Information

LOCTITE® SI 5940 is a black, multi-substrate, acetoxy silicone compound primarily used as a general purpose sealing and bonding agent, gap-filling rubber adhesive or FIPG (form-in-place gasket). It cures when exposed to moisture in the air to form a tough, flexible, waterproof, oil-resistant silicone rubber bond. It's solvent-free and offers excellent resistance to ageing, shrinkage, cracking and discolouring. LOCTITE SI 5940 adheres to an array of materials, including clean metal, glass, most non-oily woods, silicone resin, vulcanised silicone rubber, ceramic, natural and synthetic fibre and many painted and plastic surfaces. Though typically used in applications with an operating range of -50°C to 200°C (-58°F to 392°F), it can short-term handle temperatures up to 220°C (428°F).
