LOCTITE threadlockers come in four different package colours to distinguish their functions.

Henkel is the source to trust for the widest selection of LOCTITE industrial adhesives – including four types of threadlockers, distinguished by different colours. These products cater to a broad range of applications within all industries. While all the bottles are red, the colour refers to the actual substance (red, blue, green, and purple), which helps customers to tell the difference between the four types, which have varying strengths and/or uses.

A wide temperature resistance

Intended for metal-to-metal tasks, LOCTITE threadlockers blend complex chemistry and engineering into anaerobic adhesives that users apply by drops to the threads of fasteners; every one cures to a hard thermoset plastic that locks threads together. Each of these products has a wide temperature resistance from -53 to at least 148 degrees Celsius.

Red Threadlocker
The highest strength available in LOCTITE threadlockers is the Red version. Available as a liquid or semisolid anaerobic, and in a primerless-grade version, Red threadlocker cures completely in 24 hours and requires heat for disassembly.

Blue Threadlocker
LOCTITE Blue threadlocker is a medium-strength adhesive that also cures fully in 24 hours and is available in liquid or semisolid form and in a primerless-grade version. Users can disassemble Blue threadlocker with hand tools. Henkel offers LOCTITE QuickTape 249, the only threadlocker of its kind worldwide.

Green Threadlocker
LOCTITE Green threadlocker is designed for locking pre-assembled fasteners like electrical connectors and set screws and is categorized as medium-to-high-strength for wicking. This threadlocker is available solely in a liquid form; it cures in 24 hours, and users can remove it with either heat or hand tools.

Purple Threadlocker
LOCTITE Purple threadlocker is one of the most successful Henkel products. Also known as LOCTITE 222, this is a threadlocker that can be used on aluminum, brass, and other low-strength metals – which provides plenty of flexibility for the user. Like the other colours, LOCTITE 222 also cures in 24 hours.

The LOCTITE XPLORE online e-learning platform, which was launched last year, includes information on using these threadlockers – specifically, on how threaded assemblies work and how to prevent failures in them.
