Intumescent Mastic Mercor Tecsel® (Internal use)
Tecsel® Intumescent mastics are intumescent sealants that are specially designed for joints in building construction and door frames, as well as small gaps in firebreak material. When exposed to fire, Tecsel® Intumescent mastic expands, preventing the spread of gases and limiting the increase of temperature through the various compartments of the building.
