Where Can I Use FF197
Nullifire's FF197 is used to seal linear gaps throughout the fire rated areas of a building. This pink fire foam is easy to identify and cures to form a semi-rigid foam that can accommodate some degree of movement of the joint.
FF197 acts as an effective fire seal for up to 4 hours (BS EN 1366-4) when used with FS702 Intumescent Acrylic or FS703 Silicone Sealant
