Athesil is Athena’s next-generation single-component RTV silicone sealant, designed to meet the needs of professional technicians across the automotive, motorcycle, industrial, marine, and offroad sectors. Highly versatile, Athesil is the ultimate solution for sealing, bonding, repairing, and assembling a wide range of materials and components.
Versatile and reliable for multiple applications
Athesil can be used as a FIPG (Formed-In-Place Gasket) for direct sealing of engine cases, pumps, flanges, and metal, plastic, or glass components. Once cured by ambient moisture, it forms a flexible, durable, and waterproof silicone rubber seal that retains its properties over time.
Superior chemical and thermal resistance
Athesil is resistant to fuel, oil, water, and technical fluids, and remains elastic even under extreme thermal cycles, from intense cold to high heat. It is lambda sensor-safe, non-toxic, non-flammable, and easy to apply—ideal for fast, safe, and professional use.
