Did you know that sealant has better elasticity

The correct treatment method can use a sharp tool to wash the water seepage point wider, and then clean the one that needs to be glued until the wall is dry. After the wall is dry, it can be applied with neutral weather resistant adhesive, which should be a good solution to the problem of weak bonding caused by water leakage. It is also worth mentioning that we can't use acid glue for silicone sealant, because this kind of glue will cause corrosion to the expansion screw.

First of all, this silicone sealant product plays a very important role in many component bonding, that is, it needs to have good tensile and shear resistance ability, so that it can play a better and solid role in use, and the time used in component bonding can be longer.

Sealant also has a better ability of elasticity, because when it realizes the bonding of components, it also needs to complete the bonding effect on the surface of different base materials of components. If the sealant has no elasticity, it will also have a great impact on the bonding of components, so the characteristics of its personality are very important.

Sealant generally refers to silicone adhesive, which is not used to stick paper, so sticking paper and non sticking paper will not affect the actual use; however, sticking paper is related to some characteristics of paper and glass adhesive. Firstly, different materials and textures of paper have a great impact on sticking paper. If paper fiber is loose, glass adhesive is easy to wet the paper, so as to stick paper; secondly, glass adhesive also has an impact, preliminary analysis and Curing speed has a certain relationship, such as low-grade adhesive curing slow, easy to stick paper.

Because of its fast curing speed, the adhesive does not completely infiltrate the surface of aluminum, that is, it can not penetrate into the pores of the substrate surface without sticking. This phenomenon does not affect the normal use of glass adhesive. There are two main types of high-grade glass adhesives. One is large glass curtain wall or point curtain wall. When glass adhesive is used here, it only contacts glass and does not contact with other materials, so it does not matter if it does not stick to aluminum materials. The other is used for filling joints of glass aluminum alloy doors and windows. Glass adhesive is used for filling joints between glass and aluminum alloy. Although the adhesive force between glass adhesive and aluminum alloy is not good, it is not good because of good bonding to glass. It will fall off, and it is used as caulking seal without bearing load (i.e. no force), so as long as it can adhere to the aluminum alloy, it can play a sealing role.
