Athesil is a high-performance RTV silicone (Room-Temperature-Vulcanizing) developed by Athena – a world leader in aftermarket gaskets and sealing products. It is designed to meet the high demands of professional mechanics in the automotive, marine, motorcycle, industrial, and off-road sectors.
Athesil can be used as a sealant, adhesive, or as a formed-in-place gasket (FIPG) for components made of glass, plastic, or metal – such as crankcases, pumps, and flanges.
Once cured, Athesil forms a strong, flexible, and waterproof silicone seal that resists aging, weather, and thermal cycling – while remaining permanently elastic.
Key features:
- RTV silicone – cures at room temperature without shrinking.
- Extremely versatile – seals, bonds, repairs, and fills gaps.
- Ideal for engines – used as FIPG (Formed-In-Place Gasket).
- Flexible and waterproof – remains elastic and resists aging and weather.
- Withstands temperature variations – thermally stable from -40°C up to 300°C.
- Safe for lambda sensors – suitable for use in modern engines.
- Easy to apply – smooth texture and quick handling.
- Safe for users and the environment – non-toxic and non-flammable.
Athesil is the obvious premium choice for repairs and maintenance in engine environments.
