Hygienic design freedom

The fantastic thing about this solution: You get to enjoy almost unrestricted design freedom. Whether high-gloss, Shy Tech design, backlighting, or special graphic requirements: IMD BIOFENSE allows a wide variety of creative paths. This is because its bacteria protection integrates invisibly into the surface design. Even the functions of capacitive sensor fields or antennas remain unimpaired. The product is applied using cost-effective In-Mold Decoration (IMD), whereby the component is manufactured and decorated in a single work step. For two-dimensional surfaces, hot stamping is an efficient solution. KURZ BIOFENSE® is harmless to health. This creates an impressive symbiosis of hygienic finish, functionality, and cost-effectiveness.

Protection for a wide range of living areas

This protective layer ensures that a microbial biofilm forms. Owing to its deposit effect, this action lasts for a long time. KURZ BIOFENSE® is suitable for almost all areas of life. This innovation is particularly useful for products that are frequently touched, such as mobile devices, light switches, but also cosmetics jars or interior fittings in cars.
