For most cars, the seal used on the car is extruded with epDM. Rubber performance and indicators are not the same as the service life of the seal is not the same, now let's talk about the use and maintenance of epDM rubber seal:

1, check the sealing strip for large cracks and fractures. If the seal breaks, it can be repaired with adhesive. The use of sealing strip special adhesive, it is easy to patch the large cracks. Of course, if the seal damage is serious, or the aging degree is large, it is best to replace the new seal to save trouble.

2, the owner of the car in the use of detergent to clean the door and window sealing tape, the best coated with a layer of high permeability protective agent, so as to prevent the aging of the sealing strip and can greatly improve the sealing strip sealing. In addition, dust can easily fill up between the gaps in the seals, causing corrosion. To this end, you should clean up the dust with a brush.

3, in the replacement of the whole body, should be in the weld lap part of a layer of sealant, the thickness of the adhesive layer should be about 1mm, and the adhesive layer shall not have virtual stick, bubble and other defects. 3mm-4mm elastic coating and anti-corrosion coating shall be applied to the entire floor and front wheel cover. These measures can not only greatly enhance the vehicle sealing and slow down the speed of corrosion body, but also greatly improve the ride comfort.

4. The sealing of the door and the body is a difficult part. The sealing requirements are strict, and the part that should be sealed is longer. In the advanced car is often set up 3, 4 sealing, installation of the front pillar and the roof side beam of the four-fold sealing structure. This multi-channel seal is generally arranged in the front door seam, in addition to the sealing function, and the role of car sound insulation noise reduction.

5. After the window glass is damaged, the owner should check whether the sealing strip is damaged when changing the glass. Because the window after repair is often restored to the original shape, therefore, at this time in addition to ensure that can easily pull or lift the car window glass, but also pay attention to the window glass around the sealing. If the gap between the glass slots is uneven, the rubber strip and the glass, the glass trough contact is poor, the owner can easily pull off the sealing strip by hand.

6, the owner of the car in the roof, should be in the roof around the pressure of a layer of conductive sealant, to be welded and then in the flow tank and seams coated with flanging adhesive, which not only helps to seal the body, but also to prevent the body due to flanging weld water and early rust.

7. Sunroof is the basic configuration of most family cars. When the car sunroof is opened, the rubber sealing strip track is exposed to the air, which will inevitably accumulate dust and even run into small gravel. Prolonged use can cause the skylight to deform due to wear and tear and block the drain hole. Therefore, it is very important to clean the track regularly and apply lubricating oil for the track.

Automobile sealing tape is a small part of the body, but it can ensure that the door of the switch is stable and thick, but also make the car weather, dust, heat insulation, sound insulation, to the edge of the doors and Windows to play a decorative effect. When the body is vibrated and twisted, the sealing strip also plays a role in buffering, absorbing shock and protecting glass. Car maintenance is no small matter, any link can not be ignored.
