Maybe you haven't understood that the texture and comfortable experience of driving are closely related to an invisible layer of "glue". During the journey, it can provide personal protection and escort for your car.
With it, you can run flat even on bumpy roads. Even if the annoying noise outside the window is constant, the car can still be quiet and quiet; without it, the car may bounce and vibrate when it encounters uneven roads and pass noisy roads. The speech in the car may depend on howling, and the ride becomes a torment.
So, what is this invisible "glue"? In fact, sealants are used in many parts of the car. Because the rust prevention and sealing of the car are directly related to the comfort, aesthetics and even the life of the car, if the rust prevention measures are not appropriate, the car body will rust or even perforate in a short period of time. Therefore, after the car is painted, it is necessary to seal the joints with a highly effective anticorrosive and good sealing agent, including spraying the sealant on the chassis, so as to relieve the impact of the sand and gravel raised by the car at high speed on the chassis; Reduces interior noise, improves passenger comfort, and enhances corrosion resistance of the chassis.
With the development of automobile manufacturing in the direction of energy saving, environmental protection, safety and comfort, and low cost of life, higher requirements have been put on the use performance and process performance of automotive adhesives. Favored.
PVC plastisol for vehicles is currently the most commonly used automotive sealant. It is mainly used for welding seam seals and underbody coatings. It is often used for spraying on the bottom of the car, wheel covers and fenders to prevent corrosion of the car body and prolong the life of the car body. .
However, the production of PVC plastisols for automobiles requires high-temperature baking. The longer the time required, it means energy waste and unavoidable VOC emission pressure. In recent years, as the Chinese government has formulated stricter environmental protection regulations and policies, OEMs are facing environmental protection pressures of energy saving and low VOC emissions, and they have also tested the innovation capabilities of suppliers.
Evonik's NOURYBOND® family of products has always led the market trend of automotive plastisols to provide customers with the best solutions. Different NOURYBOND® products can meet the technical requirements of different OEMs and different baking processes, and provide good adhesion on the surface of different substrates.
"NOURYBOND® 382 is a new generation of tackifiers developed by Evonik based on German technology platforms. As a new member of the NOURYBOND® family, it has been marketed and won the trust of customers with its excellent performance. PVC based on NOURYBOND® 382 Plastisol can make your car's chassis better anti-stone impact, reduce noise, waterproof and anti-corrosion, and improve ride comfort. "
Dr. Yan Zhenlong, technical manager of Evonik's crosslinker business line, said, "This product has many advantages, including light color, low odor, and the product does not contain any phthalate and aromatic plasticizers. Equipped with a variety of baking processes, it has a good match with colored paints and is suitable for new energy vehicles. At the same time, this product has the characteristics of fast bonding under low temperature and short time baking environment, thereby improving production efficiency, Energy saving."
