Environmental Trends of Silicone Sealant

2021/02/15

With the rapid development of China's economy and the continuous improvement of people's living standards, the requirements for the building environment are becoming higher and higher. In addition to meeting its basic use functions, people more concern about its quality and beauty. Meanwhile, people began to pay attention to the topic of energy conservation and environmental protection.

As doors and windows play a great role in the building industry, its function of energy saving and environmental protection will directly affect the use effect of the users. Moreover, as one of the important materials for the waterproof sealing of the doors and windows, silicone sealant plays a decisive role in the use effect of the doors and windows.

At present, silicone sealant for doors and windows is mainly a one component which will handle easily, and according to the small molecules released during the reaction,it can be divided into acetic silicone sealant and neutral silicone sealant. However,when the acetic silicone sealant is under curing, it will release acetic acid and create strong smelling, and it will corrosion to metal materials.But for neutral silicone sealant, it avoids the disadvantage of the acetic one, so its application scope is more wider.But everyone should know about that no matter for what kind of silicone sealant, it is harmless for human body after it totally cured.

In general, silicone sealant is characterized by its excellent weather resistance and environmental protection. However, in order to reduce the cost of raw materials,many manufacturers in the industry reduce the content of 107 glue(basic polymers in silicone sealant), add mineral oil to sealant for replacing silicone oil and other components, so the quality of sealant is reduced, and then the weatherproof ability and durability are reduced. The low price silicone sealant is easy to harden, crack in the process of use, which leads to the later renovation and rectification, resulting in more waste of resources, and is not suitable for the door and window sealing of environmental protection requirements.

Therefore for this situation, it causes our reflection and then takes actions. As for silicone manufacturers, they should aware that except meeting the basic performance index, silicone sealant should be used to carry out the corresponding environmental protection requirements according to the actual application requirements. Fast curing, extensive adhesion, environmental protection performance, green evaluation system of production plants are the future development trend of silicone sealant for building doors and windows.

For now, we would like to introduce our brand-new CHNGOO product--CHG-201 POLYURETHANE SEALANT to all of you. With the novel design, CHG-201 is a one-component moisture-curing polyurethane sealant with excellent sealing property and good adhesive ability. Environmentally-friendly, and no corrosion and no pollution to basic materials and it mainly applies in the scene of sealing and maintenance of car windshield and side window glass. Also it is easy to cut, convenient for secondary maintenance. If it needs your meet your needs, welcome to inquiry!
