AS202200 ml
High-Temperature RTV Silicone Gasket Maker, Black
The AXIOM® AS202 high-temperature one-component automotive silicone sealant with an «acetoxy» curing system is used for repairing or replacing gaskets in vehicle assemblies exposed to high temperatures, such as the gearbox housing cover, the thermostat housing, the engine sump and the water pump. It can be applied over the standard gaskets to improve their performance. It is not recommended for use on the cylinder head.
It is characterised by excellent adhesion to steel, cast iron and aluminium surfaces. Thixotropic, it does not run or sag from vertical surfaces during application. It vulcanises at room temperature (RTV) and forms a strong, flexible gasket. It does not crack or shrink.
The ergonomic design of the applicator ensures even application and accurate dosing; it prevents the contents from drying out between uses, which allows the product to be used repeatedly. Blog article →
- Work is recommended at an ambient temperature between 5°C and 40°C and a sealant temperature of 20–25°C.
- The sealant is applied to clean, dry and degreased 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”.
- Remove the tamper-evident tab and take off the protective cap. Activate the applicator by smoothly turning its head clockwise towards “MAX”; the applicator trigger will then rise into the working position.
- The bead thickness is controlled by the pressure on the trigger, the speed at which the applicator is moved and the angle between the nozzle and the application surface.
- Apply the sealant as a continuous uniform bead to one of the surfaces, first along the inner perimeter, then around the fastener holes. Join the surfaces immediately, before the silicone has set. After the sealant has vulcanised, no additional retightening of the bolts is required.
- On completion of work, to fully close the valve and prevent unwanted dispensing, turn the applicator head anticlockwise as far as it will go towards “MIN”, clean the nozzle and fit the protective cap.
- Clean surfaces contaminated with sealant using a solvent (white spirit, acetone) before the sealant cures.
- Remove excess cured sealant mechanically using A9605 “Sealant remover”.
- Skin formation time – 18-20 minutes, sealant vulcanisation rate – 2 mm per day (at a temperature of +23°C and a relative humidity of 55%).
