B2 Fire Retardant Foam - Hand Held (1 Pack) - Fischer

Fischer B2 Hand Foam Fire Retardant - 750ml Fischer B2 Fire Retardant expanding foam has been formulated using polyurethane base and various fire retardant additives. Fischer B2 foam has been tested in accordance with DIN4102 B2 classification. When used in conjunction with intumescent sealant or building mastic Fischer B2 foam will create a barrier that can withstand fire for up to 2 hours. Thanks to its great fire resistance we recommend this foam for filling gaps between walls and ceilings, openings in walls and gaps around window and door frames. Cured foam can be removed fairly easy by hand. Adhesion can be improved by dampening surfaces with clean fresh water. Please remember that Fischer B2 foam should not be exposed to UV light as that can have an adverse effect on the foam.
