Silicone is often used as seals or gaskets due to its flexibility and ability to be compressed between two surfaces.\u00a0 Other uses include flexible medical devices and tubing, prosthetics, surgical implants and special effects in the film industry. Thanks to its high temperature resistance, it is becoming popular in the kitchen for items such as non-stick bakeware and molds. Maybe the \u201cnon-stick\u201d is a bit of a clue when it comes to trying to <a href=\"https:\/\/permabond.com\/materials_bonded\/how-to-bond-silicone\/\">bond silicone<\/a> material.<\/p>\n<p>In its solid, cured state it is normally very flexible, stretchy and\u2026 hard to bond!<\/p>\n<h2>Surface Preparation<\/h2>\n<p>There isn\u2019t much you can do to improve the surface of the silicone. It is always going to have plasticizers migrating to the surface to add to bonding woes! A solvent wipe with isopropanol will prepare the surface for bonding and remove any processing lubricants present and give a consistent bonding surface. Acetone can be a bit aggressive, and other cleaners, such as meths or white spirit can leave a residue.\u00a0 Always make sure all solvent evaporates fully before bonding!<\/p>\n<h2>Adhesive Selection<\/h2>\n<p style=\"text-align: center;\"><a href=\"https:\/\/permabond.com\/wp-content\/uploads\/2023\/04\/2011-Rubber-Bonding-1-1.jpg\"><img fetchpriority=\"high\" decoding=\"async\" class=\"wp-image-724 alignleft\" src=\"https:\/\/permabond.com\/wp-content\/uploads\/2023\/04\/2011-Rubber-Bonding-1-1.jpg\" alt=\"2011 Rubber Bonding 1\" width=\"295\" height=\"221\" \/><\/a><\/p>\n<p>This is quite a short section because there are not many industrial adhesive options available to a poor soul looking to bond silicone! Silicone-based adhesives tend to work well on silicone. However, if you are looking for a fast cure and to get away from isocyanate chemicals, options are limited. Prime the silicone&#8217;s surface with polyolefin primer such as <a href=\"https:\/\/permabond.com\/tds\/pop_tds-en\/?pdf=1\">Permabond POP<\/a>, and then parts bond the parts with a <a href=\"https:\/\/permabond.com\/products\/cyanoacrylate-adhesives-2\/\" target=\"_blank\" rel=\"noopener\">cyanoacrylate<\/a>. <a href=\"https:\/\/permabond.com\/tds\/2050_tds-en\/?pdf=1\">Permabond 2050<\/a> is a favorite for bonding silicone as it is flexible. It doesn\u2019t affect the \u201cfeel\u201d of the silicone \u2013 it can be very hard to detect the bonded joint as it remains soft like the parent material \u2013 this is great for seals and o-rings as you don\u2019t end up with a \u201ccrunchy\u201d hard bit.<\/p>\n<p style=\"text-align: left;\">To receive further information about the products recommended, please\u00a0<a title=\"Contact\" href=\"https:\/\/permabond.com\/contact-us\" target=\"_blank\" rel=\"noopener\">contact\u00a0<\/a>Permabond.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Silicone Bonding Silicone rubber is a high performance elastomeric material.\u00a0 It has a wide variety of uses.
