Many users are a little confused about the category and type of sealant labeled on the market, because many glass glue is the name of structural glue, in fact, some only doors and Windows sealant, simply can not reach the strength and resistance of structural glue, belong to the marketing concept products, general silicone adhesive, just add some anti-ultraviolet, anti-aging catalyst, Structural adhesive for safety performance and tensile, shear resistance requirements are relatively high, used in building curtain wall, steel structure, cement columns, Windows, containers, some simple room, iron sheet room, steel structure frame, want to use some good industrial structural adhesive, suitable for a variety of occasions, industrial assembly, electrical and electronic equipment......
The difference between sealant and structural adhesive 　　1. Different functions: structural adhesive is used for strengthening, bonding, repairing and so on; The sealant is used to fill the gap of the adhesive, but also played a sealing role.
　　2. The making principle is different: structural adhesive is easy to be squeezed out for use under temperature conditions; Sealant with talc powder and asbestos and other fillers, and then add some curing agent.
What is sealant?
　　Sealant, as the name suggests, is a kind of glue that can form a certain sealing space on the surface of the substrate. These base materials are very good in plasticity, which can not only deform with the shape of the sealing surface, but also not flow easily after coating. It can be said that it is a kind of sealing material with certain cohesiveness and certain firmness.
How to choose sealant?
　　No matter what kind of products people choose, they should follow certain methods of choosing. If you choose products randomly, it is likely to lead to the selection of products with short service life, or do not meet the needs of production.
First, we should pay attention to sealant manufacturers 　　In fact, the brand and the manufacturer of the product is the ID card and the specification of the product. A reliable manufacturer can guarantee the quality of the products it produces, and also can bring consumers a perfect after-sales service system. Guangdong sealant manufacturers, Bonte, Guangyan, Baiyun, Caft...... Dachang quality is often more trustworthy!
Two, followed by should focus on the sealing of sealant
　　Sealability is the primary characteristic of sealant, so people should pay attention to the sealing characteristics of sealant when choosing sealant. A good sealant has good sealing characteristics and can ensure that the sealant plays its due role in the appropriate environment. And the quality of the sealant does not have good sealing characteristics, in the sealing characteristics of a little worse, this sealant is obviously not able to meet a certain production needs.
3. Finally, attention should be paid to its weather resistance
　　If the sealant has certain weather resistance, then this sealant can maintain a long use effect in a lot of high temperature environment, has a certain use time, to a certain extent, save the cost of later replacement. Therefore, the selection of sealant should also choose some sealant with weather resistance characteristics.
The above are some of the selection of sealant should pay attention to the selection method, people only master a certain selection method, can choose the right products in a wide variety of commodities, avoid the later rework.
