Firemastic 300 Acrylic Sealant intumescent is a one part acrylic emulsion that is designed to resist the passage of fire, smoke and sound. FireMastic-300 will intumesce and form a char when exposed to the heat of a fire, which will prevent the passage of fire and smoke for up to 5 hours in both integrity and insulation. In normal use, it will also maintain the sound reduction index of a structure.

FireMastic-300’s superior acoustic properties mean it offers up to a 63dB sound reduction, making it ideal for high performance STC installation.
