Fire-Resistant Sealing
Sika Boom®-400 Fire is a single-component, self-expanding polyurethane foam developed to seal interior wall joints that must maintain fire compartmentation. Its formulation achieves a fire resistance rating of up to EI 240 in the tested configurations.
Manual or Professional Application
The container allows the product to be applied using a caulking gun or the included nozzle, making it suitable for both professional projects and localized repairs. It is suitable for joints with widths between 10 and 45 mm and depths of 100 to 200 mm, always in accordance with the design specified in the corresponding fire resistance rating.
Yield and Curing
It comes in a 750-ml aerosol can and offers an approximate yield of 33 liters when applied with a spray gun or 28 liters when applied manually. It is touch-dry in about 5–6 minutes and fully cures after approximately 12 hours. It withstands operating temperatures ranging from −40 °C to +90 °C.
