Fischer Intumescent and Acoustic Mastic is a one part water based Acrylic which is suitable for sealing joints and service penetrations in fire walls, drywall partitions, fire door frames, glazing systems and linear gap seals.

When exposed to fire, it reacts to form a highly insulative char that slows down heat transfer, as well as providing a barrier to fire.
