Application of torque sealant on an aircraft

Torque sealant and its range of applications

Although torque sealants can look back on almost 60 years of existence (Lackfabrik Bäder GmbH & Co. KG has been selling torque sealants since 1962), their general function and thus their range of applications is, if at all, only very sparsely documented. There are several reasons for this.

First, the torque sealant market can be considered small in relative terms compared to other industries, which is why there is only limited public interest in it. Secondly, the term "torque sealant" can be confusing, as it describes only part of its range of applications.

Nevertheless, torque sealants are used extensively in a variety of industries. These include, among others, the automotive industry, the aviation and aerospace industry, the rail and railroad industry or, for example, manufacturers and service providers of fairground rides. The bottom line is that it is hard to find industries in the manufacturing sector that do not have some contact with torque sealants. Why? Because screws are used everywhere. And where there are screws, there is usually torque sealant.

Due to the wide range of applications of torque sealants five different main fields of application have emerged over the years.

Torque loosening indicator

Torque sealant is used as a torque loosening indicator to immediately detect loosening of safety-related fasteners.
