Sealant plays an important role in the installation of doors and windows. The glass of doors and windows that were previously fixed with nails could easily be broken due to some vibration or impact. Therefore, people have noticed the importance of sealant that can fix the position of the glass and absorb vibration energy. Next, the editor of Lu's Chemical Industry will introduce to you the classification of door and window sealants.

Sealants for building doors and windows can be divided into elastic and non-elastic. Compared with non-elastic sealants, elastic sealants not only play a fixed (filling) role, but also have good elasticity and good substrate properties after curing. Adhesiveness, can withstand high environmental stress and large joint deformation displacement, and has excellent weather resistance and aging resistance, and plays the role of flexible connection, so it has a good bonding and sealing effect.
According to different basic polymers, sealants can be divided into silicone sealants, polysulfide sealants, polyurethane sealants, acrylate sealants, butyl sealants, neoprene sealants, asphalt caulking paste, and putty. Commonly used on doors and windows at this stage are: silicone sealant, polysulfide sealant, polyurethane sealant, acrylic sealant, butyl sealant.
