Loctite 262 is a high-strength, medium-viscosity, anaerobic threadlocker that has been widely used in various industries for its reliability and effectiveness in securing threaded fasteners. This threadlocker is part of the Loctite brand, which is renowned for its high-quality adhesives and sealants. The specific properties of Loctite 262 make it an ideal choice for applications where vibration and shock are significant concerns, as it provides a strong and durable bond that resists loosening over time.
The chemical composition of Loctite 262 is based on a mixture of methacrylate esters and other additives that contribute to its curing mechanism. When applied to a threaded assembly, it cures in the absence of air (anaerobically) to form a strong, cross-linked polymer that fills the microscopic gaps between the threads. This curing process is accelerated by the presence of metal ions, which are typically abundant in the materials used for fasteners. As a result, Loctite 262 provides a high level of locking torque, making it suitable for a wide range of applications, from automotive to industrial manufacturing.
