When deciding to glue metal to any other surface, you must take into account several factors at once, on which the success of your venture will depend. Of course, you will need special glue, but the structure of the materials to be glued and the sequence of your actions in the process of work will play an important role.
Instructions
Step 1
Not every glue is suitable for gluing metals. Therefore, please read the attached instructions carefully or consult your dealer when purchasing. If, for example, you need to glue metal to rubber, then look for an adhesive that works with both of these materials, not just one of them.
Step 2
Besides, metal is different from metal. If two raw aluminum parts are not so difficult to glue together, then steel will have to tinker a little.
Step 3
For most metals, it is best to buy a two-component epoxy based adhesive, and for stainless steel, you should choose methyl acrylate adhesive.
Step 4
There is no single instruction for gluing metals. Some are better to glue in a dotted way, for some you will have to squeeze a strip of glue out of the tube, and for large planes there is a special glue that needs to be smeared with a thin layer on the surfaces to be glued.
Step 5
But in all cases, the metal will have to be freed from dirt and grease before work. This will significantly improve the quality of the gluing and extend its service life.
Step 6
After cleaning the parts with fine-grained sandpaper, apply glue to them as written in the instructions, press them well together and leave for a while for the glue to set.
Step 7
Some types of adhesives hold much better if you give them a so-called "hot set". Just place the glued parts on a baking sheet of the oven and leave them at 90 ° C for 3 hours. But you can do this with the glue, the instructions for which indicate its good tolerance to high temperatures.
