Light resistance test cleared! Prolonged lifespan achieved by adding UV-absorbing components to the IMD surface foil.
No material change is necessary. UV-absorbing components will be added to the double in-mold surface foil, and it will pass the light resistance test.
In cover lenses and automotive exterior panels, light stability that prevents yellowing and appearance deterioration due to long-term UV exposure is required. Yoshida Techno Works has established a method to incorporate UV-absorbing components into the surface film (surface foil) in the double in-mold process, granting light stability functionality simultaneously with molding. Since post-molding painting and coating processes are unnecessary, we achieve process reduction and cost reduction while passing light stability tests. In addition to our application results for BC7/VG4 cover lenses for Fujitsu Plastics/Rhythm Shoei, we also have a track record of proposing and passing tests for weather-resistant foils for automotive parts (K0F) for Honda Motor Co. The formulation of UV-absorbing components and film selection can be customized according to product requirements and testing standards.
