The best adhesives for bonding metal and glass - overview + photo
Metal and glass are quite common materials that can be used for domestic purposes and industry. Often there is a need for gluing such materials, with which quite a lot of difficulties can arise.
For this, special substances and bonding technologies are used.
We offer to look at adhesives for gluing glass and metal.
What substance should you use?
At the very beginning, you should decide which specific substance should be used to combine both materials. How to glue glass and metal - this issue will be considered solely taking into account the characteristics of the selected adhesive.
They can be as follows:
Today, such adhesives have become quite popular because they are easy to use and make it possible to achieve very high results.
It is ideal for gluing glass and metal together. It should be noted that when decorating it is chosen very, very rarely, because it is black.
Glue a metal surface to a glass surface, or even vice versa, should be exclusively taking into account the main recommendations of the manufacturer.
Instructions in most cases will depend on which specific adhesive was chosen. In order to avoid serious mistakes, you should follow all the recommendations and rules.
Most attention is also paid to where exactly the resulting products will be used and under what conditions.
Among the main recommendations that relate to the use of almost all adhesives, the following points can be noted:
The heating temperature should be about +30 degrees Celsius. This indicator can be achieved only with the use of a building hair dryer, and it should also be taken into account that with a sharp increase or even decrease in the temperature level, the glass may crack, and for this reason the heating process should be carried out extremely carefully.
It is possible to speed up the drying of the adhesive by placing the product under the press. We must not forget also about the fact that the applied load must be evenly distributed, otherwise the glass will burst.
Transparent adhesive for glass and metal became popular as cyanoacrylate, i.
e. super glue. It can be used to create a wide variety of reliable pairings. Most often, a two-component version is used here for gluing metal, as well as glass. Its main advantages will be waterproof and quick drying.
Among the peculiarities of its use, other points can be noted:
At the time of gluing, ensure that the two surfaces fit tightly.
This will ensure the reliability of the connection.
In addition, different types of sealants can be used to achieve the task under consideration. It usually provides a high degree of butt insulation. it is for this reason that it is used when it is required to achieve not the highest degree of strength, but water impermeability. The procedure for bonding the two elements is not significantly different when using a sealant.
Among the features, it should be noted that the sealant may take longer to dry. Moreover, the resulting interface will have a lower degree of reliability.
Such a substance is characterized by the fact that it creates a soft layer that will withstand a slight displacement of the glued objects relative to each other, and after that will begin to regain its shape.
Among the features of use, the following points can be noted:
The instructions for use of the adhesive in question even indicate how long it takes to dry perfectly. Most often it will take several hours, but it takes much longer for 100% strength.
Automotive type glue
Automotive compound can be used as an adhesive for gluing glass and metal, and it is quite common on the market and it is also transparent.
When using it, high quality compounds can be added, and such an adhesive composition for metal and glass is used as follows:
It is necessary to ensure that the applied layer is uniform. Moreover, excess funds that come out should be removed immediately, because after hardening, they can create quite a lot of difficulties.
You can choose an adhesive of this type for joining a variety of products, but most often they are used when pasting a windshield. It should be borne in mind that a lot will depend on the quality of the gluing composition. It is for this reason that it is recommended to give preference to products from popular manufacturing companies.
Low quality products will lead to a fragile fit of one material on another, and after a while the degree of sealing of the joints will decrease.
The use of an ultraviolet lamp for gluing
In order to ensure a connection with high strength, it is worth using an ultraviolet lamp, which will be glued at times easier. They will be required in the case of using a special adhesive for metal and glass, for example, B-682-0 or VERIFIX MV 750. The first version should be used exclusively for transparent glasses.
Tips for UV lamp glue will look like this:
- Both surfaces should be cleaned and degreased before starting work.
You cannot use kerosene or gasoline for this, because such substances are ways to leave a thin film. On sale you can find special solvents for glass in liquid form.
- By means of a hair dryer, heat the glass, which will significantly increase the adhesion rate. In this case, it is recommended to reach a temperature of about +60 degrees.
- The adhesive should be applied in thin layers, and then the products to be joined will be applied to each other.
- Use the bonding lamp to irradiate the surface twice in succession. To begin with, the degree of connection will be 70%, and on the second, the strength will be increased to almost 100%.
The duration of the irradiation process in most cases will depend on what kind of lamp will be used for this. They will all be classified according to power ratings. The first stage of irradiation usually has a much shorter duration than the second.
