High-Temperature RTV Silicone Gasket Maker, Black
The AXIOM® AS182 high-temperature one-component automotive silicone sealant is used for forming or repairing gaskets in vehicle assemblies exposed to high temperatures, such as the engine sump and gearbox sump, 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 vulcanises at room temperature. It forms a strong, elastic gasket (elongation at break 500%). It has increased adhesion to steel, cast iron and aluminium surfaces. It does not cause corrosion and is resistant to automotive service fluids (lubricants, coolants, acid and alkali solutions). It fills cavities and gaps up to 7 mm. The cured sealant can be used in the temperature range from –60°C to +345°C (for short periods). Blog article →
- Vulcanises at room temperature
- Operating temperature range from –60°C to +345°C
- Fills cavities and gaps up to 7 mm
- Not degraded by automotive service fluids (oils, antifreeze, brake fluid, etc.)
- Withstands high loads and vibration
- Does not cause corrosion
For gasket replacement and sealing of:
- the engine sump
- the gearbox housing cover
- the water pump
- the inlet manifold
- the thermostat housing
- Work is recommended at an ambient temperature between +5°C and +40°C and a sealant temperature of +20–25°C.
- Before applying the sealant, clean, degrease and dry the surfaces. To remove traces of old sealant it is recommended to use A9605 “Sealant remover”. For degreasing and cleaning – A9601 “Brake and clutch parts cleaner”.
- Using the supplied nozzle, apply the sealant as a continuous uniform bead 2–3 mm thick to one of the surfaces; first along the inner perimeter, then around the fastener holes, and join the parts without waiting for polymerisation to begin.
- Skin formation time – 5 minutes; full vulcanisation time – 24 hours (at a temperature of +23°C and a relative humidity of 55%). After the sealant has vulcanised, no additional retightening of the bolts is required.
- On completion of work, clean the nozzle tip and close the tube.
- Clean surfaces contaminated with uncured sealant using a solvent (acetone, white spirit).
- Remove excess cured sealant mechanically using A9605 “Sealant remover”.
