What role does sealant play in the car?


What role does sealant play in the car? Nowadays, sealant mainly plays an important role in shock absorption, sound insulation, moisture resistance and dust prevention in the car field. Shenzhen Tensan will mainly talk about the four major roles of sealant in the car field.


1. The sealant plays the role of shock absorption in the car. If the elasticity of the car is not good, then in the use process, it will not only affect the comfort of the user of the car, but also because the lack of elasticity of the car accelerates the aging of the car and affects the life of the car. The application of sealant to car can effectively improve the elasticity of car and extend the life of car.


2. The sealant plays a role of sound insulation in the car. Compared with metal materials, the density of car sealants is small, but the physical molecules are large, and the molecular density is small after the glue is cured. Based on this characteristic, the sealant has a good sound insulation effect. If the car's sound insulation is poor, engine sound and external noise will be passed into the car. The use of sealant in the car can effectively isolate various noises from the engine and the outside world, and improve the comfort of car users.


3. The sealant plays a role in preventing moisture in the car. In summer and autumn, the air humidity is relatively large, if the car is not dense enough, then the moisture will enter the car along the gap of the car. The use of sealant on doors, glass windows, etc. can improve the overall sealing performance of the car and prevent moisture from entering the car.


4. The sealant plays a dust proof role in the car. If the car is not dense enough, dust will enter the car along the gap of the car. The sealant has good compaction performance and can improve the overall compactness of the car. And the plasticity of the sealant is very good, so that the sealant can be applied to glass windows, car doors and other parts.


The above-mentioned four important functions of sealant in the car field are precisely what determines its use in the car field. If you want to learn more, please contact Tensan for more information by email: Or you can visit our web at:,
