Protecta FR Acrylic is designed to prevent the spread of fire and smoke through joints and openings in fire-rated walls and floors, including openings formed around building service penetrations. Protecta FR Acrylic will also maintain acoustic design performance. When subjected to atmospheric conditions, the sealant cures; however, it will retain a degree of elasticity for joint movement.
Protecta FR Acrylic creates a robust fire seal under fire exposure by the formation of a durable intumescent char. Protecta FR Acrylic can be used with suitable filling material, i.e. stone wool or Protecta backing material, to secure the correct width to depth ratio and reduce the sealant’s shrinking during curing.
The minimum depth and maximum width of the joints are included in the installation instructions. Thermal activation takes place at approx. 180°C when the material will expand (intumesce) and prevent the passage of fire and smoke for periods up to and beyond 4 hours.
