LOCTITE 566040ML Silicone Sealant
LOCTITE SI 5660 is a moisture-curing, grey, lump-free silicone gasket sealant designed for high resistance to oils and coolants. Ideal for transmission and cast metal housings, it reduces migration after application due to its thixotropic nature. Suitable for gasketing in industrial applications, it offers room temperature vulcanizing curing, excellent chemical and thermal resistance, and durable mechanical properties including a Shore hardness of 45-75 and tensile strength of 2.4 to 3.8 N/mm². It ensures strong, flexible seals in demanding environments.
