epoxy resin structural adhesiveTypes of Strong Metal Adhesive:
There are many types of adhesives used to bond metals, including metal AB adhesives, resin based metal adhesives, metal instant adhesives, metal repair agents, etc,
Application of metal adhesive:
Mainly used for self-adhesion and mutual bonding of metals such as iron, stainless steel, steel, aluminum, aluminum alloys, lead, and alloy metals. Some of the strength can achieve the effect of replacing welding. Swiss DM glue has passed the EU REACH 191 test and meets environmental standards; Click to apply for trial glue (limited to the top 30 per day). Before purchasing strong glue, consult the glue manufacturer for DM glue samples;
Attention to issues when bonding metal with metal adhesive:
Adhesive Warm Reminder:
Most of the adhesives used for bonding transparent plastics to metals are thick and can be diluted with an appropriate amount of ethyl acetate before use. Adhesive manufacturers and companies have specialized adhesives for metals;
1、 Adhesive bonding between plastic and metal:
The surface of the object to be adhered should be clean and dry. Oil stains and other substances can be cleaned with gasoline solvent. Apply the adhesive solution evenly to the surfaces of the two objects to be adhered, wait for 3-6 minutes, and align the two objects to be adhered. Apply a little pressure to make the adhesive surface denser, and let it sit for a few hours. After 48 hours, it will be completely cured; For materials that require high adhesion to metals, hard plastics, etc., iron sandpaper or other materials can be used to roughen them. Two coats of glue (wait for a few minutes after one coat of glue before applying the second coat, and then dry and close it slightly) have a better effect.
2、 Mixing ratio of metal adhesive:
This is for metal AB adhesive, because metal AB adhesive is a type of adhesive commonly used for bonding metals, which needs to be mixed before curing. The mixing ratio is mostly 1:1 by weight. To achieve the desired strength, this step is very important and requires strict mixing according to the ratio. Too much or too little A or B agent can affect the strength of metal AB adhesive. When manually mixing, special attention should be paid. If the mixing ratio is difficult to control, it can be replaced with tubular packaging and used with adhesive tools to achieve automatic mixing and save the mixing process.
3、 Metal glue does not need to be applied too much or too thick, the key is to apply it evenly:
When using metal adhesives, the more you apply, the higher the bonding strength. This not only wastes glue, but also causes too much metal adhesive to be applied, resulting in a worse bonding effect. This is because metal adhesives need to be in contact with air to cure, and the amount of water applied is too much. After a period of time, only the surface metal adhesive will cure, and the internal curing will not be complete. Metal adhesives that have not been completely cured are easily detached under external force; So when using metal adhesives, it is necessary to control the amount of glue applied, without applying too much or too thick. The key is to apply it evenly.
4、 How to improve the adhesion strength of metal surface smoothness:
The bonding of metal adhesive is achieved by immersing and filling the visible or invisible fine crevices on the metal surface, and curing it through the tensile force of the adhesive itself. If the metal surface is very smooth, the metal adhesive is like a tree with nowhere to root and cannot work; So for smooth metal surfaces, roughening and cleaning before applying glue can greatly improve the bonding strength of the metal adhesive;
5、 The cleanliness of the metal surface affects the bonding effect:
If there are rust, dust, oil stains, etc. on the metal surface, it can be polished, cleaned with industrial alcohol based chemical solvents, and dried before applying glue. Also, if the metal surface has been sprayed with paint or ink, it means that the metal adhesive and the paint or ink are bonded together. If the adhesion of the paint or ink is poor and the paint or ink falls off, the metal adhesive will also fall off, and some metal adhesives will corrode the paint or ink.

Someone asked if AB glue can bond metal
AB glue has a special adhesive for metal bonding, and general AB glue cannot bond metal. AB glue is another name for two liquid mixed hardening glue, one liquid is the main glue and the other liquid is the hardening agent. The two liquids need to be mixed together to harden, and it does not need to be hardened by temperature. Therefore, it is a type of room temperature hardening glue that is sometimes used in modeling. Generally used in industry. AB glue is the name for two-component adhesive. AB adhesive with ingredients such as acrylic acid, epoxy, polyurethane, etc. is available on the market. When used in the factory, the toothpaste tubes are packaged with AB glue (prominently labeled on the packaging box) made of epoxy resin to distinguish them from conventional large cans (1kg/2kg set).
