High-Temperature RTV Silicone Gasket Maker, Gray

The AXIOM^® ASK145 high-temperature one-component silicone sealant is used for forming or repairing gaskets in vehicle assemblies exposed to high temperatures, such as the engine and gearbox sumps, the water pump, the timing gear cover, the thermostat housing and others. It can replace gaskets and oil seals as well as paper, rubber, metal and other seals. It can be applied over the standard gaskets to improve their performance. It is not recommended for use between the cylinder head and the cylinder block!

Neutral, it contains no solvents or acids, does not cause corrosion and can be used for sealing electrical connections and sensors. It is suitable for sealing and repairing vehicle headlights. It fills cavities and gaps up to 7 mm.

It has increased adhesion to steel, cast iron and aluminium surfaces. It is resistant to automotive service fluids (lubricants, coolants, acid and alkali solutions). The room-temperature vulcanising (RTV) silicone forms a strong, elastic gasket (elongation at break 500%). The cured sealant can be used in the temperature range from –60°C to +345°C (for short periods). Blog article →
