Protecta FR Acrylic Sealant
Protecta FR Acrylic is a high-performance, fire-rated mastic sealant designed to prevent the spread of fire and smoke through joints and openings in fire-rated walls and floors, including those formed around building service penetrations. Assessed to AS1530.4-2014 and AS4072.1-2005, it delivers exceptional fire resistance, acoustic insulation, and smoke-sealing capabilities. Compatible with a wide range of construction materials, the sealant cures under atmospheric conditions while maintaining long-term flexibility - accommodating joint movement up to 12.5%. Under fire exposure, it activates at approximately 180°C, expanding to form a durable intumescent char that effectively prevents the passage of fire and smoke for up to - and beyond - 4 hours. Protecta FR Acrylic ensures a reliable, long-term solution with a working life of up to 30 years.
