PP air filter is a very important part of the vehicle. It is responsible for filtering the impurities and dust in the air, preventing them from entering the engine, and protecting the normal operation of the engine. In the production process of PP air filter, welding is an essential link. However, the weld joint is prone to water erosion, resulting in a decline in waterproof performance. Therefore, how to achieve waterproof sealing at the weld seam has become a problem to be solved.

 In view of this problem, professional PP air cleaner manufacturers have developed a special waterproof sealant ENIENT EG1023, which can easily achieve the waterproof sealing at the weld. This kind of waterproof sealant uses a special formula, has good high temperature resistance, corrosion resistance, pressure resistance and wear resistance, can effectively prevent moisture penetration, to ensure the sealing performance of the welding place.

 The step of using PP special waterproof sealant for waterproof sealing is very simple. First, after the welding, when the weld is cooled to room temperature, clean the weld surface to ensure that it is clean and free of impurities. Then, the waterproof sealant is evenly applied to the weld, and slightly compacted to make it fully fit. Finally, wait for a certain time for the waterproof sealant to be completely cured. In this way, the weld joint can achieve a good waterproof and sealing effect.

 Compared with the traditional sealant, PP special waterproof sealant has better high temperature and corrosion resistance, can better adapt to the long-term use of air filter in high temperature and humid environment. Moreover, its bonding performance is also very good, it can be firmly bonded to the PP material, not easy to fall off, to ensure the lasting and stable sealing effect.

 When choosing PP special waterproof sealant, it is recommended to choose the products of the regular manufacturer to ensure the product quality and use effect. In actual use, it is also necessary to carry out the correct operation according to the requirements of the product manual, in order to give full play to the performance of waterproof sealant.

 In general, the waterproof sealing at the weld seam of the PP air filter is very important. The use of PP special waterproof sealant can easily achieve waterproof sealing, ensure the sealing performance of the welding place, prolong the service life of the air filter, and ensure the normal operation of the vehicle engine. Therefore, in the production and maintenance process of the air filter, the reasonable selection and use of PP special waterproof sealant is very important.
