Industrial Rock River 100 Percent RTV Silicone High Temp Red Sealant 300ml Sealant

Industrial Rock River 100% RTV silicone high-temperature red sealant, packaged in a 300 ml cartridge, provides a durable, heat-resistant seal for high-heat joints. This one-component RTV silicone cures at ambient conditions to form a flexible, gap-filling seal capable of withstanding temperatures up to 600°F (315°C). The red formulation helps identify heat-resistant seals in assemblies where thermal resistance and reliability are essential. Suitable for use in industrial maintenance and repair, it adheres to a range of common substrates encountered in demanding environments, including metal surfaces. Typical applications include sealing around components in exhaust systems, furnaces, ovens, boilers, and heating elements, as well as other high-temperature joints that require long-term resistance to thermal cycling and exposure to oils or solvents found in industrial settings. The 300 ml size offers sufficient material for medium-scale projects or routine maintenance tasks, enabling direct application in tight spaces where quick, one-step sealing is advantageous. For best results, ensure surfaces are clean and dry before application and allow cure to complete according to product guidance, establishing a resilient seal that maintains integrity under repeated heating and cooling cycles.
