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
