From Loctite: LOCTITE® SI 5015 is a blue, 1-part RTV (room temperature vulcanizing) acetoxy silicone paste, which cures at room temperature on exposure to moisture in the air to form a tough, flexible, silicone rubber gasket. This product resists aging, weathering, and thermal cycling without hardening, shrinking or cracking. Ideal for stamped parts and safe for use with automotive oxygen sensors. Typical applications include valve covers, timing gear covers, differential covers, oil pans, transmission pans, water pumps, and thermostat housings. This product is typically used in applications with an operating range of -54°C to 204°C (-65°F to 400°F).
