A one component, highly qualified, acrylic based firestop sealant that provides movement capability in fire rated joint applications. It will transfer into foam above 200°C and it comply with fire rating specification of EN 1366-4: 2006.The product is almost odor free and is not corrosive towards metals. After applications, the product forms a tough plastic elastic rubber by evaporation of water from the sealant.
Especially for indoor joints where high demands are to be met as a fire resistant seal:
Joints in fire retardant constructions in buildings, houses and ships.
Perimeter pointing around door and window frames, concrete and brickwork.
Joints between walls and ceilings.
Joints around pipe and cable work.
Joint dimensions do have effect on the fire retarding properties. The deeper the joints are sealed, the better the fire retarding properties.
In general, it will show good adhesion without a primer on building materials like concrete, brickworks, painted wood, anodized aluminum and uPVC.
