The optimal match between the beginning of the reaction and hardening enables sufficiently long work interruptions, as well as fast work progress, for the user of the fire protection foam, which is intumescent in the event of fire. The high material viscosity prevents the foam from running out of the component opening. With the system, ZZ-Fire protection foam 2K NE, mixed penetration seals up to EI 90 or cable penetration seals up to EI 120 can be produced.
After the end of the reaction, the permanently elastic structure of the penetration seal enables easy retroactive-installation. Retroactive installations can simply be poked through the existing foam. Gaps that occur due to removal of cables or pipes can easily be refilled with the ZZ-Fire protection foam 2K NE.
If the fire resistance classes EI 60 or EI 90 are required, the ZZ-Fire protection foam 2K NE suffices as a “one-product solution”. No additional material components or work steps are necessary.
