This one-part, water-based intumescent sealant is used for sealing construction joints and service penetrations in both vertical and horizontal applications. It is extensively tested and suitable for a wide range of service penetrations and joint configurations, making it a universal firestop solution for most applications. The sealant offers excellent acoustic properties and is formulated to be halogen- and solvent-free. It provides primerless adhesion to a wide range of porous and non-porous substrates, is approved for infinite linear gap lengths, and features excellent slump characteristics. The high-temperature silicone sealant is suitable for sealing joints around cookers, ovens, fireplaces, boilers, industrial furnaces, and joints in heating, ventilation, and sanitary installations. It offers high temperature resistance and strong chemical resistance, allowing use in chemically exposed environments. Very good adhesion to smooth surfaces ensures complete sealing and reliable performance. The material is easy to apply and smooth out, enabling efficient, simple, and time-saving installation.
