Acrylic Based Intumescent Mastic - in White, Brown or Grey


Pyromas A is an intumescent sealant combining water-based acrylic emulsion with fillers to provide high levels of fire resistance in a range of building applications.

The one-part sealant is solvent free and when subjected to fire, a chemical reaction forms a safe, inorganic meringue, which provides proven fire sealing in building joints incorporating concrete, wood and metal.
