Mercor Tecsel® foam, fire resistance up to 240min
Tecsel® Foam is a self-expanding, single-component polyurethane highly fire resistant.
Tecsel® Foam 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® Foam expands, preventing the spread of gases and limiting the increase of temperature through the various compartments of the building.
Fire resistence achieved depends on the size of the joint and the characteristics of the gaps to seal.
