In everyday life, we often encounter the need to glue various surfaces. And many are concerned about the question "how to stick metal to metal?". This problem is especially relevant for those joints that cannot be fastened with welding or riveting. What to choose?
Choose the composition correctly
To begin with, it is worth remembering that the adhesive composition for bonding two metal surfaces should be selected especially carefully. Modern manufacturers offer compositions based on one or two components, depending on which the scope of their application varies. Many people think about what kind of glue glues metal. There are quite a lot of answers to such a question, since a lot of funds are issued today. Whatever composition is used, the following is important:
- properly prepare the surface of the material, that is, clean it;
- competently choose glue and evenly distribute it on surfaces, strengthening the design where welding can weaken.
Thanks to the rapid development of modern technology, finding a way to connect metal parts is quite simple. You can use the method of industrial assembly using threaded connections, welding or riveting.
Surface preparation is an important step
Before sticking metal to metal, you need to take care of the preparation of surfaces, namely their washing and thorough drying. If, in addition to chemical degreasing, the surface is also cleaned with solvents, then dirt can be removed by mechanical treatment with brushes and cleaning cloths. Very often, oxide films accumulate on the surface, such as rust, which cannot be dealt with by degreasing. In this case, you can first mechanically clean the metal surfaces, degrease them and only after that proceed with gluing.
How to glue metal to metal: a review of tools
One of the most popular formulations available under the Dublfix brand is a versatile double - sided tape. This is an innovative material that allows you to glue metal with any surface - metal, wood, plastic and so on. The peculiarity of adhesive tape is that it allows you to fasten even uneven and curved sections firmly and securely. DublKote adhesive tape is also ideal for metal bonding: thanks to the foam material that underlies the tape, it can take the form of any surface, while filling all the recesses. Excellent traction also speaks in favor of choosing this tool.
Choosing how to glue glass to metal, pay Attention DUBLFIXHIGHBOND high-strength double-sided adhesive tape . Both of its surfaces are treated with universal acrylic adhesive , which contributes to excellent adhesion to a wide range of surfaces. High resistance to humidity and temperature extremes allows the use of tape in both indoor and outdoor applications.
Two metal surfaces can be glued using Permabond adhesives. They allow you to connect any materials, while the connection is strong and reliable. The glue is evenly distributed, so even the joints are ideally even and smooth. The seam will be airtight, and therefore you can not worry that corrosion will occur. This material is based on methyl cyanoacrylate, through which a number of materials can be bonded. If you need to apply the product accurately and accurately, you can do this not manually, but using automated devices.
The use of epoxy resins
As an adhesive for bonding metals, epoxy resins, which consist of two components and are mixed into a polymer, can also be used. They will be distinguished by high strength characteristics of the adhesive joint, which allows the use of the composition for any type of metal surface. At the same time, it is resistant to wear and moisture, and also shows excellent physical and mechanical properties. Today, manufacturers offer a wide selection of combinations of epoxy resins, and for each purpose you can choose a specific composition.
You can also glue metal to metal with the help of Super Epoxy Metal glue. Its feature is that it is possible to use the composition for joining iron, aluminum, steel, copper and other surfaces. The epoxy base ensures that bonding is reliable and durable, while the seam will not shrink or expand. Such a tool is used very simply, but before sticking metal to metal, you must first thoroughly clean the surfaces using gasoline or acetone. The resin should be squeezed onto one surface, the hardener onto the second, mix them thoroughly. Then the surfaces should be neatly joined.
Application rules
Most adhesives require a number of precautions. So, you need to use gloves and avoid getting the composition not only in the eyes, but also on the skin. If, nevertheless, the glue gets on the surface of the hands or eyes, rinse them thoroughly with water. Do not use a product whose expiration date has passed.
