A one part, low modulus fire resistant silicone sealant.
A one-part, low modulus, fire resisting silicone sealant, which cures on exposure to moisture vapour to form a very elastic silicone rubber. It has good adhesion to concrete, metals, and many other common building substrates.
Recommended for perimeter sealing of fire doors and screens, high movement fire-resistant joints, and fire retardant glazing in conjunction with Arboseal Intumescent Tape. It is not recommended for trafficked floor joints, overpainting, or use against natural stone.
