Bond It B1 Hand Held Fire Resistant Expanding Foam is a pink polyurethane foam for filling gaps, sealing joints and improving thermal and acoustic insulation. This 750ml version uses a straw adaptor, so no foam gun is required. It adheres to most common construction materials and meets Class B1 to DIN 4102-1. Apply between +5°C and +30°C and shield cured foam from UV light. Fire performance is limited to tested configurations. Do not use it as a fire-resistant seal around designated fire doors. Follow the technical and safety data sheets.
