Pereseal FR Fire-rated Intumescent Acrylic Sealant

PERESEAL FR is a fire-rated intumescent acrylic sealant for passive fire protection in fire-rated applications.It cures to form a firm yet flexible seal to join a variety of materials and applications. When exposed to heat, PERESEAL FR chars and expands, preventing the spread of heat, smoke, and fire through a joint.
