Intumescent graphite sealant is an environmentally friendly single component fireproof sealing material, which can be brushed with sealing paint to quickly and effectively seal difficult to enter gaps. The construction is fast and simple, the surface is brushed, water-based, and the overflow area is easy to clean. It has strong bonding performance and is suitable for the joints between curtain walls and floor edges as well as gaps with high elongation. It does not contain halogens and asbestos, has good smoke and water tightness, excellent elastic deformation ability, and will not dry or crack during use. When a fire occurs, it expands due to heat and quickly and effectively seals the gaps left by the combustion of combustibles in the fire. The maximum fire resistance time can reach 3
hours
The combustion performance shall not be lower than B2 level specified in GB8624-2012
