What Is The Best Epoxy Adhesive Glue For Metal To Metal?
Metals can be joined together using adhesives and without fixings and welding. It may sound impossible, but it is possible thanks to three main types of adhesives developed tough and superior to make metal-to-metal bonding easy and reliable. The three adhesives that can be used to achieve this kind of bonding are super glue, polyurethane adhesives, and epoxy resin glue.
Epoxy, however, stands out as the best metal glue. This is because the adhesive has incredible tensile strength and can resist high temperatures. You have no worries, even when the metal you are joining is used in areas with extreme temperatures. Epoxy resin can resist up to 260 degrees Celsius of heat. Epoxy adhesive for metal is usually soft and putty-like, but once it hardens, it creates a durable, strong layer binding the metals solidly. The layer is also resistant to corrosion, chemicals, and moisture; it is waterproof and non-toxic, making it a good choice even for outdoor metallic items.
Epoxy glue takes time to dry and cure completely, and you also will be required to apply pressure to the two pieces you are joining for up to an hour for the bond to come out perfectly. Once applied, the adhesive should be left to dry and cure for up to 24 hours before it is considered ready to be used. The glue is also suitable for most metal bonds because of its high tensile strength; it is not fragile and creates strong bonds with the assurance of not shifting during use. The layer can be sanded down to achieve the desired design and can also be drilled into shape using a file or machine.
But even with all these epoxy qualities in mind, it is still important to consider a few factors when looking for the best epoxy adhesive for metal. Some of the things which can guide you to the right product are:
Metal type – It is important because metals are of different forms, so an adhesive that works amazingly on aluminum may not be as good for cast iron. Always choose an adhesive with the right tensile strength matching the metals you work with. Most manufacturers will indicate this on their products, so check before purchasing.
Bond load – You are creating the bond for a reason, making it important to check whether the bond will comfortably bear the load it is created for. Using the wrong adhesive will break the bond once the load is on. Choose an adhesive to create a bond strong enough to hold under pressure.
Surface structure – Some metals, like aluminum, need an allowance for recurring oxidation, whereas some surfaces are too smooth for the adhesive to hold and hence require smoothening before the application. Always ensure you are fully aware of the structure of the metal surfaces you work with so you can choose an adhesive that won’t disappoint.
