https:\/\/www.rct-online.de\/magazin\/wp-content\/uploads\/2020\/07\/pevicol-kleber-fuer-pvc.jpg\" alt=\"pevicol-adhesive-for-pvc-reversible-adhesives\" width=\"300\" height=\"300\" srcset=\"https:\/\/www.rct-online.de\/magazin\/wp-content\/uploads\/2020\/07\/pevicol-kleber-fuer-pvc.jpg 300w, https:\/\/www.rct-online.de\/magazin\/wp-content\/uploads\/2020\/07\/pevicol-kleber-fuer-pvc-150x150.jpg 150w\" sizes=\"(max-width: 300px) 100vw, 300px\" \/><\/a><\/center><\/p>\n<p style=\"text-align: justify;\">However, adhesives based on nanostructures have the decisive disadvantage that their adhesion is not particularly strong. The polymer gel pHEMA, chemically poly(2-hydroxyethyl methacrylate) and based on snail slime, can provide a remedy here. In its moist state, the gel spreads across surfaces particularly well, much like natural snail slime. After drying, it assumes a glass-like structure that holds components together extremely effectively. If the bonding area is subsequently moistened again, the adhesive bond can be released and the components separated from one another. This effect of the detachable adhesive works on both smooth and rough surfaces \u2013 although such a reversible glue would be ineffective under permanently moist conditions. This mechanism also shows how reversible adhesives can be controlled by moisture rather than temperature.<\/p>\n<p style=\"text-align: justify;\">Nevertheless, this \u201chigh-tech adhesive\u201d can bond both very heavy materials and fine mesh structures in filters. Its cross-linked polymer structures and high molecular weight provide particularly strong adhesive properties and firm adhesive bonds. The future will show to what extent pHEMA can actually find its way into joining and fastening technology as a reversible adhesive.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Is_There_One_%E2%80%9CSuper_Adhesive%E2%80%9D\"><\/span>Is There One \u201cSuper Adhesive\u201d?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p style=\"text-align: justify;\">Many components in industry are already bonded today instead of being joined by riveting, <a href=\"https:\/\/www.rct-online.de\/en\/fasteners\/screws\">screws<\/a>\u00a0or welding, because bonding technologies are much easier and therefore more cost-effective to implement. In addition, bonding barely increases weight. In some cases, adhesives also perform additional functions. They can reduce the transmission of mechanical vibrations and act as electrical and thermal insulation. The concept of recycling also plays an important role in considerations regarding their use in adhesive technology. In this context, reversible adhesives are becoming increasingly relevant for technical design, maintenance and material recovery.<\/p>\n<figure id=\"attachment_5104\" aria-describedby=\"caption-attachment-5104\" style=\"width: 600px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-5104 size-full\" title=\"Gecko Adhering to a Glass Wall\" src=\"https:\/\/www.rct-online.de\/magazin\/wp-content\/uploads\/2020\/07\/reptilien-klettern-glas.jpg\" alt=\"reptile-climbing-glass\" width=\"600\" height=\"400\" srcset=\"https:\/\/www.rct-online.de\/magazin\/wp-content\/uploads\/2020\/07\/reptilien-klettern-glas.jpg 600w, https:\/\/www.rct-online.de\/magazin\/wp-content\/uploads\/2020\/07\/reptilien-klettern-glas-300x200.jpg 300w\" sizes=\"(max-width: 600px) 100vw, 600px\" \/><figcaption id=\"caption-attachment-5104\" class=\"wp-caption-text\">\u00a9 Voinakh \u2013 stock.adobe.com<\/figcaption><\/figure>\n<p style=\"text-align: justify;\">Whether the \u201cone\u201d super adhesive will ever be found \u2013 one that works on all surfaces, provides strong adhesion and is also reversible \u2013 remains an open question.
