New automotive materials from Momentive debuting at K 2022 include dark gray LSRs, which are appropriate for the production of seals in the intake area of combustion engines, as well as for seals and O-rings for use in sensor technology and in the drive area of electric vehicles (EVs) requiring flame resistance. They are being integrated into a new technology portfolio called NevSil.
In addition to the materials for making parts, Momentive will exhibit materials used to finish parts. The scratch- and weather-resistant protective coatings in its Hardcoats division are designed to be applied in an ultra-thin layer to the surface of automotive exterior plastic parts to protect them against damage from mechanical and chemical stresses, as well as the sun. The coatings can be used on parts related to lighting, decorative trim, sensors and the front modules featured on EVs in lieu of classic radiator grilles.
Several new coatings are available:
• SilFORT AS4700-SP1 spray-on clearcoat protects clear and black PC exterior automotive parts, like EV front-end modules, from scratches, abrasions and weathering.
• SilFORT UVHC5000K1 is the latest generation of UV-curable protective clearcoat for automotive exterior applications. It meets key global regulations for automotive headlamp applications.
• SilFORT TAC2000 anti-fog coating prevents condensation from building up on the inside of headlamps and sensor covers.
• Momentive introduced the UV curable clearcoat, SilFORT UVHC7400 UV-curable clearcoat protects interior parts and displays from damage caused by scratches and chemicals. It be applied by traditional methods, such as dipping or spraying, but also by digital Ink-jet printing — a newer approach.
The company will display its wares in Hall 6, Booth B15.
