    Description

    Nullifire FS703 Intusil Fire Resistant Silicone Sealant  provides a fire-stopping seal around high movement joints and is ideal for use in external aggressive environments, with high adhesion that applies to high-sheen surfaces like glass and aluminium. The mastic insulates and resists fire for up to 240 minutes with a water-resistant seal that is unaffected by moisture, offering a movement capability of up to 50%.

    Intusil cures at a rate of 1 mm per day and cannot be readily over-coated.
