Rapidstick™ 8680 Retaining Compound is a fast curing, high strength, medium viscosity compound for cylindrical joints that prevents loosening and leakage due to vibration and shock. It develops high strength rapidly when confined in the absence of air between close fitting metal surfaces.
8680 is designed for filling gaps with up to 0.15mm diameter clearance. It is typically used for retaining sleeves, pulleys, gears, rotors, and fans on shafts, as well as securing bushings, bearings, and plugs in housings. It is an excellent retaining, sealing, and threadlocking compound.
