What is a Retaining Compound and How is it Used?
Kemtite Anaerobic Retaining Compounds are formulated to deliver exceptional shear strength for non-threaded cylindrical metal assemblies. This advanced anaerobic adhesive fills gaps in close-fitting parts, curing into a durable thermoset-plastic that forms a single, solid bond. Engineered to seal joints, these compounds effectively prevent leakage, corrosion, and mechanical seizure, ensuring reliable performance. Widely trusted for press-fit and slip-fit assemblies, Kemtite products provide a standard solution for enhancing durability in industrial applications.
Retaining compounds are high-strength adhesives that fill the gaps between metal surfaces to join cylindrical components like shafts, bearings, bushings, and pulleys. It forms a strong bond that is resistant to stress, vibration, and high temperatures when it cures in the absence of air and in contact with metal.
Retaining compounds enhance load transmission, prevent fretting corrosion, and eliminate the need for press fits or mechanical fasteners. This increases assembly reliability and reduces maintenance. This is why they are often used in the manufacturing, heavy equipment, and automotive sectors.
