FR Acrylic

iPASSIVE FR Acrylic is a fire-resistant sealant designed to prevent the spread of fire and smoke through joints and openings in fire rated walls and floors for up to 4hrs and beyond.

Product Description

iPASSIVE FR Acrylic cures to give a firm and flexible seal when subjected to atmospheric conditions. In exposure to fire, iPASSIVE FR Acrylic creates a fire seal by forming a robust intumescent char. iPASSIVE FR Acrylic will also maintain the acoustic performance in walls and floors.

iPASSIVE FR Acrylic can be used with a suitable backing material in order to ensure the correct seal depth and reduce shrinking of the sealant during curing.
