Loctite® 582 is a blue, medium-strength, fast-curing anaerobic thread sealant designed specifically for metal threaded connections up to M56/R2”. It cures in the absence of air between close-fitting metal surfaces, forming a durable seal that prevents loosening and leakage due to shock and vibration.
Loctite® 582 is a single-component, anaerobic sealant formulated for locking and sealing metal threaded pipes and fittings. Its thixotropic nature ensures easy application without migration, making it ideal for overhead and vertical applications. The product cures at room temperature when confined in the absence of air between close-fitting metal surfaces, forming a durable, chemical-resistant seal. Loctite® 582 is particularly effective on less active substrates such as stainless steel and plated surfaces and can cure through light coatings of industrial oils and cutting fluids without the need for prior cleaning. The adhesive exhibits temperature resistance up to 150°C, ensuring long-term reliability in demanding environments.
