Product Description
LOCTITE 638 High-Strength Retaining Adhesive for Cylindrical Metal Components
LOCTITE 638 is a one-component, high-viscosity, anaerobic acrylic adhesive designed for robust bonding of cylindrical fittings. It cures in the absence of air between metal surfaces and offers high strength, oil tolerance, and compatibility with both active and passive substrates.
Product Overview
LOCTITE 638 is engineered for applications where bond gaps can reach up to 0.25 mm and maximum room-temperature strength is required. It prevents loosening and leakage under shock and vibration, making it ideal for demanding industrial environments.
