Threadlockers

Threadlockers – A threadlocker is a hard-setting sealant and adhesive compound used to lock threaded connections. Between all industries, home and DIYers, there are millions of threaded connections made each year and every one of them tends to loosen with time unless they are mechanically or chemically locked. The main causes of loosening, that is the loss of clamp force, are load, vibration and corrosion. Threadlockers are used in many cases in place of traditional mechanical washers and fasteners and often outperform the mechanical solutions.

Most threadlockers are anaerobic epoxies that create a strong bond between opposing threads and fill surface imperfections, locking the threads in place. “Anaerobic” refers to the property of an epoxy curing in the absence of oxygen which is not present in the sealed threads. There are different kinds of threadlockers ranging from general-purpose to those for use in specific applications or environments.

A good threadlocker should cover the following properties:

Vibration resistance
Anticipated load resistance
An acceptable cure time at room temperature
Chemical compatibility with acids, alkalis, water, hydrocarbons and solvents, as required
Corrosion resistance
An acceptable consistency for easy, even application

What are the common applications of a Threadlocker?
Threadlockers are used in different applications, from Residential, MRO Industrial to specific Industrial Equipment. Some of these applications include:

Horizontal Directional Drilling
Oil & Gas Drilling
Water Pipeline Assemblies
Gas Line Assemblies
Automotive Maintenance
Aerospace Assemblies
MRO Industrial
