TREMstop™ FBF is a Class III single-component polyurethane foam that will cure rapidly once applied. This gun-grade rigid foam is resistant to flame, heat, decay, water, and many chemicals. TREMstop FBF is intended to block or reduce air movement around common small interior thru-wall and fire penetrations during a fire event reducing the amount of oxygen available for flame propagation.
FEATURES & BENEFITS
TREMstop FBF is a rapid curing rigid foam that demonstrates excellent adhesion to a variety of substrates. This foam is compatible with most common construction substrates, including concrete, masonry, stone, plaster, wood, fiber cement, metal, and many plastics.
