PSC Froschmarke Boiler Putty is a high-temperature refractory sealing compound formulated with potassium water glass for demanding boiler, furnace, and stove applications. Engineered to withstand direct flame and temperatures above +1000 °C, it provides strong adhesion, does not shrink upon curing, and forms a reliable barrier against smoke and gas. Ideal for thermal insulation repair and sealing tasks, it’s trusted for sealing flue gas paths, exhaust elbows, and manhole covers in high-heat industrial environments.
