Loctite 135522 Yellow 641 Medium Strength Retaining Compound Liquid, 50 ml, -55 to 150 °C, Bottle

Loctite 135522 641 Medium Strength Retaining Compound is a high-quality liquid adhesive engineered specifically for use in industrial, maintenance, and repair settings. Packaged in a 50 ml bottle, this yellow, medium-strength compound is designed for bonding cylindrical fitting parts, such as bearings, bushes, and oil seals, especially where subsequent disassembly is required for service operations. The product is easy to apply, cures in the absence of air between close-fitting metal surfaces, and provides robust adhesion due to its methacrylate composition.

Its medium viscosity ensures simple application and prevents loosening and leakage caused by shock, vibration, or minor surface irregularities. With a working temperature range from -55 °C to 150 °C, this adhesive is suitable for a wide array of conditions. The cure time varies from 6 to 24 hours, offering flexibility depending on usage and environmental factors.

The 641 retaining compound is formulated to fill minor voids between mating surfaces to improve load transmission and reduce the need for close-tolerance machining. By preventing fretting and corrosion between bearing surfaces, it enhances the operational life of assemblies and ensures continued reliability under demanding conditions.

This Loctite product is ideal for both original equipment manufacturing and maintenance operations. Typical applications include the retention of slip-fitted and light press-fit parts in machinery, automotive, and equipment manufacturing, as well as maintenance, repair, and overhaul (MRO) of bearings, shafts, and cylindrical assemblies.

Designed for reliable retention of bearings, bushes, and oil seals. Cure time ranges from 6 to 24 hours for optimal performance. Functions in a wide temperature range from -55 °C to 150 °C. Prevents corrosion and leakage by filling gaps between metal surfaces.

Medium strength suitable for parts that may need subsequent dismantling. Composed of methacrylate for robust curing and adhesion. Yellow color and medium viscosity simplify application and identification. Packaged in a 50 ml convenient bottle format for industrial and maintenance use.

Industrial, maintenance, and equipment assembly users will benefit from this reliable bonding solution, ensuring secure fit and reduced maintenance needs. Explore more high-performance retaining solutions from Loctite in the adhesives and glues portfolio at EnvMart.
