High-quality installation foam with a reusable adapter. Advantages : The resealable adapter allows you to reuse a previously opened can, improving product functionality. The ergonomic handle fits perfectly in your hand and makes the foam easy to use. Proven sound absorption of 60 dB meets the standards for modern sound insulation. fischer PU 750 mounting foam is ideal for filling, insulating, and insulating window joints and filling connecting gaps in door frames, prefabricated elements, wall joints, wall penetrations, and recesses. Ensures very high acoustic insulation of joints. PU 750 tubular foam is equipped with an adapter that enables subsequent use of open cans. The robust valve ensures the highest safety against blockages and gas loss. Applications: Insulating and filling gaps around windows, window sills, and roller shutters. Gluing and sealing manhole rings. Insulating and filling in roofing and drywall work. Insulating and filling pre-fabricated built-in elements, wall joints, wall penetrations and voids Building materials. Bonds to all standard building materials: concrete, anodized layers, plasterboard, wood, silicate bricks, plastics (not PE, PP, Teflon, silicones), masonry, metals with primer, plaster. Single-component polyurethane (PU) foam. Flammability class: B3. Color: yellow. Yield (slow foaming): approx. 40 l. Ambient/substrate temperature during installation: from +5°C to +30°C. Can temperature during installation: from +10°C to +30°C. If the can is too cold, bring it to room temperature. Moisten the surface before using the foam. Workable after approx. 45 minutes (at +20°C). Fully hardened after 24 hours. Remains resistant to temperatures from -50°C to +90°C. Layer thickness > 50 mm: apply the foam in several layers, allow each layer to dry and then moisturize. Immediately after the foam is fully cured, protect it from UV radiation using, for example, plaster, paint. Fresh traces of foam contamination can be immediately removed with fischer PU remover. Store at temperatures between +10°C and +30 °C.
