What are the characteristics of structural adhesive?

In order to understand the code difference of Structural Adhesive, we should first make clear the characteristics of structural adhesive. Find out which structural adhesives are used in which places. Because for structural materials, there are many commonalities. To this end, I will give you a summary of the characteristics of structural adhesives, which can be understood through the following four aspects.
① The essence of structural adhesive. The essence of structural adhesive refers to the adhesive that can be used to connect structural parts. Therefore, structural adhesive usually refers to an adhesive with high strength, which can bear a very large load, and can resist aging, fatigue and corrosion at the place of use, and can bear a strong force within its specified period of time. Among them, the compressive strength of structural adhesive is greater than 65MPa, the connection strength is greater than 30MPa and the shear strength is greater than 18MPa, which are the basic parameters of structural adhesive.

② Common uses of structural adhesive. Structural adhesives are developing very rapidly at present. And what we often see is actually building structural adhesive. Building structures are generally used in construction, installation, decoration, sealing, structure, bonding and other related areas. For example, the most common in buildings can be used for glass installation, steel bar planting, steel plate sticking and so on.
③ Advantages of structural adhesive. The strength of structural adhesive is very high, and the peeling resistance and impact resistance of structural adhesive after solidification are very excellent, and the construction is very simple. Therefore, structural adhesive can be used to connect the same kind of materials, such as metals, ceramics, plastics, rubber and wood, or between different kinds of materials. As at present, structural adhesive can replace welding and bolt connection to a certain extent. Because the stress distribution during the connection of structural adhesive is uniform, it has almost no influence on the connector.

④ Classification of structural adhesives. For structural adhesives, they are generally divided into different types according to the different parts of use. For example, our common structural adhesives can be divided into high-performance silicone structural adhesives and neutral silicone structural adhesives. Actually, it is the neutral silicone structural adhesive mentioned here. Generally speaking, it refers to the glass glue we use indoors, while the high-performance copper silicate structural glue is generally used for curtain wall connection. We can also distinguish different types of structural adhesives by their colors.
