Loctite 5940 sealant is primarily used as a general purpose sealing and bonding agent, as a space-filling rubber adhesive or formed-in-place gasket. It cures on exposure to moisture in the air to form a tough, flexible, waterproof, oil-resistant silicone rubber bond.
The sealant adheres to clean metal, glass, most types of non-oily woods, silicone resin, vulcanized silicone rubber, ceramic, natural and synthetic fibre and many painted and plastic surfaces.
Operating temperature range -50 to +200°C (Intermittently up to 220°C)
