FS-C
FS-C gap sealing material is a single component and neutral silicone sealant, which is characterized by good flexibility and adhesive performance. When it burns, it will form a dense mesh structure and can effectively prevent flame and heat from transferring. This kind of sealant is widely used for the fireproof and sealing in large displacement of floor, wall crack , etc. And it can also be used in splicing the cracks of fireproof board.
