Lukitusaineen

Lukitusaineen, commonly known as threadlocker, is a liquid chemical compound used to secure threaded fasteners, such as nuts and bolts, against loosening due to vibration and shock. It works by filling the microscopic gaps between the mating threads of the fastener and the component it is being attached to. Once cured, typically through anaerobic polymerization (meaning it hardens in the absence of air), it forms a rigid or semi-rigid bond.

There are various formulations of threadlockers, categorized by their strength and viscosity. Low-strength threadlockers are designed for easy disassembly and are often used on smaller fasteners or where frequent adjustments might be needed. Medium-strength threadlockers provide a more robust hold, suitable for general-purpose applications where vibration is a concern but disassembly is still expected. High-strength threadlockers create a permanent bond, requiring heat or significant force to break the bond, and are typically used in applications where loosening would be catastrophic.

Threadlockers are available in different colors, which often indicate their strength. For example, blue is commonly associated with medium strength, red with high strength, and green with wicking or low strength. The application process involves cleaning the threads of both the fastener and the hole, applying the threadlocker to one of the components, and then assembling the parts. The curing time can vary depending on the product, temperature, and the type of metal involved. It is a widely used product in automotive, aerospace, and general industrial maintenance to enhance the reliability of mechanical assemblies.
