LOCTITE 242 is a medium-strength anaerobic threadlocker engineered for the reliable locking and sealing of threaded fasteners. This industrial adhesive prevents loosening and leakage effectively. It withstands shock and vibration in demanding environments. Crucially, it permits normal disassembly using standard hand tools, simplifying maintenance. This makes it ideal for components requiring routine servicing.
General Information of LOCTITE 242
This advanced formulation is based on acrylic technology. Its chemical composition is a dimethacrylate ester. The product presents as a distinct blue liquid in its uncured state. It also exhibits positive fluorescence under UV light, aiding inspection. LOCTITE 242 is a convenient one-component system. Therefore, it requires no pre-mixing before application. The adhesive features a medium, thixotropic viscosity. This characteristic prevents liquid product migration after application to the substrate. The curing mechanism is anaerobic. It hardens when confined between close-fitting metal surfaces in the absence of air. Furthermore, a secondary cure can be initiated with an activator. This accelerates hardening on less active substrates, such as plated surfaces.
Key Features & Technical Benefits
- Medium Strength: Enables straightforward disassembly of threaded fasteners with common hand tools.
- Thixotropic Viscosity: Reduces liquid product migration, ensuring precise application and containment.
- Anaerobic Curing: Cures reliably in the absence of air between metal surfaces, forming a robust bond.
- Shock and Vibration Resistance: Effectively prevents fastener loosening and leakage under dynamic loads.
- Versatile Substrate Compatibility: Suitable for use on less active metals, expanding application flexibility.
Typical Industrial Applications
This formulation is engineered for the following applications:
- Locking and securing threaded fasteners in general industrial assemblies.
- Sealing threaded connections to prevent fluid or gas leakage.
- Securing components on plated or inactive metal surfaces requiring future serviceability.
