And what properties determine whether a bond lasts or fails quickly?<\/p><p>Here are the most important facts about the fascinating world of adhesives:<\/p><p><strong>1. Adhesion<\/strong><br \/>The most important property of an adhesive is its ability to adhere to surfaces. This process is called adhesion.<\/p><p>For an adhesive to adhere well, the surfaces must be<\/p><ul><li>clean,<\/li><li>dry<\/li><li>and as even or slightly roughened as possible<\/li><\/ul><p>Note: The better the adhesive can \u2018wet\u2019 the surface, i.e. the better it can spread, the stronger the subsequent adhesion will be.<\/p><p><strong>2. Cohesion<\/strong><br \/>Cohesion &#8211; the internal strength of the adhesive itself &#8211; is at least as important as adhesion to the surface. An adhesive must not only adhere to the materials, but also remain stable within itself. Depending on the application, different cohesive properties are required:<\/p><ul><li>Hard and rigid: for structural bonds &#8211; e.g. in the automotive industry<\/li><li>Soft and elastic: for flexible bonds &#8211; e.g. in textiles<\/li><\/ul><p>\u00a0<\/p><p><strong>3. Curing mechanisms<\/strong><br \/>Adhesives cure in different ways:<\/p><ul><li>Physical: by evaporation of solvents (contact adhesives) or cooling (hot adhesives)<\/li><li>Chemical: by a reaction, for example with humidity (instant adhesives) or by mixing two components (epoxy resins)<\/li><\/ul><p>\u00a0<\/p><p><strong>4. Temperature and chemical resistance<\/strong><br \/>Not all adhesives are equally robust. Some dissolve quickly when exposed to heat, for example. In this context, it is important to note<\/p><ul><li>Temperature resistance: Some industrial adhesives still work reliably even at over 200\u00b0C.<\/li><li>Chemical resistance: Certain adhesives are insensitive to oils, solvents or acids.<br \/>Such high-performance adhesives are indispensable for applications in aviation, automotive engineering or medical technology.<\/li><\/ul><p>\u00a0<\/p><p><strong>5. Elasticity and rigidity<\/strong><br \/>Depending on the task, an adhesive must be flexible or extremely rigid.<\/p><ul><li>Elastic adhesives compensate for movements or vibrations &#8211; ideal for components that expand or contract with temperature changes<\/li><li>Stiff adhesives offer high strength and precision &#8211; for structural bonding in cars or aeroplanes<\/li><\/ul><p>The trick is to find the perfect balance depending on the material pairing and load.<\/p><p>\u00a0<\/p><p><strong>Conclusion<\/strong><br \/>There is a lot of science and technology behind the seemingly simple act of bonding. Depending on the requirements, modern adhesives can be<\/p><ul><li>extremely resilient,<\/li><li>highly flexible,<\/li><li>heat and chemical resistant<\/li><li>and particularly sustainable.<\/li><\/ul><p>Bonding technology offers solutions where mechanical connections reach their limits.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-3a06759 elementor-widget elementor-widget-spacer\" data-id=\"3a06759\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"spacer.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<div class=\"elementor-spacer\">\n\t\t\t<div class=\"elementor-spacer-inner\"><\/div>\n\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-8b589ea e-flex e-con-boxed e-con e-parent\" data-id=\"8b589ea\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t\t<div class=\"e-con-inner\">\n\t\t\t\t<div class=\"elementor-element elementor-element-48a0c11 elementor-widget elementor-widget-text-editor\" data-id=\"48a0c11\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p><strong>If you have any questions, please get in touch with your account manager or contact us here:<\/strong><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-dcb0daf e-flex e-con-boxed e-con e-parent\" data-id=\"dcb0daf\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t\t<div class=\"e-con-inner\">\n\t\t\t\t<div class=\"elementor-element elementor-element-49c5b00 elementor-widget elementor-widget-button\" data-id=\"49c5b00\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"button.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<div class=\"elementor-button-wrapper\">\n\t\t\t\t\t<a class=\"elementor-button elementor-button-link elementor-size-sm\" href=\"mailto:info@wagmbh.com\">\n\t\t\t\t\t\t<span class=\"elementor-button-content-wrapper\">\n\t\t\t\t\t\t\t\t\t<span class=\"elementor-button-text\">Request<\/span>\n\t\t\t\t\t<\/span>\n\t\t\t\t\t<\/a>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"<p>What makes an adhesive?
